The correct sequence of increasing covalent character is represented by

Options

(a) LiCl (b) BeCl₂ (c) NaCl (d) BeCl₂

Correct Answer:

NaCl Explanation:

As difference of electronegativity increases % ionic character increases and covalentcharacter decreases i.e. negativity differences decreases covalent character increases.
Further greater the charge on the cation more will be its covalent character.Be has maximum (+2) charge.
