Question

The basicity of aniline is less than that of cyclohexylamine. This is due to

$\(+ R$ ) effect of $\({- NH2}$ ) group

$\(-I$ ) effect of $\({- NH2}$ ) group

$\(-R$ ) effect of $\({-NH2}$ ) group

hyperconjugation effect.

Answer

$+ R$ effect of ${- NH2}$ group

Explanation

Solution

$\({-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.
