Alkyl halides undergo elimination reactions to produce alkenes by the reacting with strong bases as shown in the following reaction (see image). In general, compounds where the halogen is axial (axial position) are much more reactive than those in which they are in the equatorial position. Taking the above into account: a. Which of the following compounds would give a faster elimination reaction: cis-1-bromo-2-tert-butylcyclohexane or trans-1-bromo-2-tert-butylcyclohexane? Draw the corresponding structures and clearly explain the choice.
As we will learn in Section 13.12, many antioxidants–compounds that prevent unwanted radical oxidation reactions from occurring–are phenols, compounds that contain an OH group bonded directly to a benzene ring. a. Explain why homolysis of the O–H bond in phenol requires considerably less energy than homolysis of the O–H bond in ethanol (362 kJ/mol vs. 438 kJ/mol). b.Why is the C–O bond in phenol shorter than the C–O bond in ethanol?

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

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. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions CH3 CH3 CH3 CH3 H3C H3C :Br: :Br:
