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 $1$
• 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)

Different, with $1,0$ and $2$

Molecule	No. of bond angles	No. of lone pairs	Hybridisation	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
