Some important reaction equations, the phenomenon of chemical reaction and how this phenomenon occurs, the chemical and physical properties of matter, the structure of organic matter, and their properties, etc., in fact, read more books, do more questions must be, the content of the exam is ever-changing, I remember that my textbooks in my first year of high school were rotten, and my chemistry grade ranked particularly high that year. But then I couldn't hold on anymore, and now I regret it a little when I think about it. Study hard!
Giving is a must;
The harvest is inevitable!

I'm a high school teacher, and I'm ashamed to say that many of my students don't like to study no matter how much they try to persuade me.
But most of them still love to learn, because we are a provincial key school, and the students are better.
In the past few years, I think organic chemistry is actually the best to learn, because its regularity is very strong, but it will be difficult at the beginning, because many things are new, and it is even more difficult when it is just synthesized, so when you need to make the knowledge points in front of you very clear, you will learn more and more smoothly.
There are a lot of things to be remembered and can be applied flexibly.
For example, we should first grasp the structure of organic matter, and then classify and study their properties, from alkanes, olefins, alkynes, benzene and benzene homologues, halogenated hydrocarbons, alcohols, phenols, aldehydes, carboxylic acids, esters.
It's almost mastered.,It's fast to synthesize.,All you have to do is remember.,This place will not be difficult if you are smart enough to use it.,If it's generally smart, remember a lot of rules.,Forcibly remember.,Slowly you'll find that when you're using.,You understand.,It's naturally getting better and better.。
Hope it helps you and good luck.

Answer: Students can deepen and broaden their comprehensive understanding of chemistry by mastering the basic knowledge of organic chemistry in a concise and systematic manner. Learning organic chemistry knowledge can be strengthened from the following aspects.
1. Classification and inductive derivation of the general formula and general properties of substances (to deepen understanding through experiments).
There are many kinds of organic matter, and in the process of learning, according to the structure, nature and relationship between structure and properties of each type of organic matter, the general formula and general properties of each type of organic matter are classified and summarized. For example, in the chapter "Derivatives of Hydrocarbons", the knowledge is based on functional groups, so when learning derivatives, we should first grasp the structural characteristics of functional groups to infer the characteristics of derivatives, and then further verify their structures by the properties, and fully understand the dialectical relationship between structure and properties. Secondly, the understanding of the properties of this type of organic matter is deepened through experiments.
2. Use molecular structure models to improve spatial imagination.
In order to understand more vividly the arrangement of atoms in the space of organic molecules. Use the second class time to go to the laboratory to combine molecular models such as CH4, CH2=CH2, CH3CH=CH2, CH3CH2OH and so on, so as to improve your spatial imagination ability, hands-on operation ability, and creative ability.
3. Master the nature and pay attention to application.
1. Contact structure and remember the nature.
2. Compare types and remember the nature.
3. Draw inferences from one case and use the nature of life.
Fourth, the foundation, good association, dare to innovate.
In recent years, in order to highlight the examination of students' ability, information giving questions often appear in the college entrance examination, which has also become one of the important reasons for the opening of candidates' scores.

Learn BAI
In organic chemistry, I especially understand the ideas and methods of organic chemistry
Grasp the learning of structural DAO. It is particularly important to understand the relationship between structure and chemical properties. The structure determines the chemical properties, and what kind of structure there is has some similar chemical properties, especially multifunctional groups, and the chemical properties are multiple.
Do a good job in the study of representative objects. It is like the learning of some similarities in the system and the particularity of a certain substance.
Organic learning, beginners usually find it difficult to get started, which is normal, as long as you get started, it is a big score. It is necessary to consider more spatial configuration and master the writing of isomers, which is the basic skill of organic learning.
In addition, the organic reaction conditions are very important, the same reactants, different conditions will be different products; Summarize more, connect before and after, and form a system.
On the whole, organic is not the difficulty.

Mechanization is mainly based on the structure of the mechanization.
1. I think it is important to say that the properties of each organism are more important than the methanation properties of the physical properties of the physical properties before making multiple-choice questions.
2. The program is wild and the funny machine program I think that it is necessary to figure out the principle and mechanism of the program and the mechanism of the program than plus: the saturated key becomes the saturated key and the key is broken.
3. In science, you must do the problems and the types of questions are different, and the accumulated experience is ruined, and in addition to the school textbook, you must buy another practice textbook.
4. I almost forgot to ask seriously, and I want to ask the teacher.
I hope that I can break through the difficulties as soon as possible!
It doesn't make sense to ask such questions.
It is advisable to go down and check the information yourself.

I did this when I was in high school and it worked really well! I believe you can succeed! There are many things that organic chemistry memorizes, and they need to be memorized! Learning is no skill, a solid foundation, in order to carry high-rise buildings, do more.
-
Be familiar with the names of functional groups and their properties, memorize the chemical formulas of important organic substances, write their reaction equations and find out where they break their bonds, and memorize several important experiments....

If you don't have skills, take every question seriously and understand the knowledge points.
If you don't know anything about the question, turn the book immediately.
Slowly, you will become familiar with the textbook.
-
Preview the basics.
Identify concepts. Review the questions carefully.
Answer the questions carefully. Summarize in a timely manner.
Look for the cause of the error.

I am a senior in high school, organic chemistry, and I personally think that anything should have a certain interest in the student number. Secondly, organic chemistry is not rote memorization, and understanding is more important. There are also things that must be remembered, such as some commonly used functional groups, commonly used reagent names and their functions, common reactions, such as substitution, addition, hydrolysis, elimination, and the law of chemical bond breaking or bond formation.
You can start with the basics, gradually understand, and you can buy some teaching aids for reference. I wish you a speedy mastery of organic chemistry. Pure hand to adopt.
-
Start by remembering typical substances such as methane, ethylene, acetylene, benzene; Halogenated hydrocarbons, alcohols, ethers, phenols, aldehydes, ketones, carboxylic acids, esters, sugars, proteins, polymers, etc.
Secondly, to keep in mind the typical chemical principle, the synthesis method is important.
Third, memorize typical chemistry experiments from textbooks.
-
There are many homologues of organic matter, remember the law.
Most of the reactions of organic matter are the reactions of functional groups, and it is almost enough to remember that the reactions between those functional groups are basically sufficient.

1.To learn inorganic, we should start from the atomic structure of elements, while to learn organic, we must start from the molecular structure, and it is very important to grasp the functional groups;
2.To learn organic, we must learn to draw analogies, substances with the same functional groups can often have the same or similar reactions, and the essence of substitution, addition, condensation, and polymerization must be thoroughly understood! Learn to write analogies about chemical reactions;
3.I have just finished learning, I use the "Efficient Learning Method", which is quite good, I should pay more attention to accumulation and practice, and learn to connect with old knowledge when encountering new things, pushing and guessing is also a way to ability and consolidate knowledge.
Hope it helps!

Learn organic pay attention to grasp the clues that structure determines properties, every time you learn a substance, you must first remember the structure of this substance and its functional group, grasp the properties of this substance, and then deduce that the substance with the same functional group also has similar properties, with such an idea, no matter how many organic matter, their properties can also be familiar with the mind, master the properties, you can apply it to do problems, most of the organic are inference problems.
It is recommended that you have a high-quality teaching aid on hand.
Hope it helps.
Integrate and systematically learn the knowledge of organic chemistry, find out the properties of substances and the similarities and differences between them, write them down in a notebook, and look at them often. >>>More
Organic chemistry is a science that studies the composition and composition, synthesis and characterization, structure and properties, reaction and transformation, as well as function and mechanism of organic substances, and is one of the important disciplines for creating new substances. The new theories, new reactions and new methods of organic chemistry not only promote the development of chemistry, but also promote the intersection and penetration of this discipline with life, materials, energy, information, agriculture and environment and other related fields, and further expand the research field of organic chemistry. >>>More
Methane and methanol have in common in their molecular composition (both have one carbon atom), and ethanol and acetic acid have in common in their molecular composition (they have two carbon atoms).Similarly, from the above analysis, it can be seen that A and B in the names of such substances are the number of carbon atoms in the molecule of the substance >>>More
At that time, it was very difficult to solve the problem of how the atoms in the molecule of organic compounds were arranged and combined. Originally, organic chemistry used binary theory to solve the structural problem of organic compounds. The dualistic theory holds that the molecules of a compound can be divided into positively charged and negatively charged, and the two are held together by electrostatic force. >>>More
Of course, there is hope, inorganic chemistry and organic chemistry are two branches of chemistry, inorganic talks about some basic and elemental knowledge, organic talks about the properties and reflection mechanism of organic compounds, etc., you can learn well, I hope you inorganic will also keep up.
