Question

Which products are expected from the disproportionation of hypochlorous acid?

• A. $HCl{O}_3$ and $C{l}_{2}O$
• B. $HCl{O}_2$ and $HCl{O}_4$
• C. $HCl$and $C{l}_{2}O$
• D. $HCl$ and $HCl{O}_3$

Answer 1

Answer: (D)

$HCl$ and $HCl{O}_3$

$3HClO\rightleftharpoons 2HCl+HCl{O}_3$

It is a disproportionation reaction of hypochlorous acid where the oxidation number of chlorine from $+1$ to $-1$

Higher is Oxidation no. more is effective nuclear charge, lesser is size.

The disproportionation of hypochlorous acid gives $HCl$ and $HCl{O}_3$.

Hence option D is correct.
