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 COMPARE TO PI BOND.

The extent of overlapping in case of sigma bond is maximum as compared to the case of pi bond. So the sigma bond is comparatively stronger than the pi bond.

Pi bonds are usually weaker than sigma bonds. Quantum mechanics says this is because the orbital paths are parallel so there is much less overlap between the p-orbitals. Pi bonds happen when two atomic orbitals are in contact through two areas of overlap

Sigma bonds are strong

Sigma bonds are stronger bcoz they overlap to greater extent than atomic orbitals forming pi bonds and also length of sigma bonds is less.. Sigma bonds are formed by head on overlaps while pi bonds are formed by side on overlapping.
