0According to Fajans rules the covalent character in an ionic compound is more if the ions are highly charged, cation is small and anion is large. Due to covalent character in the compound, the compound becomes soluble in less polar solvents and also its melting point becomes less. Answer the following:
Which of the following represents the correct order of covalent character?
(a) \( \mathrm{BeCl}_{2}\mathrm{LiCl}\mathrm{NaCl}\mathrm{KCl} \)
(b) \( \mathrm{LiCl}\mathrm{NaCl}\mathrm{KCl}\mathrm{BeCl}_{2} \)
(c) \( \mathrm{LiCl}\mathrm{BeCl}_{2}\mathrm{NaCl}\mathrm{KCl} \)
(d) \( \mathrm{KCl}\mathrm{NaCl}\mathrm{LiCl}\mathrm{BeCl}_{2} \).
