Vedclass · Answer

(C) The Assertion is correct because a sigma $(\sigma)$ bond is formed by the axial overlap of atomic orbitals,which is more extensive than the lateral overlap that forms a pi $(\pi)$ bond. Therefore,the sigma $(\sigma)$ bond is stronger than the pi $(\pi)$ bond.The Reason is incorrect because atoms cannot rotate freely around a pi $(\pi)$ bond. The presence of a pi $(\pi)$ bond restricts rotation,as rotation would require breaking the lateral overlap of the $p$-orbitals.

Assertion : Sigma $(\sigma)$ is a strong bond,while pi $(\pi)$ is a weak bond.
Reason : Atoms rotate freely about pi $(\pi)$ bond.
