Given below are two statements:
Statement I: Primary aliphatic amines react with $HNO_2$ to give unstable diazonium salts.
Statement 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
Statement I is incorrect but Statement II is correct
B
Both Statement I and Statement II are correct
C
Both Statement I and Statement II are incorrect
D
Statement I is correct but Statement II is incorrect
Detailed Solution
Primary aliphatic amines react with $HNO_2$ to give highly unstable alkyl diazonium salts – Statement I is correct.
Aromatic diazonium salts are stable only at low temperature (273–278 K, i.e. 0–5 °C), not above 300 K – Statement II is incorrect.
So Statement I is correct but Statement II is incorrect.
