The reaction of an olefin with HBr can proceed by ionic as well as radical mechanism. The reaction in the presence of light takes place by radical mechanism, as

Options

Athe free energy of the reaction in radical mechanism is higher than in ionic mechanism
Bionic mechanism requires a catalyst while radical mechanism does not.
Cin the presence of light the activation energy of the reaction is lower than that for ionic mechanism.
Da radical reaction has very low activation energy as compared to that for the corresponding ionic reaction.

Correct answer

D. a radical reaction has very low activation energy as compared to that for the corresponding ionic reaction.
