Predict which of the following compounds has the highest melting point.

Question

Quizplus · Accepted Answer

BeF₂ (beryllium fluorosulfate) has the highest melting point because it has the highest charge density among the given options. The high charge density causes stronger electrostatic attractions, which require more energy to overcome and thus result in a higher melting point. NaF, KCl, RbCl, and NaCl have lower charge densities and therefore have lower melting points.
