In the presence of a strong base, 2-chloropropane reacts with hydroxide ions (OH−\text{OH}^-OH−) in an elimination reaction to yield propene, water, and chloride ions:
OH−+H−CH2−CH(Cl)−CH3→H2O+CH2=CH−CH3+Cl− \text{OH}^- + \text{H}-\text{CH}_2-\text{CH}(\text{Cl})-\text{CH}_3 \rightarrow \text{H}_2\text{O} + \text{CH}_2=\text{CH}-\text{CH}_3 + \text{Cl}^- OH−+H−CH2−CH(Cl)−CH3→H2O+CH2=CH−CH3+Cl−
