WebHydrogen bonds and London dispersion forces. Covalent and ionic bonds are both typically considered strong bonds. However, other kinds of more temporary bonds can also form between atoms or molecules. Two types of weak bonds often seen in biology are … Ionic bonds and Coulomb's law (Opens a modal) Practice. Intramolecular force … WebJun 9, 2024 · A bond in which the electronegativity difference between the atoms is between 0.4 and 1.7 is called a polar covalent bond. A polar covalent bondis a covalent bond in which the atoms have an unequal attraction for electrons, so the sharing is unequal.
