A) LiCl
B) NaCl
C) KCl
D) RbCl
Correct Answer: B
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 \[\propto \] melting point of alkali metal halide)You need to login to perform this action.
