Question

$\text{MF}\text{+}{\text{XeF}}_{\text{4}}\to \text{A}$ ( ${\text{M}}^{\text{+}}$ = Alkali metal cation). The state of hybridisation of the central atom in $\text{A}$ and shape of the species are

• A. sp³d, TBP
• B. sp³d³, distorted octahedral
• C. sp³d³, pentagonal planar
• D. No compound formed at all

Answer 1

Answer: (C)

$\text{MF}+{\text{XeF}}_4\to {\text{M}}^{+}\left[{\text{XeF}}_5^{-}\right]$



Pentagonal planar ${\text{sp}}^{\text{3}}{\text{d}}^{\text{3}}$
