The correct order of increasing covalent character is :

Options

A. `BeCl_2 lt NaCl lt LiCl`
B. `NaCl lt LiCl lt BeCl_2`
C. `BeCl_2 lt LiCl lt NaCl`
D. `LiCl lt NaCl lt BeCl_2`

Answer

B

Explanation

For a given negative ion `(Cl^(-))` the covalent character is directly related to the polarizing power of cation which increases in the order
`Na^(+) lt Li^(+) lt Be^(2+)`
Thus, covalent character increases in the order
`NaCl lt LiCl lt BeCl_2`
