####81. Regarding $F^{-}$and $Cl^{-}$which of the following statements is/are correct?
[1996]
(i) $Cl^{-}$can give up an electron more easily than $F^{-}$
(ii) $Cl^{-}$is a better reducing agent than $F^{-}$
(iii) $Cl^{-}$is smaller in size than $F^{-}$
(iv) $F^{-}$can be oxidized more readily than $Cl^{-}$
(a) (i) and (ii)
(b) (i), (ii) and (iv)
(c) (iii) and (iv)
(d) only (i)
Show Answer
Solution:
- (d) The halide ions act as reducing agents . $F^{-}$ ion does not show any reducing nature but $Cl^{-}$, $Br^{-} & I^{-}$ion act as reducing agents and their reducing nature is in increasing order
$ \xrightarrow[\text{ Reducing nature increases }]{Cl^{-} Br^{-} I^{-}} $
