Question

Why is there equivalent electron gain in the dissociation of chloromethane?

Answer 1

equivalent electron gain in the dissociation of chloromethane is

Answer 2

Explanation:

The negative electron gain enthalpy of fluorine is less than that of chlorine. It is due to small size of fluorine atom. As a result, there are strong interelectronic repulsions in the relatively small 2p orbitals of fluorine and thus, the incoming electron does not experience much attraction
