How can I learn inorganic and analytical chemistry well and bring up my interest in it

Romantic, affectionate love is largely based on external attraction, typified by love at first sight;

Think about what you will do in the future, and if it is related to the subject and you need it, then you will study hard.

When doing calculations, inferences, etc., I think of them as a mind game, and I have always thought that inference problems are fun, starting from nothing, and not very successfulAnd when you do the math, try to imagine the process in your head. It will help you understand the gist of the problem.

Or, if your future job is related to chemistry, then it is easier to learn better if you have a goal!

The first few chapters of Wuji and analytical chemistry are a bit like high school physics, and it is difficult to learn at the beginning, but the focus is still on memorizing formulas, and then orbital hybridization is a difficult point, and if you want to learn hybridization well, you must first master the covalent bond theory. After acid-base titration, redox, etc., in fact, there is a certain foundation in middle school, on these basis, and then understand, I think the focus is still on, remember the formula such as the end error and the like.

1. Preview before class, take time to consciously preview the content to be taught the next day, develop a good learning method of previewing in advance and then listening to the class, preview can strengthen the pertinence of the lecture, help to find problems, grasp the key points and difficulties, and improve the efficiency of listening;

2. Listen to each class, listening to the class is the core link of the learning process, is the main way to learn and master knowledge, whether you can master the knowledge learned in the classroom is the key to determining the learning effect, the power is in the classroom, the benefit is after class, if you can basically master the basic knowledge and skills learned in the classroom, there will be no difficulty in reviewing and doing homework after class;

3. Learn to take notes, to learn chemistry well, note-taking is also an important part, in addition to concentrating one's attention and improving the efficiency of listening to lectures in the hall, it is also very helpful for after-class review, to learn to take notes, develop a good habit of note-taking;

4. Review in time after class, review can deepen understanding, consolidate the problems that you don't understand in the knowledge review, do not leave obstacles in learning, and lay a good foundation for smooth learning in the future.

You have to keep in mind the types of organic chemical reactions.

1. Substitution reaction.

Refers to the reaction in which some atoms or clusters of atoms in an organic molecule are replaced by other atoms or clusters.

Common substitution reactions:

halogenation of hydrocarbons (mainly alkanes and aromatic hydrocarbons);

nitrification of aromatic hydrocarbons;

the reaction of alcohol with hydrohalic acid, the reaction of the hydroxyl hydrogen atom of alcohol being replaced;

hydrolysis of esters (including oils and fats);

Hydrolysis of anhydrides, sugars, proteins. 2、

Addition reaction. It refers to the reaction in which a reagent combines with an unsaturated compound molecule to reduce the degree of unsaturation of the unsaturated compound or to generate a saturated compound.

Common addition reactions:

Olefins, alkynes, aromatic compounds, aldehydes, ketones and other substances can undergo addition reactions with hydrogen (also called hydrogenation reaction, hydrogenation or reduction reaction); addition reactions of olefins, alkynes, aromatic compounds and halogens; Alkene.

Addition reaction of alkynes with water, hydrogen halides, etc. 3、

Polymerization reactions. It refers to the reaction of small molecules with small relative molecular mass combined with each other to form a polymer with large relative molecular weight. The small molecules that participate in the polymerization reaction are called monomers, and the large molecules formed after polymerization are called polymers.

Common polymerization reactions:

Polyaddition. It refers to the reaction of small molecules with small unsaturated molecular mass combined into polymers with large relative molecular weight.

Here are some ideas for you on how to review:

1. Chapter review, no matter which discipline is divided into large chapters and small class hours, generally when all the lessons of a chapter are finished, the whole chapter will be strung together in the system to talk about it again, as a review, we can also do this, because since it is a chapter of knowledge, all the class hours must be related before, so we can find out what they have in common, and use the associative memory method to string these fragmented knowledge through the line, which is more convenient for us to remember.

2. Error correction and sorting: It is inevitable to make mistakes in the process of doing questions, whether you are careless or not, you must habitually collect these wrong questions, and each subject has a set of mistakes, when we review before the exam, they are the key review objects, so since you missed once, you may not be wrong the second time, only in this way you will not lose points again on the same problem.

3. Mind map review: Mind map is a great invention, which can systematize and visualize the information in your brain in memory, and can also help you analyze problems and plan as a whole. Drawing knowledge with a mind map to organize and memorize it can quickly analyze the context and focus of knowledge, and remember it firmly.

Be sure to take notes during class, and you can't even preview inorganic things, but you must review. Just memorize all the formulas and conditions.

Master equations, especially ionic equations

Organic Chemistry:

To read the book well, not to read more than four times is not good, the key to see is to understand, organic chemistry content is very fragmented, but very systematic, first the main prophilic mechanism, nucleophilic mechanism and free radical mechanism comparative learning, and then you will find that in fact, most of the reaction mechanism can be explained by the "electron cloud flow", including "space effect", "induction effect" and "conjugation effect", these effects must be understood.

Analytical chemistry: Analytical chemistry includes instrumental analysis and inorganic analysis, instrumental analysis needs to be learned by practice, inorganic analysis needs to be read several times first, take a good look, what is a shortcut also need to memorize some basic things.

Find a teacher by yourself, and in addition to the course experiments, follow up with some teachers' experiments.

It is best to go to the laboratory and get in touch with more experiments on organic synthesis, and the actual operation will be better remembered.

Well, this is easy to say, I can do it, it will.
