Physical chemistry is partial to theory and does not specifically address any chemical reaction.
It is relatively difficult to understand. Organic applications are relatively wide, including materials, biology, etc., and there is now a specialty called organometallic chemistry in organic, which is widely used in materials and biology. In other words, there is more organic demand.
Inorganic is currently mainly used in materials. Compared with the four disciplines, the analysis is relatively easy, and there are many instruments at present, which are relatively convenient. To sum up, it is not difficult to understand that there are many people who learn organic and analytical.
Inorganic seems to be the basis of the four major chemistry, and scientific research employment is not very clear; Organic, I am an organic major, I feel a sense of accomplishment when I do experiments as an undergraduate, but many people say that organic is difficult and difficult, but I think organic is more systematic, as long as you master it, it is basically any question type, and organic in scientific research is also very good to publish articles, like my roommate and his brother synthesized 24 kinds of single crystals when he did experiments, you must know that as long as they synthesize a single crystal in that direction, they can issue patents. <>

If you study chemistry, you will have to learn all four courses. (At least that's the case in our school...)Not chemistry majors have to learn these four subjects) From the point of view of difficulty: inorganic is relatively basic, if high school mathematics is good, inorganic is relatively simple.
At that time, there were only 2 people in our class who failed the midterm exam. But if you are an inorganic major, it is also more difficult. However, the overall inorganic is still a simpler part of chemistry.
Organic is very difficult, and if you don't have a chemical foundation, you can't understand organic at all. But if you have a chemical foundation, you may not understand it. 30% of those who take the exam will fail the mid-term examination.
Analytical chemistry, for the most part, is very simple, and the experiments are simple, except for the analysis of the structure according to chromatography. But it's generally simple, similar to high school chemistry, and no one fails the course. Reification.
This has nothing to do with chemistry, but although it is called physical chemistry, I personally think it seems to be physics....If you're not good at physics, don't study this. If you are not good at chemistry and physics, you can learn this. The personization of those who understand can be 90+, and those who don't understand will fail.
The above does not include professional courses such as advanced organic courses. Anyway, I can't understand organic from the point of view: organic is undoubtedly the best employment.
From the upstream of Sinopec to BASF Bayer Henkel, all the companies around you that produce washing, skin care, sponges, foams, etc., are in constant need of organic expertise, which can do production, R&D, sales, and procurement. Organic PhD students (with good supervisors) can earn 3k per month. Analytical chemistry.
A must-have for QC departments. Chemical companies can't live without QC, and a good quality inspection department often has a few very powerful analysts. In some fields, it is possible to infer the production process or even the process by simply analyzing the composition of the product.
At this time, if QC can measure the ingredients, it is simply an order in hand. Inorganic and materialized employment is not well understood. (According to the feedback in the comment area) there are more physical and chemical batteries, and inorganic seems to be able to engage in cement.
It should be better to meet a graduate school and give an offer. <>

In the future, I always wanted to go to the Institute of Organic Studies of the Chinese Academy of Sciences in Shanghai when I was a junior year, and then I went abroad for a public exchange by chance. Later, PostGraduate also chose the organic direction. One is that there are too many toxic and harmful substances, such as the various solvents for washing bottles, and the smell of ether acetone is very intoxicating.
The working hours at two o'clock are too long, I am a study dog, a senior postgraduate in a university in the country of rotten countries, eight in the morning and six in the evening, every day all kinds of reactions, point boards, running boards, over the column to do MRI for characterization. I'm tired day by day. It's good for girls to learn a little bit of inorganic analysis and materialization, and don't engage in organic.
There are employment prospects for organic and analytical, less for inorganic and physicochemical. Whether it is pharmaceutical, regulatory authorities, geology, water quality, food additives research and development, etc., it is related to analysis and organic. <>

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.

There are 3 differences between inorganic chemistry and analytical chemistryThe details are as follows:
1. The research content of the two is different:
1. The research content of inorganic chemistry of Qin Daji: the research of inorganic chemistry is from macro to micro, so as to link the properties and reactions of elements and their compounds with their structure; Apply modern physics and technology and the microstructure of matter to study and elucidate the composition, properties, structure and reactions of chemical elements and all their inorganic compounds.
2. Research content of analytical chemistry: analytical chemistry from elemental to complex mixtures and macromolecular compounds, from inorganic to organic, from low molecular weight to high molecular weight (imitation excitation such as 10 atomic mass units). Samples can be gaseous, liquid, and solid.
The weighing weight can range from more than 100 grams to less than milligrams.
2. The essence of the two is different:
1. The essence of inorganic chemistry: Except for hydrocarbons and their derivatives, the science of experimental research and theoretical explanation of the properties of all elements and their compounds and their reactions is one of the earliest sub-disciplines in chemistry.
2. The essence of analytical chemistry: It is an important branch of chemistry to study the analytical methods and theories of chemical information such as the composition, content, structure and morphology of substances.
Third, the main tasks of the two are different:
1. The main task of inorganic chemistry is to investigate: inorganic chemistry mainly conducts the study of inorganic compounds.
2. The main task of analytical chemistry: to identify the chemical composition of substances.

The most significant difference is organic.
The study is a macromolecular compound DAO with carbon du as the main element
Inorganic chemistry is the study of the chemistry of non-carbon substances within small molecules, with the exception of individuals. Most of the organic substances studied by organic chemistry are flammable, have no exact melting point, and have a relatively low ignition point, while the inorganic substances studied by inorganic chemistry generally have significant melting points and are relatively high, and cannot be burned.

Organic chemistry is human.
Organic chemistry, also known as the chemistry of carbon compounds, is a science that studies the composition, structure, properties, preparation methods and applications of organic compounds, and is an extremely important branch of chemistry. Carbonaceous compounds are called organic compounds because chemists in the past believed that such substances must be made by living organisms (organisms);
However, in 1828, the German chemist Friedrich Wühler succeeded in synthesizing urea (a biomolecule) for the first time in the laboratory, and since then organic chemistry has expanded beyond the traditional definition to the chemistry of hydrocarbons and their derivatives.
The term "organic chemistry" was first coined in 1806 by Betzerius ("the father of organic chemistry"). At that time, it was named as the antithesis of the "inorganic chemistry". Due to the limitations of scientific conditions, the object of organic chemistry research can only be organic matter extracted from natural animal and plant organisms.
Therefore, many chemists believe that organic chain retardation compounds can only be produced due to the existence of so-called "vitality" in living organisms, and cannot be synthesized from inorganic compounds in the laboratory. Take the pants.
In 1824, the German chemist Wühler hydrolyzed cyanine to produce oxalic acid; In 1828, he inadvertently converted ammonium cyanate into urea by heating. Both cyanide and ammonium cyanate are inorganic compounds, while oxalic acid and urea are both organic compounds. The results of Wüller's experiments gave the doctrine of "life force" its first impact.
Since then, organic compounds such as acetic acid have been synthesized from carbon, hydrogen and other elements, and the theory of vitality has gradually been abandoned.
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
