In which pair do both compounds exhibit predominantly ionic bonding? A) KF and O₃ B) PBr₅ and HF C) NaF and H₂S D) NaCl and SrO E) Na₂SO₃ and BCl₃

Question

Quizplus · Accepted Answer

NaCl and SrO both contain a metal cation (Na+, Sr2+) and a non-metal anion (Cl-, O2-) and have a large electronegativity difference, indicating predominantly ionic bonding. The other pairs may contain some ionic character, but also have covalent character due to smaller electronegativity differences or the presence of multiple non-metal atoms.
