Aluminum chloride, AlCl₃, is used in a variety of organic reactions as a Lewis acid. Although it adopts a more complex geometry in the solid state, consider it as a single molecule (i.e., in the gas phase). Given the electron configuration of Al is [Ne]3s²3p¹, how many valence electrons does Al have?

How can I use the Born Haber cycle to establish the lattice energy of CsCl (s)from the following data: ΔHf° [CsCl(s)] = -442.8 kJ/mol; enthalpy of sublimation of Cesium is 78.2 kJ/mol; enthalpy of dissociation of Cl2 (g) = 243 kJ/mol Cl2 ; IE1 for Cs(g) = 375.7 kJ/mol; electron affinity enthalpy-EA1 for Cl(g) = -349kJ/mol.

2. For each pair, choose the compound with the smaller lattice energy, and explain your choice: (a) Cas or Bas (b) NaF or Mgo
