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. WebThese types, often described as non-polar, owing to the presence of vinyl and phenyl groups on the surface, exhibit weakly specific intermolecular interactions with molecules of types B, C and D, but non-specific interactions with all types of adsorbates predominate.
