mechanical energy
mostly covalent bonds as lipids are organic molecules
Hydrogen bonds
disaccharides and polysaccharides
Molecules from the atoms of same element such as hydrogen, oxygen and nitrogen are non-polar molecules and they have covalent bonds in them.

Hydrogen bonds
The molecules of the sugar-phosphate backbone in DNA are joined together by covalent bonds (known as phosphodiester bonds).

Hydrogen Bonds
There are no bonds between hexane molecules. There are intermolecular forces, called London Dispersion Forces which attract other hexane molecules.

Oxygen molecules have covalent bonds.
Hydrogen bond
Water is composed of molecular bonds, but forms hydrogen bonds with other water molecules. Hydrogen bonds are not actual bonds, but they cause an attraction between the water molecules, which is why water is adhesive.
