Our human beings' clothing, food, shelter and transportation are inseparable from organic matter.

Organic Chemistry. The uses of learning in life are very wide, and I can't list them all, so let's just say a small part:
1. Human clothing, food, housing and transportation are inseparable from organic matter
Natural organic substances: such as sugars, oils, proteins, oils, natural gas, natural rubber.
Wait. Synthetic organic compounds: plastics, synthetic fibers, synthetic rubber, synthetic drugs, etc.
2. The synthesis and use of organic compounds with special functions have changed people's living habits and improved the quality of human life.
3. Organic matter plays an important role in the process of maintaining life activities.
Many substances in living organisms are organic matter, such as sugars, fats, and amino acids present in cells.
Proteins and nucleic acids, for example, are organic substances.
4. Most of the drugs are organic compounds, which play an important role in helping people overcome diseases and prolong their lives.

1. To ensure the survival of mankind and continuously improve the quality of human life.
1) the use of chemicals to produce fertilizers and pesticides to increase food production;
2) the use of chemical synthesis drugs to inhibit bacteria and viruses and protect human health;
3) the use of chemistry to develop new energy and new materials to improve the living conditions of human beings;
4) The use of chemistry to comprehensively apply natural resources and protect the environment to make human life better.
2. The core knowledge of chemistry has been applied to all areas of the natural sciences, and chemistry is an important pillar of the powerful force that transforms nature.
Third, the intersection and penetration of chemistry and other disciplines have given rise to many marginal disciplines, such as biochemistry, geochemistry, cosmochemistry, ocean chemistry, atmospheric chemistry, etc., which have led to the rapid development of science and technology such as biology, electronics, aerospace, laser, geology, and oceanography.

The first thing that stands out is the problem of environmental pollution. With the development of industrial society, more and more economic growth depends on the support of the chemical industry, which is bound to further cause industrial energy shortage, environmental pollution and ecological damage.
In the process of production, processing, storage, circulation and consumption of food, it will be polluted by toxic and harmful chemicals, which will cause food safety problems.
Food contamination refers to the non-production of food during production (including crop cultivation and animal husbandry, veterinary**), processing, packaging, storage and transportation.
Substances intentionally added to food, including environmental contamination and production processes (e.g. mycotoxins).
Among them, the potential foodborne hazards caused by chronic long-term ingestion of chemical organic pollutants have become the focus of attention, including pesticide residues, veterinary drug residues, mycotoxins, and certain carcinogenic and mutagenic substances formed during food processing (such as nitrosamines).
etc.), as well as industrial pollutants such as dioxins, which are well known.

What are the benefits of chemistry for the survival and development of human beings Chemistry is closely related to human social life, chemistry and the environment, chemistry and energy, chemistry and materials, chemistry and life, chemistry and medicine and nutrition, chemistry and life, chemistry and law, chemistry and philosophy, chemistry and information The value of chemistry in production and life Chemistry is a science with great practical value. By studying chemistry, we will be able to better understand and explain the chemical changes and phenomena in life and production, control these changes, eliminate or reduce the harmful aspects of these changes, and make the changes fully develop in favorable aspects. For example, by mastering the chemistry of combustion, it is possible to use fuels wisely, prevent fires, and develop new fuels**.
Using the principles of chemistry, it is possible to extract or use natural substances from nature to make various substances that do not exist in nature and are needed by human beings. For example, the extraction of salts and other useful substances from seawater; smelting a variety of metals from ores; Using air, water, oil, coal and other raw materials to manufacture plastics, synthetic fibers, synthetic rubber, fertilizers, pesticides, dyes, detergents, medical drugs and so on. The results of applied chemical research can also explore the mysteries of life phenomena, study new production processes, develop new materials, develop new energy sources, protect and improve the environment in which human beings live, promote agricultural development, increase food and nutrients, and further develop natural sciences such as physics, biology, geology, and astronomy.
In short, chemistry has an extremely extensive relationship with social life and production, and plays an important role in China's modernization of industry, agriculture, science and technology. The Value of Chemistry in Improving Human Quality As a basic natural science, chemistry plays an important role in improving human quality.

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.
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
Summary. No, the temperature of the synthesis reaction of organic matter is generally not too high, and too high a temperature may lead to the instability of the reaction products and the slowing down of the reaction rate. >>>More
and the doctrine of restitution (the doctrine of restitution of nutrients). >>>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.
