Mixing SbCl 3 and GaCl 3 in a 1 : 1 molar ratio (using liquid sulfur dioxide as a solvent) gives a solid ionic compound of empirical formula GaSbCl 6 . A controversy arises over whether this compound is ( SbCl 2 + ) ( GaCl 4 − ) or ( GaCl 2 + ) ( SbCl 4 − ) . (a) Predict the molecular structures of the two anions. (b) It is learned that the cation in the compound has a bent structure. Based on this fact, which formulation is more likely to be correct?

Aluminum oxide (Al₂ O₃) is a widely used industrial abrasive(emery, corundum), for which the specific application depends onthe hardness of the crystal. What does this hardness imply about the magnitude of the lattice energy? Would you have predictedfrom the chemical formula that Al₂ O₃ is hard? Explain.
The precious gem ruby aluminum oxide, Al2O3 containing traces of Cr3+. The compound Al2Se3 is used in the fabrication of some semiconductor devices. Which of the two has a larger lattice energy?
