Vedclass · Answer

(B) The carbylamine test is a characteristic reaction given only by primary $(1^{\circ})$ amines,both aliphatic and aromatic.$(a)$ $N,N$-Dimethylaniline is a tertiary $(3^{\circ})$ amine.$(b)$ $2,4$-Dimethylaniline is a primary $(1^{\circ})$ aromatic amine.$(c)$ $N$-methyl-$o$-methylaniline is a secondary $(2^{\circ})$ amine.$(d)$ $p$-Methylbenzylamine is a primary $(1^{\circ})$ aliphatic amine.Since both $(b)$ and $(d)$ are primary amines,they will give a positive carbylamine test.

List-$I$ (Functional group)	List-$II$ (Functional group reagent)
$(a)$ Aliphatic Alcohol	$(i)$ Neutral ferric chloride test
$(b)$ $C_6H_5NH_2$	(ii) Azo dye test
$(c)$ $CH_3CH_2CHO$	(iii) Ceric ammonium nitrate test
$(d)$ Phenol	(iv) Tollen’s reagent test

$A$ positive carbylamine test is given by :-
$(a)$ $N,N$-Dimethylaniline
$(b)$ $2,4$-Dimethylaniline
$(c)$ $N$-methyl-$o$-methylaniline
$(d)$ $p$-Methylbenzylamine
