Describe Solubility of Alkanes, Alkenes and Alkynes

Any molecule’s solubility in things depends a lot on whether it is a polar molecule or a non-polar molecule. So, polar molecules are soluble in other polar molecules and non-polar molecules are soluble in other non-polar molecules.

The solubility of Alkanes, Alkenes, and Alkynes:

Solubility of Alkanes

  • Alkanes are insoluble in water because they are non-polar.
  • They are soluble in various organic solvents. Example: Benzene. ether etc.
  • The solubility of alkanes show a gradual decrease with increase in the molecular mass (chain lengths)

Solubility of Alkene

  • Alkenes are Insoluble in water because they are also non-polar and covalent compounds.
  • Alkenes are Soluble in a various organic solvent. Example: Benzene, ether, alcohol, etc.

Alkanes and alkenes are non-polar molecules. Water, on the other hand, is a polar molecule. So, alkanes and alkenes are not soluble in water.

The solubility of Alkynes

Alkynes are generally nonpolar molecules with little solubility in polar solvents, such as water.

  • Insoluble in water.
  • Soluble in various organic solvent.
  • They are insoluble in water but readily dissolve in organic solvents such as ether, carbon tetrachloride, and benzene.
