\($-I$\) effect of \(${- NH2}$\) group
\($-R$\) effect of \(${-NH2}$\) group
\(${-NH2}$\) has a \($+R$\) effect, it donates electrons to the benzene ring. As a result of resonance, the lone pair of electrons on the N atom gets delocalized over the benzene ring and thus it is less readily available for protonation. Hence aniline is a weaker base than cyclohexyl amine.
