Question

Out of the following species, which has planar structure?

• A. $N{H}_4^{+}$
• B. $C{F}_4$
• C. $Xe{F}_4$
• D. $CC{l}_4$

Answer 1

Answer: (C)

$Xe{F}_4$

$N{H}_4^{+},C{F}_4,CC{l}_4$ are tetrahedral in shape while $Xe{F}_4$ has square bipyramidal geometry and due to the presence of two lone pair of electrons occupying the axial positions, it exists as square planar structure.

$C$ is correct.
