Vedclass · Answer

(A) The electron gain enthalpy (or electron affinity) generally becomes less negative as we move down the group from $Cl$ to $I$. However,$F$ has an exceptionally low electron gain enthalpy compared to $Cl$ due to its small size and high inter-electronic repulsion between the incoming electron and the existing electrons in the $2p$ subshell. Therefore,the correct order is $F  Br > I$.
