Which of the following compounds has the lowest lattice energy? A) Ca(OH)₂ B) KBr C) InAs D) ZnS E) SrSe

Question

Quizplus · Accepted Answer

The lattice energy of an ionic compound depends on the charge of the ions and the distance between them. The smaller the ions and the higher their charge, the greater the lattice energy. Option B, KBr, has the lowest lattice energy because both K+ and Br- are relatively large ions with lower charges compared to the other options. The other options have smaller ions or higher charges or both, leading to higher lattice energies.
