Aniline and cyclohexylamine both hane NH2 group and six carbon ring but the difference in basicity lies in a manner that aniline is a weak base then cyclohexylamine because aniline is an aromatic ring, because of the electron-withdrawing effect of the phenyl group aniline is a weak base.The unshared ellectron pair of electron on nitrogen atom is present in conjucation with the benzene ring and becomes less available for protonation because of resonance.
