An understanding of bond dipoles and the various types of noncovalent intermolecular forces allows us to explain, on a molecular level, many observable physical properties of organic compounds. In this section, we will concentrate on solubility, melting point ... WebThe compound with the larger Rf is less polar because it interacts less strongly with the polar adsorbent on the TLC plate (silica) How do we know the similarity of two substance? If two substance have the same Rf value, they are likely but not necessarily the same compound. If they have different Rf, they are definitely different compounds.
