WebThe halogenoalkane is heated under reflux with a solution of sodium or potassium hydroxide. Heating under reflux means heating with a condenser placed vertically in the flask to prevent loss of volatile substances from the mixture. The solvent is usually a 50/50 mixture of ethanol and water, because everything will dissolve in that. Weban alcohol (R-OH). 7.1 Nucleophilic Substitution Reactions of Haloalkanes Nucleophilic substitution reactions are ionic reactions that break and make chemical bonds by transfers of pairs of electrons. We illustrate this using a general representation of a nucleophilic substitution reaction in which a halogen (X) is replaced by a new group (N).
