Study notes
Classify: CH₃CH₂Br + OH⁻ → CH₃CH₂OH + Br⁻. Step 1: Count atoms: Br leaves, OH enters — same carbon skeleton. Step 2: One group replaced by another → substitution. Step 3: Specifically nucleophilic substitution (OH⁻ is the nucleophile). Step 4: Mechanism SN1 or SN2 depending on substrate. Substitution identified!
