Vedclass · Answer

(D) The bond energy is inversely proportional to the extent of lone pair-lone pair repulsion between the bonded atoms. As the number of lone pairs (non-bonded electrons) on the bonded atoms increases,the repulsion between them increases,which weakens the bond and decreases the bond energy. Comparing the number of non-bonded electrons: $C-C$ has $3+3 = 6$ non-bonded electrons (in the provided structure). $N-N$ has $4+4 = 8$ non-bonded electrons (in the provided structure). $H-H$ has $0$ non-bonded electrons. $O-O$ has $6+6 = 12$ non-bonded electrons (in the provided structure). Since the $O-O$ bond has the highest number of non-bonded electrons,the inter-electronic repulsion is maximum,making the $O-O$ bond the weakest with the lowest bond energy.

Which of the following bonds has the lowest bond energy?
