Options:

A) $ {{l}^{-}}>B{{r}^{-}}>C{{l}^{-}}>{{F}^{-}} $

B) $ {{l}^{-}}>B{{r}^{-}}<C{{l}^{-}}<{{F}^{-}} $

C) $ {{l}^{-}}<C{{l}^{-}}>{{F}^{-}}>B{{r}^{-}} $

D) $ {{l}^{-}}=B{{r}^{-}}>C{{l}^{-}}={{F}^{-}} $

Answer:

Correct Answer: A

Solution:

[a] Tendency to lose the electrons increases with the increase in the size of anion. (Valence shell electron(s) to be removed is farther from the nucleus in larger anion).
