Question
Based on lattice energy and other considerations which one of the following alkali metal chlorides is expected to have the highest melting point.
Options
A.LiCl
B.NaCl
C.KCl
D.RbCl
Solution
Although lattice energy of LiCl higher than NaCl but LiCl is covalent in nature and NaCl ionic there after, the melting point decreases as we move NaCl because the lattice energy decreases as a size of alkali metal atom increases (lattice energy ∝ to melting point of alkali metal halide)
