MCQ
The oxidation number of chlorine is maximum in $.........$
  • A
    $\ce{HOCl}$
  • B
    $ \mathrm{Cl}_2 \mathrm{O}_6 $
  • $ \mathrm{KClO}_4 $
  • D
    $\mathrm{NaClO}_3 $

Answer

Correct option: C.
$ \mathrm{KClO}_4 $
The oxidation numbers of chlorine in $\ce{HOCl},\   \mathrm{Cl}_2 \mathrm{O}_6  ,\  \mathrm{KClO}_4 $
and $\ce{NaClO3}$​ are $+1, +6, +7$ and $+5$ respectively. Hence, the oxidation number of chlorine is maximum in $ \mathrm{KClO}_4 $
