Which one of the following is planar ?

A

`XeF_4`

B

`XeO_4`

C

`XeO_3F`

D

`XeO_3F_2`

Text Solution

Verified by Experts

The correct Answer is:
A
Structure of `XeF_4` is as follows

It involves `sp^3d^2` hybridisation in Xe-atom . The molecules has square planar structure . Xe and four F-atoms are coplanar . The lone pairs are present on axial positions, minimise electron pair repulsion.

Square planar complexes are generally formed by d^(8) ions with strong field ligands. The crystal field splitting is larger for second and third row transition elements and for more highly charged species. All the complexes having 4d^(8)" and "5d^(8) configuration are mostly square including those with weak field ligands such halide ions.
