Use the information from the passage to answer the following questions Supramolecular chemistry involves the study of noncovalent interactions within and between molecules. For years chemists have focused on studying molecules and compounds that are held together by covalent bonds and ionic bonds, and how these bonds are formed and broken during chemical reactions. But now researchers in supramolecular chemistry are studying the weaker electrostatic attractions and reversible noncovalent interactions, such as hydrogen bonding. b) How are ionic and covalent bonds different from hydrogen bonds
