The p-Block Elements

Match List I with List II.

List I List II
A. XeO3\mathrm{XeO_3} I. sp3dsp^3d; linear
B. XeF2\mathrm{XeF_2} II. sp3sp^3; pyramidal
C. XeOF4\mathrm{XeOF_4} III. sp3d3sp^3d^3; distorted octahedral
D. XeF6\mathrm{XeF_6} IV. sp3d2sp^3d^2; square pyramidal

Choose the correct answer from the options given below:

  1. A.A-II, B-I, C-IV, D-III✓
  2. B.A-II, B-I, C-III, D-IV
  3. C.A-IV, B-II, C-III, D-I
  4. D.A-IV, B-II, C-I, D-III

Solution

XeO3\mathrm{XeO_3}: sp3sp^3 with one lone pair, pyramidal (II). XeF2\mathrm{XeF_2}: sp3dsp^3d with three lone pairs, linear (I). XeOF4\mathrm{XeOF_4}: sp3d2sp^3d^2 with one lone pair, square pyramidal (IV). XeF6\mathrm{XeF_6}: sp3d3sp^3d^3, distorted octahedral (III).
