Given below are two statements Statement I: Primary aliphatic amines react with HNO2HNO_2 to give unstable diazonium salts. Statement II: Primary aromatic amines react with HNO2HNO_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

Statement I is correct but Statement II is incorrect

B

Statement I is incorrect but Statement II is correct

C

Both Statement I and Statement II are correct

D

Both Statement I and Statement II are incorrect

Step-by-Step Solution

Primary aliphatic amines react with nitrous acid (HNO2HNO_2) to form highly unstable aliphatic diazonium salts, which decompose to form alcohols and nitrogen gas. Primary aromatic amines react with HNO2HNO_2 to form benzene diazonium salts, which are stable only at low temperatures (0-5°C or 273-278 K). They are not stable above 300 K. Thus, Statement I is correct and Statement II is incorrect.
