Q. The correct order of radii of $F^{-} F^{-}, O$ and $O^{2-}$ is
MHT CET
MHT CET 2021
A
$O^{2-}>F^{-}>F>O$
B
$F^{-}>O^{2-}>F>O$
C
$O^{2-}>O>F^{-}>F$
D
$O^{2-}>F^{-}>O>F$
Solution:
Radii of the given species vary in the order.
$O^{2-}>F^{-}>O>F$
The size of the anion is larger than their parent atom. Also, the more the nuclear charge, the lesser is the size.
