Q12 / 225 · JEE Main 2002 · Chemistry

In $\mathrm{XeF}_2, \mathrm{XeF}_4, \mathrm{XeF}_6$ the numebr of lone pairs of $\mathrm{Xe}$ are respectively

  • A
    2, 3, 1
  • B
    1, 2, 3
  • C
    4, 1, 2
  • Correct answer
    D
    3, 2, 1

Solution

$\begin{array}{lll}\mathrm{XeF}_2 & \mathrm{sp}^3 \mathrm{~d} & 3 \text { lone pairs } \\ \mathrm{XeF}_4 & \mathrm{sp}^3 \mathrm{~d}^2 & 2 \text { lone pairs } \\ \mathrm{XeF}_6 & \mathrm{sp}^3 \mathrm{~d}^3 & \text { 1 lone pair }\end{array}$

Hence, the correct answer is option: 'D'.
