The correct answer is:
$\mathrm{Cl}_{2} \mathrm{O}$
$\mathrm{Ca}(\mathrm{OCl}) \mathrm{Cl} \longrightarrow \mathrm{Ca}^{2+}+-\mathrm{OCl}+\mathrm{Cl}^{-}$
-OCl (Hypochlorite ion) is anion of the acid HOCl which on dehydration gives $\mathrm{Cl}_{2} \mathrm{O}$.
$2 \mathrm{HOCl} \longrightarrow \mathrm{H}_{2} \mathrm{O}+\mathrm{Cl}_{2} \mathrm{O}$
-OCl (Hypochlorite ion) is anion of the acid HOCl which on dehydration gives $\mathrm{Cl}_{2} \mathrm{O}$.
$2 \mathrm{HOCl} \longrightarrow \mathrm{H}_{2} \mathrm{O}+\mathrm{Cl}_{2} \mathrm{O}$
