Vedclass · Answer

(C) The electron gain enthalpy is the energy released when an electron is added to a neutral gaseous atom.For halogens,the expected trend based on size is $F > Cl > Br > I$.However,due to the very small size of the fluorine atom,the inter-electronic repulsions are high,which makes the incoming electron experience less attraction compared to chlorine.Therefore,the absolute value of electron gain enthalpy for chlorine is higher than that of fluorine.The correct order of the absolute value of electron gain enthalpy is $Cl > F > Br > I$.

The absolute value of the electron gain enthalpy of halogens satisfies which of the following orders?
