Sigma bond is stronger than the pi bond....

Sigma bond is stronger than the pi bond. Explain.

Text Solution

Verified by Experts

The strength of covalent bond depends upon the externt of the overlap. Greater the overlap, stronger is the bond. A sigma bond is formed by the axial overlap of the orbitas while pi bond by their sidewise or lateral overlap. Since the axial overlap is more effective than the sidewise overlap, greater energy is will be released in the axial overlap as compared to sidewise overlap. Therefore, sigma bond a stronger than the pi bond.
