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

A

RbCl

B

RCl

C

NaCl

D

LiCl

Text Solution

Verified by Experts

The correct Answer is:
C

As we go down in the group, ionic character increases hence, melting point of halides should increase but NaCl has the highest melting point `(800^(@)C)` due to its high lattice energy.
