Which compound is more ionic?
Correct answer: B. CsCl
- A. HF
- B. CsCl
- C. NaCl
- D. H2O
Explanation
CsCl is the most ionic compound out of the four listed. The other three compounds, HF, NaCl, and H2O, are all polar covalent compounds.The ionic character of a bond is determined by the difference in electronegativity between the two atoms that are bonded together. A larger difference in electronegativity means that the bond is more ionic. In CsCl, the difference in electronegativity between cesium and chlorine is 3.22. This is the largest difference in electronegativity out of the four compounds, so CsCl is the most ionic.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
