Question

Based on lattice energy and other considerations which one of the following alkali
metal chlorides is expected to have the highest melting point :

Accepted Answer

Option B. … has partly covalent character. Other halides are ionic in nature. Lattice energy decreases with increases of ionic radius of cation, anion being the same. Larger is the lattice energy, the higher will be … … hence … will have highest lattice energy.
