Question

Question: Predict the major alkene product of the following E1 reaction:

Short answer

Answer

Step-by-step solution

E1 reaction

E1 reaction is a substitution nucleophilic unimolecular reaction. It follows first-order kinetics with respect to the substrate.

In the E1 reaction, the deprotonation of hydrogen occurs leading to the formation of carbocation which forms the alkene.

Formation of product

In the E1 reaction the deprotonation of hydrogen occur lead to the formation of carbocation which forms the alkene by the removal of the halide (Br) as shown as one of the major product:

Formation of Major Product

It also leads to the formation of minor products like:
