Q:What happens to the neutralization reaction?
The neutralization reaction takes place with the hydrogen and hydroxide groups of the acid and base. The carboxylic acid group contains hydrogen ions to react with the hydroxide.
Q:Identification of Derivatives of Chemical Hydrocarbons in High School
Meaning that the halogenated hydrocarbon can be hydrolyzed and eliminated; the alcohol reacts with sodium to produce oxidation and eliminate the reaction; the phenol has acidity, can replace the reaction and color reaction; aldehyde can be added reaction and oxidation reaction. Finally remember the acid and acid, and alcohol esterification reaction.
Q:What is carbohydrate? What is organic? What is it?
Organic matter and inorganic matter is to see if there is no carbon C
Q:The nature and use of cellulose derivatives
The basic rules of esterification and etherification of cellulose In the cellulose molecule, the position of the three hydroxyl groups in the glucose group is different, and the influence of the adjacent substituents and the spatial blocking effect are different. The relative acidity and dissociation of the three hydroxyl groups are: C> C> C When the etherification reaction is carried out in the alkaline medium, the C hydroxyl group first reacts, then the C hydroxyl group, and finally the C primary hydroxyl group. In the acidic medium for esterification reaction, the reaction of the hydroxyl reaction is difficult and etherification reaction in the opposite order. When reacted with a larger amount of substituted reagents, the spatial hindrance has an important effect, and the space hindering the smaller C hydroxyl groups is easier to react than C and C hydroxyl groups.
Q:What is the definition of organic matter
Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.
Q:What is cigarization?
The so-called eggplant, cigar egg alcohol cycle strict sense of each different cigars will have a slight difference, but generally still follow a certain law. There is an economic cycle concept in economics that can be applied to the alcoholic mature cycle of cigar applications. Each cigar has a certain maturity cycle, after the peak after the quality will decline with the taste and decline. The more cigars are, the greater the impact of alcoholic time on them. For example, for three months, the impact on fresh cigars can be huge, but for five years or more the impact of cigarettes is minimal.
Q:The difference between carboxylic acid and ester
Carboxylic acid molecules must contain carboxyl R-COOH. Can react with the base, with the alcohol esterification reaction,
Q:What are the indicators of alcohol alcohol?
Just brewed liquor for some time, so that miscellaneous taste volatile, drinks inside the alcohol molecules and water molecules together, the wine will become soft.
Q:Chemical life network: chemical (inorganic reaction, organic reaction) is equal to the life of life reaction?
Inorganic chemistry is a science that studies experimental and theoretical explanations of the properties and reactions of all the elements and their compounds, in addition to hydrocarbons and their derivatives, and is one of the earliest disciplines in the development of chemistry.
Q:What is the difference between an aromatic compound and a hydrocarbon derivative?
The aromatic compound is a benzene ring containing compound, which may be a hydrocarbon or a hydrocarbon derivative. Hydrocarbons are hydrocarbon-containing compounds, and hydrocarbons containing hydrocarbons other than hydrocarbons are derivatives of hydrocarbons. The two concepts have crossed.
