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
