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.
- How could the following changes in reaction conditions affect the rate of the reaction
when isopropanol (IPA) reacts with 2-bromo-2-methylpentane?
The concentration of the IPA is halved by adding petroleum ether as the solvent.
b. The concentration of the bromoalkene is quadrupled.
