Question

For SF₆, SeF₄, BrF₃, ICl₂⁻, NO₃⁻, SO₃²⁻, CO₂ and BF₄⁻, use ideal models. Let x count species with inequivalent ligand positions, y those assigned formal sp³d or sp³d² labels, and z fully planar species. Find (2x+y)/z. Do not treat formal d labels as proof of d participation or resonance contributors as inequivalent positions.

Answer:

2

Solution:

x=2 from SeF₄, BrF₃; y=4 from SF₆, SeF₄, BrF₃, ICl₂⁻; z=4 from BrF₃, ICl₂⁻, nitrate, CO₂. Sulfite is pyramidal and tetrafluoroborate tetrahedral. Thus (4+4)/4=2.
