Question

Which of the following explanation is incorrect for $ClO _{4}^{-}$species?

• A. $ClO _{4}^{-}$shows disproportionation reaction
• B. $ClO _{4}^{-}$does not show disproportionation reaction
• C. $The$ oxidation number of $Cl$ is $+7$ in $ClO _{4}^{-}$
• D. $ClO _{4}^{-}$is basic in nature

Answer 1

Answer: (A)

$ClO _{4}^{-}$does not show disproportionation reaction because oxoanion of chlorine is present in its highest oxidation state, i.e. $+7$, so it does not further increase its oxidation number.
