A) \[{{O}^{2-}}>{{F}^{-}}>O>F\]
B) \[{{O}^{2-}}>{{F}^{-}}>F>O\]
C) \[{{F}^{-}}>{{O}^{2-}}>F>O\]
D) \[{{O}^{2-}}>O>{{F}^{-}}>F\]
Correct Answer: A
Solution :
Atomic radius decreases on going from left to right in a period. Thus size of \[O>F\]. As \[{{O}^{2-}}\] and \[{{F}^{-}}\]are isoelectronic, therefore, size of \[{{O}^{2-}}>{{F}^{-}}.\]You need to login to perform this action.
