Question

Which structure for $XeO_{3} \, and XeF_{4}$ are consistent with the VSEPR model?

• A. $XeO_{3},$ trigonal pyramidal; $XeF_{4,}$ square planar
• B. $XeO_{3,}$ trigonal planar; $XeF_{4}$ square planar
• C. $XeO_{3,}$ trigonal pyramidal; $XeF_{4,}$ tetrahedral
• D. $XeO_{3,}$ tirgonal planar; $XeF_{4,}$ tetrahedral

Answer 1

Answer: (A)

$XeO_{3}$ ; 3$\sigma$ bond and 1 lone pair; $sp^{3}$ hybridisation
Shape trigonal pyramidal
$XeF_{4} ; $ 4 $\sigma$ bonds, 2 lone pairs; $sp^{3}d^{2}$ hybridisation
Shape square planar
