Consider these statements. (i) $XeO X_{3} F X_{2}$ is trigonal bipyramidal with the three O atoms in the equatorial plane. (ii) $XeF X_{3} X^{+}$ is T-shaped with both lone pairs equatorial. (iii) In $XeO X_{2} F X_{2}$ the lone pair of Xe is axial. (iv) All six atoms of $XeF X_{5} X^{-}$ lie in one plane. (v) $XeO X_{6} X^{4 -}$ is octahedral with $s p^{3} d^{2}$ Xe. The number of correct statements is

Answer: C

(i) true:

XeO X_{3} F X_{2}

has no lone pair, and the three O atoms (multiple-bond character) lie in the equatorial plane with two axial F. (ii) true. (iii) false: the lone pair of

XeO X_{2} F X_{2}

is equatorial (see-saw). (iv) true: pentagonal planar. (v) true. So 4 are correct.
