WebHydrogen atoms in polar bonds within any molecule can form bonds with other adjacent molecules. For example, hydrogen bonds hold together two long strands of DNA to give the DNA molecule its characteristic double-stranded structure. Hydrogen bonds are also responsible for some of the three-dimensional structure of proteins. WebThe energies of hydrogen bonds ranges from _____ to _____ kilocalories per mole. The stronger end of that range occurs when there is a greater difference in _____ between the two atoms creating the hydrogen bond. With regards to distance, as the bonds are stronger than van der Waals forces, a hydrogen bond will hold the atoms _____ WebThe forces holding two molecules together in a hydrogen bond are much stronger than those between molecules and hydrocarbons.
