Vedclass · Answer

(B) primary $(1^{\circ})$ amine is a compound where the nitrogen atom is attached to only one alkyl or aryl group,represented by the general formula $R-NH_2$.$1$. Ethyl methyl propyl amine: $CH_3-CH_2-N(CH_3)-CH_2-CH_2-CH_3$. The nitrogen is attached to three alkyl groups,so it is a $3^{\circ}$ amine.$2$. Hexamethylene diamine: $H_2N-(CH_2)_6-NH_2$. Each nitrogen atom is attached to only one carbon atom,so it is a $1^{\circ}$ amine.$3$. Diphenyl amine: $Ph-NH-Ph$. The nitrogen is attached to two phenyl groups,so it is a $2^{\circ}$ amine.$4$. $N,N$-Dimethyl aniline: $Ph-N(CH_3)_2$. The nitrogen is attached to one phenyl group and two methyl groups,so it is a $3^{\circ}$ amine.Therefore,Hexamethylene diamine is the primary amine.
