Vedclass · Answer

(A) Based on the classification of amines:$(A)$ $CH_3CH_2CH_2CH_2NH_2$ contains the $-NH_2$ group attached to one alkyl group,making it a primary amine $(1^\circ)$. Thus,$(A) \rightarrow (v)$.$(B)$ $(CH_3CH_2)_2NH$ contains the $-NH-$ group attached to two alkyl groups,making it a secondary amine $(2^\circ)$. Thus,$(B) \rightarrow (i)$.$(C)$ $(CH_3)_3N$ has the nitrogen atom attached to three alkyl groups,making it a tertiary amine $(3^\circ)$. Thus,$(C) \rightarrow (ii)$.$(D)$ $C_6H_5NH_2$ (Aniline) is an amine where the nitrogen is directly attached to a benzene ring,making it an aromatic amine. Thus,$(D) \rightarrow (iii)$.Therefore,the correct sequence is $A-(v), B-(i), C-(ii), D-(iii)$.

Column $I$	Column $II$
$(A)$ $CH_3CH_2CH_2CH_2NH_2$	$(i)$ Secondary amine
$(B)$ $(CH_3CH_2)_2NH$	$(ii)$ Tertiary amine
$(C)$ $(CH_3)_3N$	$(iii)$ Aromatic amine
$(D)$ $C_6H_5NH_2$	$(iv)$ Quaternary ammonium salt
	$(v)$ Primary amine
