Consider the following reactions A + Little amount NaCl + H_2 SO_4 → CrO_2 Cl_2+ Side Products; CrO_2 Cl_2( Vapour )+ NaOH → B + NaCl + H_2 O; B +…
Consider the following reactions
$$\mathrm{A}+\underset{\substack{\text { Little } \\ \text { amount }}}{\mathrm{NaCl}}+\mathrm{H}_2 \mathrm{SO}_4 \rightarrow \mathrm{CrO}_2 \mathrm{Cl}_2+\text { Side Products }
$$
$$\begin{aligned}
& \mathrm{CrO}_2 \mathrm{Cl}_2(\text { Vapour })+\mathrm{NaOH} \rightarrow \mathrm{~B}+\mathrm{NaCl}+\mathrm{H}_2 \mathrm{O} \\
& \mathrm{~B}+\mathrm{H}^{+} \rightarrow \mathrm{C}+\mathrm{H}_2 \mathrm{O}
\end{aligned}
$$
The number of terminal ' O ' present in the compound ' C ' is $\displaystyle \_\_\_\_$.
