Its unique property in chlorine.Actually flourine should be the answer according to the periodic table., but it isn't so. I would happy if anyone knew the reason. F < C l > B r > I . \boxed{F<Cl>Br>I}.

Because flourine is too small and the incoming electron faces much repulsion from the flourine atom.That's why electron gain enthalpy of Cl is higher than F.

Chlorine (Cl) has more negative electron gain enthalpy than fluorine (F). F has less negative electron gain enthalpy because in it the added electron goes to the smaller energy level (n=2) and hence suffers significant repulsion from the electrons already present in this shell.
