Q. The species which does not undergo disproportionation reaction is :
A) ClO₃⁻
B) ClO⁻
C) ClO₂⁻
D) ClO₄⁻
Explanation
[Solution by Dr. Abubacker] Disproportionation needs an element in an intermediate oxidation state. In ClO₄⁻ chlorine is already at its maximum (+7), so it cannot be oxidised further and cannot disproportionate; ClO⁻ (+1), ClO₂⁻ (+3) and ClO₃⁻ (+5) can. Answer (4).
