There is greater overlapping in sigma bond that means electrons come more closer than in pi bond. Then there should be greater inter ionic repulsions. Still why sigma bonds are stronger than pi bonds?

DEAR DEEKSHA,


THE REASON IS:


Because sigma bonds contain hybridized atomic orbitals and pi bonds do not, the sigma bond is stronger in the sense that it has more area to allow for the constructive interference of another sigma bond. Also, sigma bonds are stronger because they possess less energy than pi bonds. This can be depicted on a typical energy level diagram for the molecular orbitals. The hybridized atomic orbitals will be at a lower energy level than the remaining p-orbital, which is perpendicular to the molecule's plane.

does it mean that the electrons can occupy a larger amount of space when there is a greater overlap? and hence make the bond stronger(more stable)???????
