The correct sequence of increasing covalent character is represented by
Options
- AB e C l 2 < N a C l < L i C l
- BB e C l 2 < L i C l < N a C l
- CN a C l < L i C l < B e C l 2
- DL i C l < N a C l < B e C l 2
Correct answer
C. N a C l < L i C l < B e C l 2
Step-by-step solution
The covalent character of ionic compound depends on polarising power of cation. Order of polarising power of cation is B e + + > L i + > N a + , Hence order of covalent character B e C l 2 > L i C l > N a C l .
