Question

What is the hybridization and geometry of the given species ? The species are $ XeF_2 $ and $ ICl_2^- $ .

• A. $ sp^3\,d $ and trigonal bipyramidal
• B. $ sp^3\,d^2 $ and square planar
• C. $ sp^3d $ and linear
• D. $ sp^3 $ and irregular tetrahedron

Answer 1

Answer: (C)

Number of hybrid orbitals (X)
$=\frac{1}{2}[V.E. + M.A. -c+a]$
For $XeF_{2}: (X) =\frac{1}{2}(8+2)=5$ i.e., $sp^{3}d$ hybridisation
For $ICl_{2}:(X)=\frac{1}{2}(7+2+1)=5$ i.e., $sp^{3}d$ hybridisation
