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.
A hydrogen bond is a weak force of attraction that exists between two atoms or ions with opposite charges. For example, the hydrogen-oxygen bonds in water are polar bonds. The hydrogen end of these bonds are slightly positive, and the oxygen ends are slightly negative.ydrogen bond: A chemical bond formed between two atoms or ions with opposite charges. Ionic bond: A chemical bond formed when one atom gains and a second atom loses electrons.
