Question

p-Chloroaniline and anilinium hydrogen chloride cannot be distinguished by:

• A. Sandmeyer reaction
• B. Carbylamine reaction
• C. Hinsberg's reaction
• D. $AgN{O}_3$

Answer 1

Answer: (A), (B), (C)

Hinsberg's reaction

p-Chloroaniline and anilinium hydrogen chloride can be distinguished by $AgN{O}_3$. Anilinium hydrogen chloride will give white ppt of $AgCl$ on reaction with $AgN{O}_3$
but p-chloronoaniline will not react with it because $Cl$ is directly attached to benzene nucleus.
