SUMMARY
Halogenoalkanes react through nucleophilic substitution when refluxed with HCN in an ethanolic KCN solution. The cyanide ion (CN-) acts as the nucleophile, while HCN itself does not participate as a nucleophile. Without the presence of ethanolic KCN, pure HCN fails to generate the necessary cyanide ions, resulting in no reaction with halogenoalkanes. This confirms the critical role of KCN in facilitating the nucleophilic substitution process.
