Solution

The correct option is A ${C l}_{2} O_{7}$
The formula for an oxide of chlorine with $C l$ in the oxidation state $+ 7$ is $C l_{2} O_{7}$ .
The oxidation number of $O$ is $- 2$ . Hence, the oxidation number of $C l$ in $C l_{2} O_{7}$ is $+ 7$ .
The oxidation number of $C l$ in $C l_{3} O_{5}, C l_{3} O_{7}$ and $C l_{2} O_{5}$ is $+ 3.33$ , $\frac{14}{3}$ and $+ 5$ respectively.
