Question

The shape and hybridisation of some xenon oxyfluorides are given. Choose the wrong set.

• A. $XeOF_2 T$ - Shape - $sp^3d$
• B. $XeOF_4$ - Square pyramidal-$sp^3d^2$
• C. $XeO_2F_2$ - Distorted trigonal bipyramidal-$sp^3d$
• D. $XeO_3F_2$ - Octahedral - $sp^3d$

Answer 1

Answer: (D)

$XeO_3F_2$ - Octahedral - $sp^3d$

Answer 2

The structure of $XeO _{3} F _{2}-$ No. of lone pair of $Xe =0$ and $no$. of bond pair $=5$ Hybridisation of $X e=s p^{3} d$ Hence, shape of $XeO _{3} F _{2}$ should be trigonal bipyramidal and not octahedral.
