Consider the following statements about the oxides of halogens.

A. At room temperature, $\mathrm{OF}_2$ is thermally stable.

B. Order of stability of oxides of halogens is

$$ \mathrm{I}>\mathrm{Br}>\mathrm{Cl} . $$

C. $\mathrm{I}_2 \mathrm{O}_5$ is used in the estimation of CO .

D. $\mathrm{ClO}_2$ is used as a bleaching agent.

The correct statements are,

$$ \begin{aligned} \mathrm{XeF}_4+\mathrm{O}_2 \mathrm{~F}_2 & \longrightarrow X+\mathrm{O}_2 \\ X+\underset{(1 \text { mole })}{\mathrm{H}_2 \mathrm{O}} & \longrightarrow Y+2 \mathrm{HF} \end{aligned} $$

The shapes of molecules of $X$ and $Y$ respectively are

Among the following the incorrect statement about transition metals is

$$ \text { Match the following. } $$

$$ \begin{array}{llll} \hline & \begin{array}{l} \text { List-I } \\ (\text { Complex }) \end{array} & & \begin{array}{l} \text { List-II } \\ \text { (Spin only magnetic } \\ \text { moment) } \end{array} \\ \hline \text { A. } & {\left[\mathrm{CoF}_6\right]^{3-}} & \text { I. } & 0 \\ \hline \text { B. } & {\left[\mathrm{Co}\left(\mathrm{C}_2 \mathrm{O}_4\right)_3\right]^{3-}} & \text { II. } & \sqrt{24} \\ \hline \text { C. } & {\left[\mathrm{FeF}_6\right]^{3-}} & \text { III. } & \sqrt{8} \\ \hline \text { D. } & {\left[\mathrm{Mn}(\mathrm{CN})_6\right]^{3-}} & \text { IV. } & \sqrt{35} \\ \hline & & \text { V. } & \sqrt{15} \\ \hline \end{array} $$

The correct answer is
