Question

The pair of species having identical shapes for molecules of both species is:

• A. $Xe{F}_2,C{O}_2$
• B. $B{F}_3,PC{l}_3$
• C. $P{F}_5,I{F}_5$
• D. $C{F}_4,Si{F}_4$

Answer 1

Answer: (A), (D)

The correct options are
A $Xe{F}_2,C{O}_2$
D $C{F}_4,Si{F}_4$

$Xe{F}_2$ - sp${}^3$d hybridization with 2 bond pairs, 3 lone pairs and linear structure.
$C{O}_2$ is linear molecule with sp hybridization of $C$.
$C{F}_4$, and $Si{F}_4$ are tetrahedral with $s{p}^3$ hybridization..
