Question

Molecular shapes of $S{F}_4,C{F}_4$ and $Xe{F}_4$ and the number of lone pairs on the central atom are respectively

• A. the same, with 1, 2 and 1
• B. the same, with 1, 0 and i
• C. different, with 0, 1 and 2
• D. different, with 1, 0 and 2
• E. the same, with 0, 0 and 1

Answer 1

Answer: (D)

Molecule	No. of bond angles	No. of lone pairs	Hybridisa-tion	Shape
$S{F}_4$	4	1	$s{p}^{3}d$	Irregular tetrahedral
$C{F}_4$	4	$-$	$s{p}^3$	tetrahedral
$Xe{F}_4$	4	2	$s{p}^3{d}^2$	square planar
