Which of the following has a square pyramidal shape?

Options

A. `XeOF_4`
B. `XeO_3F_2`
C. `XeOF_2`
D. `XeO_2F_2`

Answer

A

Explanation

For square pyramidal shape, the SN of central atom should be `5+1=6`. In `XeO_2F`, the SN of central `Xe` is `4+1=5`. In `XeOF_2`, the SN of central `Xe` is `3+2=5`. In `XeO_3F_2`, the steric number of central `Xe` is `5+0=5`. In `XeOF_4`, the SN of central `Xe` is `5+1=6`. Thus, it has square pyramidal shape.
