Vedclass · Answer

(A) The basic strength of an oxoanion is inversely proportional to the oxidation state of the central atom $(Cl)$.Higher oxidation state of the central atom leads to greater acidic nature and lower basic strength.Calculating the oxidation state of $Cl$ in each species:$ClO_2^{-}: x + 2(-2) = -1 \implies x = +3$$ClO_3^{-}: x + 3(-2) = -1 \implies x = +5$$ClO_4^{-}: x + 4(-2) = -1 \implies x = +7$Since the order of oxidation states is $ClO_4^{-} (+7) > ClO_3^{-} (+5) > ClO_2^{-} (+3)$,the order of acidic nature is $ClO_4^{-} > ClO_3^{-} > ClO_2^{-}$.Therefore,the order of basic strength is the reverse: $ClO_2^{-} > ClO_3^{-} > ClO_4^{-}$.Thus,option $(A)$ is the correct answer.

What is the order of relative basic strength of $ClO_2^{-}, ClO_3^{-}, ClO_4^{-}?$
