• question_answer 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) $NaCl<LiCl<BeCl$ D) $BeC{{l}_{2}}<LiCl<NaCl$

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