Explanation:

For Cl², we have two chlorine atoms and they have the same electronegativity. So, the difference in electronegativity between them is zero. Hence it is a non-polar molecule

Water (H²O), like hydrogen fluoride (HF), is a polar covalent molecule. When you look at a diagram of water (see Fig. 3-2), you can see that the two hydrogen atoms are not evenly distributed around the oxygen atom.

Because chlorine is more electronegative than hydrogen, hydrochloric acid HCl forms a polar bond, and is therefore a polar molecule.

Nitrogen molecule is a non polar covalent molecule.
