WebJan 30, 2024 · Recrystallization, also known as fractional crystallization, is a procedure for purifying an impure compound in a solvent. The method of purification is based on the principle that the solubility of most solids increases with increased temperature. WebBiphenyl does not dissolve at all in water. Why is this? It is a very non-polar molecule, with only carbon-carbon and carbon-hydrogen bonds. It has some intermolecular forces bonding it to itself through nonpolar London dispersion forces, but it has no significant attractive interactions with very polar solvent molecules like water.
