Question:

The reaction in which the hybridisation of the underlined atom is affected is :-

1. $\underline{\mathrm{NH}_{3}} \stackrel{\mathrm{H}^{*}}{\longrightarrow}$

2. $\underline{\mathrm{XeF}}_{4}+\mathrm{SbF}_{5} \rightarrow$

3. $\mathrm{H}_{2} \underline{\mathrm{S}} \mathrm{O}_{4}+\mathrm{NaCl} \stackrel{420 \mathrm{~K}}{\longrightarrow}$

4. $\mathrm{H}_{3} \mathrm{PO}_{2} \stackrel{\text { Dispropartionation }}{\longrightarrow}$

Correct Option: , 2

Solution:

$\mathrm{XeF}_{4}+\mathrm{SbF}_{5} \rightarrow\left[\mathrm{XeF}_{3}\right]^{+}\left[\mathrm{SbF}_{6}\right]$
