Which of the following pairs of molecules/ions have the same hybridization for their central atom, but different molecular geometries, and consist of one polar and one non-polar species?

Step-by-step solution

Let us analyze each pair based on VSEPR theory: XeF ₄ and XeOF ₄ : In XeF ₄ , Xe has 4 bond pairs and 2 lone pairs ( sp ^3 d ^2 hybridization). Its geometry is square planar, which is highly symmetrical, making it non-polar. In XeOF ₄ , Xe has 5 bond pairs (treating the double bond to O as one superpair for geometry) and 1 lone pair ( sp ^3 d ^2 hybridization). Its geometry is square pyramidal, which is asymmetrical, making it polar. This pair has the same hybridization, different geometries, and one is polar while
