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.

    A
    The atomic number of fluorine is less than that of chlorine
    B
    Fluorine being the first member of the family behaves in an unuseual manner
    C
    Chlorine can accommodate an electron better than fluorine by untilising its vacant `3d` orbital
    D
    Small size, high electron density and an increases electron repulsion make addition of an electron to fluorine less favourable than that in the case of chlorine
