Each comprehension given below is followed by some multiple choice questions. Each question has one correct option. Choose the correct option.
Comprehension 9 According to Fajan rules,
the percentage of covalent character in an
ionic compound increases if the cation is
highly charged or the cation is small and the
anion is large or the cation has pseudo inert
gas configuration. As a result of increased
covalent character, the melting point
decreases and solubility in less polar solvent
increases.
The correct order of increasing ionic character is
(A) \( \mathrm{BeCl}_{2}\mathrm{MgCl}_{2}\mathrm{CaCl}_{2}\mathrm{BaCl}_{2} \)
(B) \( \mathrm{BeCl}_{2}\mathrm{MgCl}_{2}\mathrm{BaCl}_{2}\mathrm{CaCl}_{2} \)
(C) \( \mathrm{BeCl}_{2}\mathrm{BaCl}_{2}\mathrm{MgCl}_{2}\mathrm{CaCl}_{2} \)
(D) \( \mathrm{BaCl}_{2}\mathrm{CaCl}_{2}\mathrm{MgCl}_{2}\mathrm{BeCl}_{2} \)
