The correct sequence of increasing covalent character is represented by

Options

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

Answer

C

Explanation

`BeCl_2` has covalent bonds, so maximum covalent characters will be shown by `BeCl_2`.
LiCl and NaCl has ionic bonds. The polarizing power of `Li^(+)` is more than `Na^(+)` due to small size of `Li^(+)`.
