Vedclass · Answer

(B) The basicity of amines depends on the availability of the lone pair of electrons on the nitrogen atom. In $C_6H_5NH_2$ (aniline),the lone pair is delocalized into the benzene ring due to resonance,reducing its availability. In $O_2N-C_6H_4-NH_2$,the $-NO_2$ group is a strong electron-withdrawing group,which further decreases the electron density on nitrogen. In $C_6H_5NHCOCH_3$,the lone pair is involved in resonance with the carbonyl group $(C=O)$,making it less available. In $C_6H_{11}NH_2$ (cyclohexylamine),the nitrogen is attached to an $sp^3$ hybridized carbon atom. There is no resonance,and the alkyl group shows a $+I$ effect,which increases the electron density on the nitrogen atom,making it the strongest base among the given options.
