Question

Assertion electron gain in therapy of CL is more negative then F atom reason f is more negative than CL atom

Answer 1

Answer:

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.
