JEE Advanced · 2012 · 08 Apr 2012 · Paper 2 · Chemical Bonding and Molecular Structure

The shape of

XeO_{2} F_{2}

molecule is

(A)trigonal bipyramidal
(B)square planar
(C)tetrahedral
(D)see-saw✓ Correct

Answer: (D)

Solution

XeO₂F₂ has 5 electron pairs around Xe (2 double bonds with O, 2 single bonds with F, and 1 lone pair). The hybridization is sp³d with a trigonal bipyramidal electron geometry. With one lone pair in the equatorial position, the molecular shape is see-saw. The answer is (D).
