 Match column $\mathrm{I}$ with column $\mathrm{II}$ and select the correct answer.

$In{\mathrm{CH}}_2{\mathrm{SF}}_4;$ axial $\mathrm{FSF}=\mathrm{\beta };$ equatorial $\mathrm{FSF}$$=\mathrm{\alpha }$

Which of the following option is correct regarding $\mathrm{\alpha }$ and $\mathrm{\beta }?$

What is the correct order of bond angle of the following molecule?

Select the correct statement(s).

The incorrect order of the $\mathrm{O}-\mathrm{O}$ bond length in ${\mathrm{O}}_2, {\mathrm{H}}_2{\mathrm{O}}_2$ and ${\mathrm{O}}_3$ is

The correct order of $\mathrm{B}-\mathrm{F}$ bond length follows the sequence:

Consider the following statements:

($\mathrm{I}$) Percentage of $\mathrm{\sigma }$-bonding in $\mathrm{C}-\mathrm{O}$  bond follows the sequence $\mathrm{CO}<{\mathrm{CO}}_2<{\mathrm{CO}}_3^{2-}$.

($\mathrm{II}$) Relative strength of$\mathrm{\pi }$-bonding in ${\mathrm{BX}}_{ 3} (\mathrm{X}-\mathrm{F},\mathrm{Cl}, \mathrm{Br}, \mathrm{I})$, follows the sequence : ${\mathrm{BF}}_3={\mathrm{BCl}}_3<{\mathrm{BBr}}_3<{\mathrm{BI}}_3$.

($\mathrm{III}$) The correct order of bond length ($\mathrm{S}-\mathrm{O}$ ) follows the sequence : ${\mathrm{SO}}_3<{\mathrm{SO}}_4^{2-}$

$\left(\mathrm{IV}\right)$ $\mathrm{\pi }$-bond order follows the sequence : ${\mathrm{ClO}}_2^{-}<{\mathrm{ClO}}_3^{-}<{\mathrm{ClO}}_4^{-}$.

Using '$\mathrm{T}$' for 'True' and '$\mathrm{F}$' for 'False' statement in the given sequence, pick the correct set of codes.

In which of the following, all bonds are not equivalent?
