Which of the following bonds have lowest bond energy?

AC-C
BN-N
CH-H
DO-O
Correct Answer

Solution

As you can see, the atoms are covalently bonded, smaller the atom, greater the repulsion, which is due to the presence of lone pairs causing the bond to be relatively weaker.

More the no.of lone pairs, More the repulsion force.

O−O possess lowest Bond energy, as it has the maximum no.of non-bonded electrons.

Hence, the correct option is D.
