Chlorine water on standing loses its colour and forms

A
$HCl$ only
B
$HCl$ and $HClO_2$
✓
$HCl$ and $HOCl$
D
$HOCl$ and $HOCl_2$

✓

Answer

Correct option: C.

$HCl$ and $HOCl$

c
$\begin{align}
\,\,+I \\
\Rightarrow \,\,Cl{{O}^{-}} \\
B.O.\,=\,1.0 \\
Hyb.\,\,of\,Cl\,:\,s{{p}^{3}} \\
\end{align}$ $\begin{align}
\,+III\,\,\,\,\, \\
\,\,ClO_{2}^{-} \\
B.O.\,=\,1.5 \\
Hyb.\,\,of\,Cl\,:\,s{{p}^{3}} \\
\end{align}$

$\begin{align}
+V\,\,\,\,\, \\
\,\,ClO_{3}^{-} \\
B.O.\,=\,1.67 \\
Hyb.\,\,of\,Cl\,:\,s{{p}^{3}} \\
\end{align}$ $\begin{align}
\,+VII\,\,\,\,\, \\
