The correct sequence of increasing covalent character is represented by

Answer»

`LiClltNaClltBeCl_(2)`
`BeCl_(2)ltLiClltNaCl`
`NaClltLiClltBeCl_(2)`
`BeCl_(2)ltNaClltLiCl`

SOLUTION :As DIFFERENCE in electronegativity increases, the % ionic character increase and COVALENT character decreases. Electronegativities of LI, Na and Be are 1.0, 0.9, 1.5 and of Cl is 3.0.
