STANDARD Chemistry Reactions of Amines Assertion Reason Question
Given below are two statements: Statement-I : Primary aliphatic amines react with HNO₂ to give unstable diazonium salts. Statement-II : Primary aromatic amines react with HNO₂ to form diazonium salts which are stable even above 300 K. In the light of the above statements, choose the most appropriate answer from the options given below:
Both statement-I and statement-II are correct.
Both statement-I and statement-II are incorrect.
Statement-I is correct but statement-II is incorrect.
Statement-I is incorrect but statement-II is correct.
Correct Answer
Detailed Explanation
Primary aliphatic amines react with nitrous acid to form aliphatic diazonium salts which are unstable while aromatic amines react with nitrous acid at low temperature (273-278 K) to form diazonium salts, a very important class of compounds used for synthesis of a variety of aromatic compounds.
