\(\mathrm{XeF}_4\) is square planar while \(\mathrm{XeF}_6\) has a distorted octahedral structure. What is the correct explanation for this observation?

  1. A Both molecules have one lone pair of electrons
  2. B Both molecules have two lone pairs of electrons
  3. C \(\mathrm{XeF}_4\) does not have any lone pair of electrons; \(\mathrm{XeF}_6\) has one lone pair of electrons on \(\mathrm{Xe}\)
  4. D \(\mathrm{XeF}_4\) has two lone pairs of electrons on \(\mathrm{Xe}^2 \mathrm{XeF}_6\) has one lone pair of electrons on Xe

Answer & Solution

Correct Answer

(D) \(\mathrm{XeF}_4\) has two lone pairs of electrons on \(\mathrm{Xe}^2 \mathrm{XeF}_6\) has one lone pair of electrons on Xe

Step-by-step Solution

Detailed explanation

\(\mathrm{XeF}_4\) is square planar and \(s p^3 d^2\)-hybridised. \(4 \sigma+2 l p=6\)-hybrid orbital \(s p^3 d^2\)-hybridisation \(\mathrm{XeF}_6\) has distorted octahedral structure and \[s p^3 d^3 \text {-hybridised. } \] \(6 \sigma+1 l p=7\)-hybrid orbital…
