Identification of Derivatives of Chemical Hydrocarbons in High School

Answer:

Derivatives have gone, and give a specific range Well
Phenol and ferric chloride reaction, aldehyde and copper hydroxide will produce brick red precipitation, and the formation of silver diamine hydroxide silver phase precipitation, and there are aldehydes in formic acid, an aldehyde corresponding to two silver Generation, and formaldehyde can be seen as there are two aldehyde groups, can be generated corresponding to the four silver quality.
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.
Give you a formula: halogen water consumption, alcohol sodium oxygen consumption, phenolic acid picking, aldehyde plus oxidation.
