Q:Does Organic Chemistry Study the Performance of Hydrocarbons and Their Derivatives?
Also study the structure and transformation
Q:Hazardous Chemicals Inorganic Classes, Organic Classes What does it mean?
Hazardous chemicals refer to highly toxic chemicals and other chemicals that are harmful to humans, facilities and the environment, which are toxic, corrosive, explosive, burning and burning. Including explosives, compressed and liquefied gases, flammable liquids, flammable solids, spontaneous combustion and wet flammable materials, oxidants and organic peroxides, toxic and corrosive substances, etc.
Q:What is organic matter?
Organic compounds (organic compounds) mainly by the oxygen elements, hydrogen, carbon elements. Organic matter is the material basis for life. Fat, amino acids, protein, sugar, heme, chlorophyll, enzymes, hormones and so on. Biological metabolism and biological genetic phenomena, are related to the transformation of organic compounds. In addition, many substances closely related to human life, such as oil, natural gas, cotton, dyes, chemical fiber, natural and synthetic drugs, are organic compounds.
Q:Carboxylic acid and ester can form isomers. What are the conditions?
The general formula for the carboxylic acid is RCOOH, and the general formula for the carboxylic acid ester is R? COOR? (R? May be a hydrogen atom). If the total number of carbon atoms in the R group in the carboxylic acid is the same as the total number of carbon atoms of the two R groups (R + R₂) in the carboxylic acid ester and the total number of R atoms in the carboxylic acid is higher than that of the carboxyl groups R & lt; 1 & gt; R & lt; 2 & gt;), both of which constitute isomers, such as acetic acid and methyl formate, butyric acid and ethyl acetate, phenylacetic acid and methyl benzoate are all isomers.
Q:Does the carboxylic acid react with the Grignard reagent?
Reaction. Grignard reagent is an organic strong base, first and the acid reaction of carboxylic acid to produce magnesium salt, and sometimes further nucleophilic attack, control conditions will get different products, but the first acid-base reaction is unavoidable.
Q:Organic intermediates in the synthesis, what is the chemical choice
Choose the first reaction that is easy to react quickly
Q:High school chemistry: Is the esterification reaction of carboxylic acid and alcohol a polymerization reaction?
No, the polymerization reaction is the reaction of the polymer, the esterification reaction is the reaction of the formation of small molecules
Q:What are the characteristics of organic compounds?
Organic compounds are usually referred to as carbon-containing compounds, or hydrocarbon-containing compounds and their derivatives are collectively referred to as organic matter. Organic compounds are generally insoluble in water and soluble in organic solvents with lower melting points. The vast majority of organic matter heat easily decomposed, easy to burn. The reaction of organic matter is generally slow and often accompanied by side effects, and there are many kinds of organic compounds, which can be divided into two major categories of hydrocarbon and hydrocarbon derivatives. According to the organic groups contained in the functional groups, divided into alkanes, alkenes, alkynes, aromatic hydrocarbons and alcohols, aldehydes, carboxylic acids, esters and so on. According to the organic carbon molecular structure, can also be divided into open chain compounds, carbocyclic compounds and heterocyclic compounds three categories.
Q:Is the plexiglass intermediate?
Acrylic acid and its ester polymerization of the polymer obtained collectively referred to as acrylic resin, the corresponding plastic collectively referred to as polyacrylic plastic, in which the most widely used polymethyl methacrylate. Poly methyl methacrylate abbreviation for the PMMA , Commonly known as plexiglass, is so far the most transparent synthetic material quality.
Q:Is the oxygen derivative of the hydrocarbon a non-methane total hydrocarbon?
What is the total hydrocarbon for non-methane? Non-methane total hydrocarbons generally refer to all volatile hydrocarbons other than methane (which are predominantly C2 to C8), abbreviated NMHC
