Out of σ and π-bonds, which bond is stronger and why?

Text Solution

Verified by Experts

`sigma` - bond is stronger. This is because `sigma` - bond is formed by head-on overlapping of atomic orbitals and, therefore, the overlapping is large. `pi` - bond is formed by sidewise overlapping which is small.
