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

LiCl

NaCl

KCl

RbCl

Text Solution

Verified by Experts

The correct Answer is:

Although lattice energy of LiCl is higher than that
of NaCl but LiCl is covalent in nature and NaCl is
ionic. After NaCl , lattice energy decreases as the
size of the alkali metal ion increases . As melting
point depends upon lattice energy and ionic/
covalent nature of the compound , NaCl has the
highest melting point .
