Question

Which of the following shape are not possible for possible value of 'n' in $Xe{F}_n$ molecule?

• A. Linear
• B. Square planar
• C. Trigonal planar
• D. Capped octahedral

Answer 1

Answer: (C)

In $Xe{F}_n$ , the possible values of 'n' is 2, 4, 6, then compound should be $Xe{F}_2$ $(s{p}^{3}d$ linear), $Xe{F}_4$ ( $s{p}^3{d}^2$ square planar) $Xe{F}_6$ ( $s{p}^3{d}^3$ capped octahedral) so in this case trigonal planar molecule is not possible.
