Question

Explain the covalent character of lithium chloride using fajans rule

Answer 1

Answer:

Fajan's rule helps to determine the covalent character found in an ionic compound.

According to Fajan's rule, "Smaller is the cation, more is the covalent character.”

Also, "Greater is the polarization, greater is the covalent character".

Therefore, since the size of lithium cation is small and the anion size of chloride is big, the prevalence of covalent character is more as compared to other compounds such as NaCl, KCl, etc.
