Which of the following compound possesses the $$C-H$$ bond with the lowest bond dissociation energy?

AToluene
Correct Answer
BBenzene
Cn-pentane
D2,2-dimethyl propane

Solution

Toluene possesses the $$C−H$$ bond with the lowest bond dissociation energy.

The $$C−H$$ bond of the methyl group is in hyperconjugation with benzene nucleus.

Hence, it is easy to break. Hence, it has the lowest bond dissociation energy.

Hence, the correct option is A.
