Comment on solubility

Solubility of Undecane

Undecane, with the chemical formula C11H24, is a straight-chain alkane consisting of eleven carbon atoms. Speaking of solubility, it is important to note the following:

  • Hydrophobic Nature: Undecane is a non-polar molecule, which makes it largely insoluble in water. Instead, it dissolves well in non-polar solvents.
  • Solvent Compatibility: It is soluble in various organic solvents, including:
    • Hexane
    • Heptane
    • Octane
    • Toluene
  • Temperature Dependence: Like most hydrocarbons, solubility in organic solvents may increase with temperature due to enhanced molecular interactions.

As a reminder, the solubility characteristic of undecane highlights the principle that “like dissolves like.” This means that non-polar solvents will effectively dissolve non-polar solutes such as undecane, while polar substances like water will not.


Understanding these solubility patterns is crucial for applications in various fields, including chemistry and environmental science.
