Question

Give one chemical test to distinguish between Aniline and benzylamine.

Answer 1

Can be distinguished by their reaction with the help of ${HNO}_2$. Benzylamine resees with ${HNO}_2$ to form unstable diazonium salt, with the evolution of

$N_2$ gas. $C_6{H}_5{CH}_2{NH}_2+{HNO}_2⟶C_6{H}_5{CH}_2+HCL+N_2\uparrow$

$C_6{H}_5{NH}_2+{HNO}_2⟶C_6{H}_5{N}_2^{+}{CL}^{-}+Nacl+H_{2}O$
