Q No : 16 Cyclohexyl amine is a stronger base than aniline. justify
Ans :
1.This is because lone pair of electrons on the N- atom of aniline is declocalized over the benzene ring.

2. However in cyclhexyl amine the lone pair of electrons on N- atom are not conjugated and are therefore more readily available for donation or protonation than that on the N- atom of aniline.

3.Further N- atom in aniline is sp2 hybridized and in cyclohexyl amine it is sp3 hybridized.

4. Since sp2 has greater electronegative character than sp3, the electrons are more tightly held in case of aniline

whereas they are losely held and readily available for protonation in cyclohexyl amine.
