Question

Propose a mechanism and predict the products for each reaction. For reactions where more than one product can form, draw all possible products and predict which would be the major product.

The image shows two chemical reactions involving organic molecules, demonstrating substitution and elimination reactions.

1. **Substitution Reaction (S<sub>N</sub>2)**:
   - **Reactant**: The molecule starts with a benzyl group (a benzene ring attached to a CH<sub>2</sub> group), followed by a two-carbon chain ending with a bromine atom (Br).
   - **Reagent**: The reaction takes place with NaO<sup>⊖</sup> and EtOH (ethanol).
   - **Reaction Type**: S<sub>N</sub>2 (bimolecular nucleophilic substitution).

2. **Elimination Reaction (E2)**:
   - **Reactant**: A cyclopropane ring connected to a two-carbon chain with a bromine atom (Br) on the terminal carbon.
   - **Reagent**: The reaction is carried out with KOH in t-BuOH (tert-butanol).
   - **Reaction Type**: E2 (bimolecular elimination).

These reactions show how different conditions (with specific reagents and solvents) can lead to substitution or elimination, showcasing key concepts in organic chemistry.
