Electron gain enthalpy of fluorine is less than that of chlorine - explain.

Text Solution

Verified by Experts

Fluorine atom is small in size and suffers with interelectronic repulsions between seven valence electrons. The added electron experiences much repulsion on smaller F. Hence its electron gain enthalpy is less.
