Which ionic compound would be expected to have the highest lattice energy? A)Rb₂O B)Sr O C)In₂O₃ D)C O₂

Question

Quizplus · Accepted Answer

The lattice energy is directly proportional to the charges of the ions and inversely proportional to the distance between them. Among the given choices, option C has the highest charge on both cation (In3+) and anion (S2-) and also has the shortest distance between them. Hence, it is expected to have the highest lattice energy.
