Sigma bonds are stronger than pi bonds due to the following reasons:

1. Overlap Extent: Sigma bonds are formed by the head-on overlapping of atomic orbitals, which creates a strong bond between the two atoms. On the other hand, pi bonds are formed by the lateral or sideways overlapping of atomic orbitals, which is not as effective, resulting in a weaker bond.

2. Electron Distribution: In a sigma bond, the electron density is concentrated along the line joining the two bonded atoms, which makes the bond stronger. In a pi bond, the electron density is spread out above and below the plane of the atoms, making the bond weaker.

3. Number of Bonds: A single bond is always a sigma bond, while a double bond is composed of one sigma bond and one pi bond, and a triple bond is composed of one sigma bond and two pi bonds. Therefore, sigma bonds are more common and stronger than pi bonds.

4. Rotation: Sigma bonds allow free rotation of atoms around the bond axis, while pi bonds restrict this rotation. This makes sigma bonds more stable and stronger than pi bonds.
