Hydrogen bond

Clean textbook-style molecular schematic of a hydrogen bond shown as a short, thin dashed or dotted line spanning a small gap between molecular groups. The connector is straight, delicate, evenly spaced, and rendered in light gray, pale blue, or blue-gray so it appears weaker and less solid than covalent bonds. It links a partially positive hydrogen atom on one donor group to a nearby electronegative acceptor atom such as oxygen or nitrogen on another molecule or polar group. Typical contexts include adjacent bent water molecules, paired DNA bases, or other polar molecular groups, with the hydrogen bond clearly distinguished from solid covalent bonds in a minimal chemistry-diagram style.
