If the sum of bond orders of $\mathrm{O}_2^{-}$and $\mathrm{O}_2^{2-}$ is $x$, then bond order of $\mathrm{O}_2^{2+}$ will be

Identify the molecule / ion in which the ratio of $\sigma$ to $\pi$-bonds is $3: 2$

The sum of bond order of $\mathrm{O}_2^{+}, \mathrm{O}_2^{-}, \mathrm{O}_2$ and $\mathrm{O}_2^{2+}$ is equal to

Observe the following statements

Statement-I Hybridisation is not same in both $\mathrm{SF}_6$ and $\mathrm{BrF}_5$.

Statement-II $\mathrm{BrF}_5$ is square pyramidal while $\mathrm{SF}_6$ is octahedral in shape.

The correct answer is
