Organic Chemistry
- 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.
