Why sigma bond is stronger than pi bond

Sigma bonds are formed by head on overlap of atomic orbitals. Whereas pi bonds are formed in addition to sigma bonds by sideways overlapping of atomic orbitals. Since in formation of a sigma bond, the orbitals are along inter nuclear axis this results in more effective orbital overlap as compared to when pi bonds are formed as they are perpendicular to the internuclear axis. This significant difference in orbital overlap results in sigma bond being stronger than the pi bond.

Sigma Bond is Stronger than Pi Bond , Because length of sigma bond is less than pi bond. Thus force of attraction is greater in sigma Bond as compared to pi bond

In sigma bond linear overlapping occurs while in pi bond parallel overlapping occurs.
