  • question_answer
    Which of the following has been arranged in order of increasing covalent character?

    A) \[KCl<CaC{{l}_{2}}<AlC{{l}_{3}}<SnC{{l}_{4}}\]

    B) \[SnC{{l}_{4}}<AlC{{l}_{3}}<CaC{{l}_{2}}<KCl\]

    C) \[AlC{{l}_{3}}<CaC{{l}_{2}}<KCl<SnC{{l}_{4}}\]

    D) \[CaC{{l}_{2}}<SnC{{l}_{4}}<KCl<AlC{{l}_{3}}\]

    Correct Answer: A

    Solution :

    [a]
    According to Fajan's rule
    Covalent character\[\propto \]charge on cation or anion
    Thus, the correct order is
    \[{{K}^{+}}<C{{a}^{2+}}<A{{l}^{3+}}<S{{n}^{4+}}\]
    \[KCl<CaC{{l}_{2}}<AlC{{l}_{3}}<SnC{{l}_{4}}\]
