JEE Advanced Chemistry question

Which have distorted geometry based on VSEPR model?

(A)XeF2, XeF4, XeO3
(B)XeOF2, XeO3, XeF2
(C)NH3, SO2, H2O
(D)All of theseCorrect

Answer: (D)

Solution

VSEPR geometry is "distorted" (from the ideal parent shape) whenever lone pairs on the central atom push the bonded atoms out of their textbook positions. In set (a), XeF2 (linear, from a trigonal-bipyramidal parent with 3 lone pairs), XeF4 (square planar, from an octahedral parent with 2 lone pairs) and XeO3
