Water itself consists of covalent bonds. The molecule is angular. the perspective between the two hydrogens is 104.5 levels, which makes it lop-sided. The oxygen is greater constructive by way of its nuclear fee while in comparison with the hydrogens. This makes the molecule quite polar. that's the place the hydrogen comes into effect. the two hydrogens of one molesule have an interest in the quite constructive end of adjacent oxygen ends of the water molecules. This has an effet on the exterior rigidity of the liquid, boiling and freezing factors.
