WebBiphenyl does not dissolve at all in water. Why is this? Because it is a very non-polar molecule, with only carbon-carbon and carbon-hydrogen bonds. It is able to bond to itself very well through nonpolar van der Waals interactions, but it is not able to form significant attractive interactions with the very polar solvent molecules. WebAug 16, 2024 · Biphenyl, which is formed from a coupling reaction between unreacted bromobenzene and Grignard reagent, is often observed as a major impurity in this reaction. Formation of the side product is favored by high concentrations of bromobenzene and increased reaction temperature.
