10. Terpene is a class of naturally occurring molecules, found in many essential oils from plants, that share thesame alkene features. All terpenes have a similar 5 carbon unit that includes an alkene thought to bebiologically synthesized from the molecule isoprene.All terpenes are biosynthesized from molecules with the good leaving group: pyrophosphate (OPP). Loss ofthis OPP leads to the formation of a resonance stabilized carbocation. The new carbocation can undergo anucleophilic attack from a T-bond as seen in acid-catalyzed hydration and hydrohalogenation, forming a newcarbocation. This new carbocation can undergo an E1 reaction to form a new alkene.Add the curved arrows of the following reaction.hoppCOPPD5R-carvone(spearmint oil)-Q Search406&COPP1COPPCOPP

CH3 CH3 Br- Br2 .CH3 CH2Cl2 CH3 H3C H3C Br Electrophilic addition of bromine, Brɔ, to alkenes yields a 1,2-dibromoalkane. The reaction proceeds through a cyclic intermediate known as a bromonium ion. The reaction occurs in an anhydrous solvent such as CH,Cl,. In the second step of the reaction, bromide is the nucleophile and attacks at one of the carbons of the bromonium ion to yield the product. Due to steric clashes, the bromide ion always attacks the carbon from the opposite face of the bromonium ion so that a product with anti stereochemistry is formed.
