MCQ
The correct sequence of increasing covalent character is represented by
- A$LiCl < NaCl < BeC{l_2}$
- B$BeC{l_2} < NaCl < LiCl$
- ✓$NaCl < LiCl < BeC{l_2}$
- D$BeC{l_2} < LiCl < NaCl$
✓
Answer
Correct option: C.
$NaCl < LiCl < BeC{l_2}$
(c) Order of polarising power $B{e^{ + + }} > L{i^ + } > N{a^ + }$ Hence order of covalent character $BeC{l_2} > LiCl > NaCl$.
