Hydrogen bonding is responsible for the fact that ice is less dense than liquid water. In ice, water molecules form a crystalline lattice held together by hydrogen bonds, which leave empty spaces or pockets between the molecules. In liquid water, the hydrogen bonds are constantly breaking and reforming, allowing the molecules to pack more tightly and resulting in a higher density.
