Consider the pair of reactions. Draw the organic products, then predict the type of substitution mechanism and compare the expected rates.

 

**Organic Reactions: Nucleophilic Substitution** **Consider the pair of reactions. Draw the organic products, then predict the type of substitution mechanism and compare the expected rates.** **Reaction 1:** - **Reactants:** - 1-chloropropane (\( \text{Cl} \)) and methoxide ion (\( \text{OCH}_3^- \)) - Methoxide ion concentration: \( 0.1 \, \text{M} \) - **Conditions:** - Solvent: DMA (Dimethylacetamide) - **Process:** - The methoxide ion attacks the carbon bonded to the chloride ion, forming product 1. **Reaction 2:** - **Reactants:** - 2-chloropropane (\( \text{Cl} \)) and methoxide ion (\( \text{OCH}_3^- \)) - Methoxide ion concentration: \( 0.2 \, \text{M} \) - **Conditions:** - Solvent: DMA (Dimethylacetamide) - **Process:** - The methoxide ion attacks the carbon bonded to the chloride ion, forming product 2. **Mechanism and Rate Comparison:** - Analyze the structure of reactants and predict whether each reaction proceeds via \( \text{S}_N1 \) (unimolecular nucleophilic substitution) or \( \text{S}_N2 \) (bimolecular nucleophilic substitution) mechanisms. - Consider the concentration of methoxide ion and the nature of the carbon-chlorine bond in both reactions to predict and compare reaction rates. These exercises will help you understand the mechanistic pathways and influencing factors in nucleophilic substitution reactions.
