Question #08146

Answer 1

(a) `"CaBr"_2`

Explanation:

In general, the stronger the intermolecular forces between molecules, the higher their melting (and boiling) point. Since ionic bonds (ion-ion intermolecular force) are much stronger than the other forces, we'd expect `"CaBr"_2` to have the highest melting point, since it's the only compound with ion-ion forces (ionic bonding).
