The correct sequence of increasing covalent character is represented by

Options

A. LiCl, NaCL, `BeCl_2`
B. `BeCl_2`, NaCl, LiCl
C. NaCl, LiCl, `BeCl_2`
D. `BeCl_2`, LICl, NaCl

Answer

C

Explanation

Smaller the size and greater the charge on cation, more is the covalent character. Ionic sizes of `Li^(+), Na^(+) and Be^(2+)` is in the order `Be^(2+) lt Li^(+) lt Na^(+)`
Therefore correct order of covalent character is `BeCl_2`lt LiCl lt NaCl
