Pointout Specialized type of Unsaturation

Specialized type of unsaturation: Aromatic compounds are unsaturated cyclic compounds.

  • Aromatic compounds take part in addition reaction with H2, X2, O2 under drastic condition but not with hydro-halogen acids (HX)
  • They are very stable and are not oxidized with KMnO4 solution and not affected by acids.
  • The double bond between two carbons prevents rotation of the atoms about the bond, locking them into specific structural formations.
  • Unsaturated compounds are those in which addition reaction can be obtained. In a chain of carbons, such as a fatty acid, a double or triple bond will cause a kink in the chain.
