To understand why some alkyl halides undergo substitution reactions while others undergo elimination reactions when treated with bases, we need to consider the structural features of the alkyl halides and the nature of the bases used. Here’s a step-by-step explanation: ### Step 1: Understand the Types of Reactions Alkyl halides can undergo two main types of reactions when treated with bases: - **Substitution Reactions (SN1/SN2)**: In these reactions, a nucleophile replaces the halogen atom in the alkyl halide. - **Elimination Reactions (E1/E2)**: In these reactions, the alkyl halide loses a halogen and a hydrogen atom, resulting in the formation of a double bond. ### Step 2: Identify the Role of the Base ...
