Out of `sigma and pi` -bonds, which one is stronger and why ?

1.	Out of `sigma and pi` -bonds, which one is stronger and why ?
Answer» `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 sideway overlapping which is small .
