The compounds BrCl and BrI melt at –66 °C and 42 °C, respectively.
What is the best explanation for this difference in melting points?
A. The Br−I covalent bond is stronger than the Br−Cl covalent bond.
B. Chlorine is more reactive than iodine so chlorine breaks away from bromine more readily than iodine.
C. The forces between BrI molecules are stronger than the forces between BrCl molecules.
D. Iodide ions are larger than chloride ions so bromide ions form stronger ionic bonds with iodide ions than with chloride ions.
E. Iodine atoms are larger than chlorine atoms so the BrI giant covalent lattice is more difficult to break up than the BrCl giant covalent lattice.
