Q:What are the derivatives of hydrocarbons?
Halogenated hydrocarbons, alcohols
Q:Is acrylamide an oxygen-containing derivative of hydrocarbons?
From the structural point of view, alcohol, vinegar, malic acid, citric acid and other organic matter, can be seen as hydrocarbon molecules in the hydrogen atoms are replaced by oxygen atoms and atomic groups, they are known as hydrocarbon oxygen derivatives.
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:What is the difference between hot and cold asphalt?
I only heard the warm mix of asphalt. The How is cold asphalt defined? How much is it cool?
Q:Organic chemistry, carboxylic acid derivatives are not acid?
Your premise is in organic chemistry, the corresponding is the organic carboxylic acid. The most common derivatives of organic carboxylic acids are esters, acid chlorides, amides, and carboxylates. They are no longer part of the carboxylic acid because the dissociable protons that characterize the glycolic acid have been replaced by other groups and no longer have acid properties.
Q:What is a derivative of a hydrocarbon? What is an aromatic hydrocarbon derivative?
Hydrocarbon derivatives include derivatives of linear and aromatic hydrocarbons such as chloroethane bromopropane bromobenzene
Q:Simply talk about hydrocarbons
Hydrocarbon oil is a substitute for petrochemical diesel bio-liquid fuel, is a substitute for oil energy. It is a kind of liquid fuel produced by the lipid exchange reaction under the action of the catalyst, which is made of various kinds of lipid compounds (rapeseed oil, cottonseed oil and various vegetable oil waste) and methanol as raw materials. Burning, no black smoke, no smell, no harmful gas discharge. After testing the physical and chemical indicators have reached the national standard. Is a renewable energy source of biomass, the required wide range of raw materials, cheap.
Q:What is the most primitive person on earth?
The process of organic life is roughly divided into three steps: first the original earth simple inorganic compounds to form the original organic matter (hydrocarbons and its simplest derivatives), the second is based on the first step, gradually developed into a complex Organic compounds (sugars, nucleotides, amino acids) and their polymer polysaccharides, nucleic acids and proteins, as well as other organic substances, and the third is that with the evolution of natural conditions on Earth, the above substances are complex interactions, resulting in a metabolic Characteristics, can grow, reproduce, inheritance, variation of the original organic organisms.
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:What is the aromatic hydrocarbon
Aromatic hydrocarbons referred to as "aromatic hydrocarbons", refers to the molecule containing benzene ring structure of the hydrocarbons. Is a closed chain.
