Answer:

The electron gain enthalpy values of halogens become more negative in the order F>Cl>Br>I. ... However the electron gain enthalpy of F is less negative than of Cl because of its small size. The additional electron in case of F will be added to the 2p orbital while in case of Cl it will go in the 3p orbital.
