Question

Complete the following reactions: indicate the mechanism (SN1 or SN2). If the reaction does not proceed, indicate so and the reason as to why it would not. 

This image displays three chemical reaction schemes involving different organic compounds and reagents.

1. **First Reaction:**
   - **Reactant:** A cyclic ether compound with a bromo group (Br) attached.
   - **Reagent:** Ethanol (EtOH).
   - **Description:** The structure shows a bromine atom as a leaving group on a cyclohexane ring with an oxygen heteroatom. The reaction likely involves a nucleophilic substitution or elimination in an ethanol solvent.

2. **Second Reaction:**
   - **Reactant:** A chloroalkene featuring a chlorine (Cl) atom and a carbon-carbon double bond.
   - **Reagent:** Water (H₂O).
   - **Description:** This reaction involves an alkene with a chlorine substituent. Water is used as the solvent, suggesting a potential hydrolysis, substitution, or addition reaction with the alkene.

3. **Third Reaction:**
   - **Reactant:** A similar chloroalkene, again with a chlorine (Cl) atom and a carbon-carbon double bond, but possibly in a different position.
   - **Reagent:** Potassium hydroxide (KOH) in water (H₂O).
   - **Description:** The use of KOH, a strong base, indicates that the reaction is likely to be elimination-based, possibly forming an alkene or causing dehydrohalogenation.

These reactions demonstrate different types of organic transformations, including potential substitution and elimination processes, in various solvent conditions.
