Question

Which of the following has a square pyramidal shape?

• A. ${\mathrm{XeOF}}_2$
• B. ${\mathrm{XeO}}_3{\mathrm{F}}_2$
• C. ${\mathrm{XeOF}}_4$
• D. ${\mathrm{XeO}}_2{\mathrm{F}}_2$

Answer 1

The correct option is C

${\mathrm{XeOF}}_4$

Explanation for the correct option:

(c ) ${\mathrm{XeOF}}_4$

• 
• ${\mathrm{XeOF}}_4$ has square pyramidal geometry.
• Hence this option is correct

Explanation for the incorrect options:

(a) ${\mathrm{XeOF}}_2$

• ${\mathrm{XeOF}}_2$ has trigonal bipyramidal structure
• 
• Thus, this option is incorrect.

(b) ${\mathrm{XeO}}_3{\mathrm{F}}_2$

• ${\mathrm{XeO}}_3{\mathrm{F}}_2$ is${\mathrm{sp}}^3\mathrm{d}$ and its structure is trigonal bipyramidal
• 
• Thus, this option is incorrect.

(d) ${\mathrm{XeO}}_2{\mathrm{F}}_2$

• ${\mathrm{XeO}}_2{\mathrm{F}}_2$has trigonal biplanar or seesaw geometry
• 
• Thus, this option is incorrect.

Hence the correct option is (c ) ${\mathrm{XeOF}}_4$
