Question

The basicity of the cyclohexylamine is more than that of aniline because of (A) resonance (B) hyper conjugation effect (C)  +R text- effect of -NH2 group (D)  -R text- effect of -NH2 group

Tardigrade Admin · Accepted Answer

-NH2 has +R -effect, it donates electrons to the benzene ring. As a result, the lone pair of electrons on the N-atom get delocalised over the benzene ring and less available for protonation. Thats why cyclohexylamine is more basic than aniline.

resonance

hyper conjugation effect

$+ R -$ effect of $- N H_{2}$ group

$- R -$ effect of $- N H_{2}$ group

$- N H_{2}$ has $+ R$ -effect, it donates electrons to the benzene ring. As a result, the lone pair of electrons on the N-atom get delocalised over the benzene ring and less available for protonation. Thats why cyclohexylamine is more basic than aniline.

+R- effect of −NH2​ group

−R- effect of −NH2​ group

−NH2​ has +R -effect, it donates electrons to the benzene ring. As a result, the lone pair of electrons on the N-atom get delocalised over the benzene ring and less available for protonation. Thats why cyclohexylamine is more basic than aniline.
