#C Cl_4# is most covalent in character. Use electronegativity values for each bond or estimate.


The most covalent is just another way of saying the least ionic. To start LiCl and BeCl2 are both ionic compounds, so they are not going to be very covalent in character.

Now we are down to BCl3 and CCl4. Think about the bonding between these two molecules and the electronegativity of their constituent elements.

The difference in electronegativity is less between the C-Cl bond than it is for the B-Cl bond, so C-Cl is the bond which is most covalent in character.
