Question

For each of the following elimination/dehydration reactions, predict the products, including the major product where indicated. Also indicate if the reaction would proceed through E1 or E2. 

**3. Reaction Fill-ins:** For each of these elimination/dehydration reactions, predict the products, including the major product where indicated. Also, indicate if the reaction would proceed through E1 or E2. 1. **Reaction 1:** - **Reactant:** Benzyl alcohol (PhCH2OH) - **Reagent/Condition:** H2SO4 and heat (Δ) - **Products:** [To be predicted], determine if the reaction proceeds through E1 or E2. 2. **Reaction 2:** - **Reactant:** Cyclohexanol with a methyl group (CH3,OH) - **Reagent/Condition:** H2SO4 and heat (Δ) - **Products:** Multiple products need to be predicted. Mark the major product and determine if the reaction is E1 or E2. 3. **Reaction 3:** - **Reactant:** Tertiary alcohol with methyl groups (CH3)2C(CH3)OH - **Reagent/Condition:** H2SO4 and heat (Δ) - **Products:** Multiple products need to be predicted. Mark the major product and determine if the reaction is E1 or E2. **Guidance:** - **E1 Reaction:** Typically involves the formation of a carbocation intermediate and is common with tertiary alcohols. The major product is usually the more substituted alkene (Zaitsev's rule). - **E2 Reaction:** Proceeds via a one-step mechanism where the base removes a hydrogen, and the leaving group departs simultaneously. Less common with strong acids like H2SO4 used in these conditions.
