Aromatic Compounds

Aromatic organic compound or aromatic system is an important class of hydrocarbons under the branch of organic chemistry. Aromatic compounds are also called arenas. The definition of aromatic organic compounds can be stated as a class of organic compounds with a planar cyclic ring of atoms bonded through alternated single and double bonds. Due to these alternating bonds, a peculiar feature termed as ‘resonance’, that is, delocalization of pi electrons or the electrons is shared within the atoms of the ring which are present in the aromatic compounds. The word ‘aromatic’ includes a Greek word ‘aroma’ which means smell, indicating that they were named as such due to the sweet odor they produce. Many well-known flavors such as vanilla, cinnamon, and few scents from flowers are extracted from aromatic compounds. Benzene with chemical formula C6H6 is a very common aromatic compound that contains six atoms of carbon held in the cyclic ring of alternate double bonds. It is also to be noted that not all aromatic compounds contain benzene ring. This can be explained by Huckel’s rule.

10. Terpene is a class of naturally occurring molecules, found in many essential oils from plants, that share the same alkene features. All terpenes have a similar 5 carbon unit that includes an alkene thought to be biologically synthesized from the molecule isoprene. All terpenes are biosynthesized from molecules with the good leaving group: pyrophosphate (OPP). Loss of this OPP leads to the formation of a resonance stabilized carbocation. The new carbocation can undergo a nucleophilic attack from a T-bond as seen in acid-catalyzed hydration and hydrohalogenation, forming a new carbocation. This new carbocation can undergo an E1 reaction to form a new alkene. Add the curved arrows of the following reaction. hopp COPP D 5 R-carvone (spearmint oil) - Q Search 40 6 & COPP 1 COPP COPP
