Comment on solubility

Solubility of Biphenyl

Biphenyl, with the chemical formula C12H10, exhibits interesting solubility characteristics. Generally, it is considered to be a non-polar organic compound, which significantly influences its solubility behavior:

  • In Water: Biphenyl is sparingly soluble in water, primarily due to its non-polar nature. As a rule of thumb, "like dissolves like," meaning polar solvents like water don't interact effectively with non-polar substances.
  • In Organic Solvents: Conversely, biphenyl demonstrates good solubility in a variety of organic solvents, including:
    • Benzene
    • Toluene
    • Hexane
  • Temperature Dependency: The solubility of biphenyl in organic solvents can vary with temperature, generally increasing as temperature rises, which is a common trait among organic compounds.

In summary, biphenyl's solubility profile underscores the importance of polarity in solvent interactions. As noted, it is likely to dissolve readily in non-polar solvents while exhibiting minimal solubility in polar solvents like water.
