Xe and react at 573 K and 60-70 bar to give compound X. X is partially hydrolysed with one mole of water to Y, and Y with a further mole of water gives Z (a see-saw molecule). Counting each Xe=O as one bond, the total number of Xe-centred bonds in Y and Z together is

  1. A8
  2. B9
  3. C10
  4. D11

Answer: B

X is ; Y is (5 sigma bonds: 4 Xe-F and 1 Xe-O); Z is (4 sigma bonds: 2 Xe-F and 2 Xe-O, see-saw). Total = .
