The correct answer is:
$\mathrm{LiCl} \lt \mathrm{BeCl}_2 \lt \mathrm{BCl}_3 \lt \mathrm{CCl}_4$
Covalent character increases with decrease in the value of difference in electronegativites of binding atoms. Thus, the correct order is
$\mathrm{LiCl} \lt \mathrm{BeCl}_2 \lt \mathrm{BCl}_2 \lt \mathrm{CCl}_4$
$\mathrm{LiCl} \lt \mathrm{BeCl}_2 \lt \mathrm{BCl}_2 \lt \mathrm{CCl}_4$
