Q. Given below are two statements: Statements I: Primary aliphatic amines react with $HNO_2$ to give unstable diazonium salts. Statements II: Primary aromatic amines react with $HNO_2$ 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:
A) Statements I is incorrect but Statements II is correct.
B) Both Statements I and Statements II are correct
C) Both Statements I and Statements II are incorrect.
D) Statements I is correct but Statement II is incorrect.
Explanation
[Solution] Aliphatic diazonium salts are highly unstable. Aromatic diazonium salts are stable only at low temperature (273-278 K), not above 300 K, so Statement II is incorrect. Answer (4).
