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

Text Solution

Verified by Experts

Due to small size of F atom and compact 2p orbitals there are strong interelectronic repulsions in the relatively smaller 2p orbitals of fluorine. So the incoming electron does experience more repulsion in F than in Cl.
