    What products are expected from the disproportionation reaction 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 \[HCl{{O}_{3}}\]

    Correct Answer: D

    Solution :

     In disproportionation reactions, the same element is oxidised as well as reduced. In \[\text{HOCl,}\]the oxidation state of \[\text{Cl}\] is \[+\,1.\] In \[\text{HCl}{{\text{O}}_{\text{3}}}\text{,C}{{\text{l}}_{\text{2}}}\text{O,}\,\text{HCl}{{\text{O}}_{\text{2}}}\text{,}\,\text{HCl}{{\text{O}}_{\text{4}}}\]and \[\text{HCl,}\]the oxidation states of Cl are \[+\,5,+\,1,+\,3,+\,7\]and\[-1\] respectively. Thus, the disproportionation products are \[\text{HCl}\] and \[\text{HCl}{{\text{O}}_{3}}.\]
