Problem

If the central atom is in the third period or below in the periodic table, then a lone pair may occupy a stereochemically inactive

s

orbital and bonding may occur through almost pure

p

orbitals, with bond angles nearly

90^\circ

, when the substituent electronegativity is

\leq2.5

. The hybridisation of the central atom Xe in

\mathrm{XeO}_4

\mathrm{XeO}_2\mathrm{F}_2

, and

\mathrm{XeOF}_4

, respectively, is (1)

sp^3,\ sp^3d^2,\ sp^3d^2

(2)

sp^3d,\ sp^3d,\ sp^3d^2

(3)

sp^3,\ sp^3d^2,\ sp^3d

(4)

sp^3,\ sp^3d,\ sp^3d^2
