Question
### SN1/E1 Reaction: Major E1 Product Identification **Question:** What is the major E1 product formed in the given \( S_N1 / E1 \) reaction? **Options:** - **A:** 1. - **B:** 2. - **C:** 3. - **D:** 4. **Reaction Details:** The reaction starts with a molecule containing a bromine (Br) substituent on a carbon chain. Under the influence of heat and methanol (\( \text{CH}_3\text{OH} \)), the major E1 product needs to be identified. **Diagrams:** Below the question, there is a depiction of the chemical reaction: 1. **Reactant:** The starting molecule with bromine. 2. **Reaction Conditions:** Heat and methanol (\( \text{CH}_3\text{OH} \)). 3. **Expected Products:** Four possible products are illustrated with respective double bond positions. **Potential Major E1 Products:** 1. **Product 1:** A carbon chain with a double bond between the first and second carbon atoms. 2. **Product 2:** A carbon chain with a double bond between the second and third carbon atoms. 3. **Product 3:** A carbon chain with a double bond between the first and second carbon atoms, but with different connectivity. 4. **Product 4:** A carbon chain with a double bond between the third and fourth carbon atoms. Students should analyze the elimination reaction mechanism (E1) to determine which product is formed as the major product. Factors typically considered include the formation of the most stable (usually more substituted) alkene and the rearrangement possibilities during the transition state of the carbocation intermediate.
