Hydrogen Bond: An attraction between a slightly positive hydrogen on one molecule and a slightly negative atom on another molecule.
A hydrogen bond is the electrostatic attraction between two polar groups that occurs when a hydrogen (H) atom covalently bound to a highly electronegative atom such as nitrogen (N) or oxygen (O) experiences the electrostatic field of another highly electronegative atom nearby.
