Detailed Solution

At room temperature, ${OF}_{2}$ is thermally stable. It has a low boiling point due to which, at a high temperature, it becomes unstable.
Order of stability of oxides of halogens is $I > Cl > Br$
$I_{2} O_{5}$ is used for the determination of carbon monoxide $(CO)$ in the gaseous condition and gives carbon dioxide $({CO}_{2})$ and solid iodine $(I_{2})$ .
${ClO}_{2}$ is used as a bleaching agent
