1. hydrogen bond - Noun
2. hydrogen bond - Verb
a chemical bond consisting of a hydrogen atom between two electronegative atoms (e.g., oxygen or nitrogen) with one side be a covalent bond and the other being an ionic bond
Source: WordNetAs a result, there is an electrostatic attraction between the oxygen atom of one water molecule and the hydrogen of another (Fig. 2-lb), called a hydrogen bond. Albert L. Lehninger
Advanced theory of the hydrogen bond In 1999, Isaacs et al. citation showed from interpretations of the anisotropies in the Compton profile of ordinary ice that the hydrogen bond is partly covalent. Source: Internet
Appropriate geometrical correspondence of hydrogen bond donors and acceptors allows only the "right" pairs to form stably. Source: Internet
As one moves from primary to secondary to tertiary alcohols with the same backbone, the hydrogen bond strength, the boiling point, and the acidity typically decrease. Source: Internet
Depending on geometry and environment, the hydrogen bond free energy content is between 1 and 5 kcal/mole. Source: Internet
Guanine has the C-6 carbonyl group that acts as the hydrogen bond acceptor, while a group at N-1 and the amino group at C-2 act as the hydrogen bond donors. Source: Internet
