A) +R-effect of\[-N{{H}_{2}}\] group
B) \[-I\]effect of\[-N{{H}_{2}}\] group
C) -R effect of \[-N{{H}_{2}}\] group
D) hyperconjugation effect
Correct Answer: A
Solution :
\[-N{{H}_{2}}\] has +R effect, it donates electrons to the benzene ring. As a result, the lone pair of electron 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 cyclohexylamine.
