Final answer:
The question involves verifying the correct elimination product in an E1 reaction in organic chemistry. The E1 mechanism is unimolecular and competes with the SN1 reaction due to their common carbocation intermediate.
Step-by-step explanation:
The student's question pertains to identifying whether a given product is the correct one for an elimination reaction, likely in the context of organic chemistry. Specifically, an E1 reaction is indicated, where a leaving group and a proton adjacent to the leaving group are removed, forming a double bond. This mechanism is unimolecular, meaning that the rate-determining step involves a single molecule. An E1 elimination competes with SN1, a nucleophilic substitution reaction, because they share the same first step which involves the formation of a carbocation.
