Question

2-bromo-2-methylbutane undergoes an e1 elimination reaction in the presence of ethanol. In the next reaction, only one of the possible products is represented. Although the product shown is not the major product of the reaction, notice that there is more than one way it can be produced. What is the major product of the reaction?

Answer 1

The major product of the reaction would be the one that is formed through the E1 mechanism.

Step-by-step explanation:

In the given question, the reaction is an E1 elimination reaction of 2-bromo-2-methylbutane in the presence of ethanol. The major product of the reaction is the one that is formed through the E1 mechanism.

An E1 reaction mechanism occurs when a stable carbocation is formed by elimination of a good leaving group, such as a chloride ion (Cl-). In the E1 mechanism, the only rate-determining step is the dissociation of the leaving group to form a carbocation, followed by the capture of a proton by a base to form the major product.

Therefore, the major product of the reaction would be the one that is formed through the E1 mechanism, which involves the formation of a carbocation and subsequent capture of a proton by a base.
