Hydrogen Bonds-Hydrogen bonds are less of chemical bonds and are more of a static attraction. They involve the reaction between a hydrogen atom and an electronegative atom. The strength of a hydrogen bond is less than a tenth of a covalent bond.ydrogen bonds are considerably weak when compared to others, but these weak chemical interactions are very important in the world of biology, dues to the fact that the molecules they form can be easily taken apart and put back together again.
Definition. noun. A type of chemical bond that is formed when the slightly positive hydrogen atom of a polar covalent bond forms an electrostatic link with the more electreonegative atom of a polar covalent bond in the same or another molecule. Supplement. A hydrogen bond is a weak type of chemical bond that is common in organisms. As the name suggests, this type of bond involves a hydrogen atom that is attracted to a strongly electronegative atom such as oxygen, fluorine, or nitrogen of a polar covalent bond in the same or another molecule.
