Ethyl Bromide to Pentene
Transformation
Ethyl bromide can be transformed into pentene through
elimination reactions. In these reactions, a single molecule of
ethyl bromide can be converted into one of several possible
alkene products, depending on the reaction conditions.
Elimination reactions can proceed via two possible pathways:
the E1 mechanism and the E2 mechanism. The E1 mechanism is
a two-step process involving the formation of a carbocation
intermediate, while the E2 mechanism is a one-step process
involving the simultaneous departure of a leaving group and the
formation of a pi bond.
In the case of the transformation of ethyl bromide to pentene,
the major product will be the most substituted alkene, in
accordance with Zaitsev's rule. Zaitsev's rule states that, in the
elimination of a single substituent from a molecule, the most
substituted alkene will be the most stable and therefore the
major product.
However, under certain conditions it is possible to form the
Hofmann product, which is the least substituted alkene. This
occurs when the reaction is carried out in the presence of a
