1 This attraction forms weak bonds between molecules. 2  When hydrogen is one of the atoms within a molecule that is attracted to the dipole on another molecule, this somewhat stronger dipole-dipole attraction is called a hydrogen bond. The hydrogen bond is the attraction between molecules, not the covalent bond which is formed between hydrogen and an atom from its own molecule. 2  Below are some examples of hydrogen bonding. 3  Click on the image below to see hydrogen bonds represented as dotted lines in this computer model.
