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 :

1. Statement I is incorrect but Statement II is correct.

2. Both Statement I and Statement II are correct.

3. Both Statement I and Statement II are incorrect.

4. Statement I is correct but Statement II is incorrect.

Best answer

Answer: 4. Statement I is correct but Statement II is incorrect.

Key idea: diazonium salts of aliphatic amines are unstable; aromatic ones are stable only at low temperature.

  • Statement I: aliphatic primary amines with \(\mathrm{HNO_2}\) give unstable diazonium salts that decompose to alcohols and \(\mathrm{N_2}\). Correct.
  • Statement II: aromatic diazonium salts are stable only at 273-278 K (resonance helps) and decompose above about 283 K. Stating stable above 300 K is incorrect.

Option 4.
