Question

Why the o-o single bond weaker than the s-s single bond even though the o=o double bond is stronger than the s=s double bond?

Answer 1

》because due to small size the lone pair of electrons on oxygen atoms repel the bond pair of O-O bond to a greater extent than the lone pair of electrons on the sulfur atoms in S-S bond....as a result S-S bond (bond energy=213 kj/mole)is much more stronger than O-O(bond energy = 138 kj/mole) bond .
