**Analysis of Organic Reactions and Mechanisms**This exercise involves analyzing different organic reactants and the conditions under which they react, predicting the major organic product structures, and identifying the predominant mechanisms: $ \text{S}_\text{N}1 $, $ \text{S}_\text{N}2 $, E1, or E2.1. **Reaction 1:** - **Reactant:** 1-bromobutane ($ \text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{Br} $) - **Reagent:** Potassium tert-butoxide ($ \text{K} \, \text{OC}(\text{CH}_3)_3 $) - **Solvent and Temperature:** $ (\text{CH}_3)_3\text{COH} $, $ 82^\circ \text{C} $ - **Likely Mechanism:** E2 (due to strong base and heat) - **Predicted Major Product:** Butene2. **Reaction 2:** - **Reactant:** 1-bromobutane ($ \text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{Br} $) - **Reagent:** Sodium methoxide ($ \text{Na} \, \text{OCH}_3 $) - **Solvent and Temperature:** Methanol ($ \text{CH}_3\text{OH} $), $ 0^\circ \text{C} $ - **Likely Mechanism:** $ \text{S}_\text{N}2 $ (due to strong nucleophile, low temperature) - **Predicted Major Product:** Butyl methyl ether3. **Reaction 3:** - **Reactant:** 1-bromo-2-methylpropane - **Reagent:** Sodium methanethiolate ($ \text{Na} \, \text{SCH}_2\text{CH}_3 $) - **Solvent and Temperature:** DMF, $ 0^\circ \text{C} $ - **Likely Mechanism:** $ \text{S}_\text{N}2 $ (due to strong nucleophile,

If substance is primary/secondary means streric repulsion free and solvent is aprotic like DMF then SN2 reaction occurs. If substance is tertiary then SN1 reaction occurs as it gives stable carbocation formation.If substance is tertiary and base is strong with good leaving group then E2 reaction occurs. 1. In presence of strong base it undergo E2 elimination reaction. 2. In presence of strong nucleophile it undergo SN2 substitution reaction.3. In presence of DMF it undergo SN2 substitution reaction.4. Here, also SN2 reaction gives nitro methane.
