Solution and Explanation
Step 1: Types of Nucleophilic Substitution 1. SN1 Mechanism (Unimolecular)
- Two-step process involving a carbocation intermediate. 2. SN2 Mechanism (Bimolecular)
- One-step reaction with a transition state.
Step 2: Example - Hydrolysis of Methyl Bromide
\[ CH_3Br + OH^- \rightarrow CH_3OH + Br^- \]
