    The correct sequence of increasing covalent character is represented by              [CBSE PMT 2005]

    A)                 \[LiCl<NaCl<BeC{{l}_{2}}\]          

    B)                 \[BeC{{l}_{2}}<NaCl<LiCl\]          

    C)                 \[NaCl<LiCl<BeC{{l}_{2}}\]          

    D)                 \[BeC{{l}_{2}}<LiCl<NaCl\]

    Correct Answer: C

    Solution :

               Order of polarising power \[B{{e}^{++}}>L{{i}^{+}}>N{{a}^{+}}\]                                 Hence order of covalent character \[BeC{{l}_{2}}>LiCl>NaCl\].
