Question

Which pair of species having identical shapes?

Options

• BeCl₂, XeF₂, CO₂

• PF₅, IF₅, IF₇

• BF₃, NH₃, PCl₃

• CF₄, SF₄, XeF₄

Answer 1

BeCl₂, XeF₂, CO₂

Explanation:

	Type of hybridization (H)	Geometry
BeCl2	\[\ce{Cl\overset{s}{-} Be \overset{p}{-}Cl}\]	Linear
	H = `1/2` (2 + 2 − 0 + 0) = 2
	H = 2 = sp
XeF2		Linear
	H = `1/2` (8 + 2 − 0 + 0) = 5
	H = 5 = sp3d
CO2	\[\ce{O \overset{s}{=} C \overset{p}{=} O}\]	Linear
	H = `1/2` ()4 + 0 − 0 + 0 = 2
	H = 2 = sp
