Question

The geometrical shapes of XeF₅⁺ , XeF₆ and XeF₈^2– respectively are

• A. Trigonalbipyramidal , octahedral and square planar
• B. Square based pyramidal , distorted octahedral and octahedral
• C. Planar pentagonal , octahedral and square anti prismatic
• D. Square based pyramidal, distorted octahedral and square anti prismatic

Answer 1

Answer: (D)

Square based pyramidal, distorted octahedral and square anti prismatic

Answer 2

H of XeF₅⁺ = $\frac{1}{2}$ ( 8 + 5 – 1+ 0) = 6 Ž sp³d²

Square based pyramidal

H of XeF₆ = $\frac{1}{2}$ (8 + 6 – 0 + 0) = 7 Ž sp³d³

distorted octahedral
