Which ionic compound would be expected to have the highest lattice energy? A) NaCl B) Mg Cl₂ C) AlCl₃ D) C Cl₄

Question

Quizplus · Accepted Answer

Lattice energy increases as the charge and size of ions in the compound increase. In choice C, the Al ion has a +3 charge and the Cl ion has a -1 charge, which creates a strong electrostatic attraction. Additionally, the compound has a high coordination number (13), which means there are many ions in close proximity, increasing the strength of the ionic bonds. Therefore, choice C is expected to have the highest lattice energy.
