Bond energies of sigma and pi-bonds are of the order of 264 kJ/mol and 347 kJ/mol respectively as bond energy of sigma bond is greater than pi bond. Related Theory A sigma bond is stronger because of the head to head overlapping, while a pi bond is weaker because of side to side overlapping. A sigma bond requires more energy to break than a pi bond does.
