\($+ R$\) effect of \(${- NH2}$\) group
\($-I$\) effect of \(${- NH2}$\) group
\($-R$\) effect of \(${-NH2}$\) group
- hyperconjugation effect.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
\(${-NH2}$\) has a \($+R$\) effect, it donates electrons to the benzene ring. As a result of resonance, the lone pair of electrons 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 cyclohexyl amine.

Classification of Organic Compounds
Organic Compounds can be classified into:
Classification based on the structure:
The classification of organic compounds is based on structure such as:
- Acyclic or open chain compounds - Acyclic compounds are just opposite to cyclic compounds because their molecules don’t form any ring. It is called open-chain compounds because they have a linear structure.
- Cyclic or closed chain compounds - Cyclic compounds are also known as “Ring compounds.”
