Solution

The correct option is C
The O-O bond length in O2 $[A s F_{4}]$ is longer than $K O_{2} .$

As both carbon atoms are in different planes, all the four fluorine atoms are not in the same plane.

$O_{2} [A s F_{4}] = O_{2}^{+}, B . O = 2.5 K O 2 = O_{2}^{-}, B . O = 1.5 B o n d o r d e r \propto \frac{1}{B o n d l e n g t h}$

Greater the size of the halogen atoms, greater will be the repulsion and larger will be the bond angle.
