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

Options

A. `+R-` effect of `-NH_(2)` group
B. `-I-` efect of `-NH_(2)` group
C. `-R-` effect of `-NH_(2)` group
D. hyperconjugation effect

Answer

A

Explanation

Due to +R-effect of `-NH_(2)` group, `-NH_(2)` group donates the electron to the benzene ring, which is delocalised inside the ring resulting the less availability of lone pair of electron on N-atom for protonation. Therefore, aniline is less basic than cyclohexylamine.
