Hydrogen bond

Clean textbook-style molecular schematic of a hydrogen bond shown as a short thin dashed or dotted line, clearly distinct from solid covalent bonds. The interaction is drawn between a hydrogen atom covalently attached to an electronegative donor atom such as oxygen, nitrogen, or fluorine on one polar group or molecule and a nearby electronegative acceptor atom on another group or molecule, with the donor hydrogen oriented directionally toward the acceptor. Typical arrangements include O-H···O, N-H···O, or hydrogen pointing toward O, N, or F, as in neighboring water molecules. It may also be used to indicate an intramolecular hydrogen bond.
