Question

For BF₃, CO₂, NH₄⁺, SO₃²⁻, BrF₃, SF₆, NO₃⁻, ICl₂⁻, BeCl₂(g), use formal domain-based hybrid labels. Let X count centres using3 p orbitals in that named set, Y using2, Z using1. Find2X+Y−Z. Treat sp³d/sp³d² as including3 p orbitals, not proof of d bonding.

TestHub · Accepted Answer

X=5 from ammonium, sulfite, BrF₃, SF₆, ICl₂⁻. Y=2 from BF₃, nitrate. Z=2 from CO₂, BeCl₂. Thus 10+2−2=10. Lone pairs affect domain labels even when the molecular shape is linear or T-shaped.
