How KCN reacts with alcohal?

Potassium cyanide (KCN) can react with alcohols through a nucleophilic substitution mechanism. In this reaction, the cyanide ion (CN⁻) acts as a nucleophile, attacking the electrophilic carbon atom of the alcohol's hydroxyl group (–OH), leading to the formation of alkoxy cyanides. This process typically requires acidic or basic conditions to facilitate the conversion of the alcohol to a better leaving group, often resulting in the formation of a cyanohydrin. However, such reactions should be handled with caution due to the toxicity of KCN.
