Consider the following four xenon compounds: $\mathrm{XeF}_{2}, \mathrm{XeF}_{4}, \mathrm{XeF}_{6}$ and $\mathrm{XeO}_{3}$ The pair of xenon compounds expected to have non-zero dipole moment is
(a)$\mathrm{XeF}_{4}$ and $\mathrm{XeF}_{6}$
(b)$\mathrm{XeF}_{2}$ and $\mathrm{XeF}_{4}$
(c)$\mathrm{XeF}_{2}$ and $\mathrm{XeO}_{3}$
(d)$\mathrm{XeF}_{6}$ and $\mathrm{XeO}_{3}$
Answer
Answer: D ✓ checked by 4AB · confidence high
Explanation
XeF₂ (linear) and XeF₄ (square planar) are centrosymmetric, μ = 0. XeF₆ (distorted octahedron, C₃v) and XeO₃ (trigonal pyramid, C₃v) have non-zero dipole moments.
