Which one of the following pair of compounds contains one that is giant ionic and one that is simple molecule?
Correct answer: A. AI2O3 and Al2CI6
- A. AI2O3 and Al2CI6
- B. P4O10 and PCI3
- C. SiO2 and SiCI4
- D. HF and PbCI4
Explanation
Al2O3 (aluminum oxide) is a giant ionic compound. It consists of a three-dimensional lattice of aluminum ions (Al+3) and oxygen ions (O-2), held together by ionic bonds. It forms a crystal lattice structure.Al2Cl6 (aluminum hexachloride) is a molecular compound and is made up of covalently bonded aluminum and chlorine atoms. It is not a giant ionic compound like Al2O3.

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.
