Electrophilic AdditionThe addition of HCN to a carbonyl compound is an example of electrophilic addition. This is because the HCN molecule acts as an electrophile, or electron-deficient species, and attacks the carbonyl carbon of the carbonyl compound, which is electron-rich. This results in the formation of a new carbon-carbon bond and the addition of the HCN molecule to the carbonyl compound.MechanismThe mechanism of the addition of HCN to a carbonyl compound involves several steps:1. Protonation of the carbonyl compound: The carbonyl compound is protonated by an acid catalyst, which makes the carbonyl carbon more electrophilic and more susceptible to nucleophilic attack.2. Nucleophilic attack by HCN: The HCN molecule attacks the carbonyl carbon, forming a new carbon-carbon bond and creating a tetrahedral intermediate.3. Elimination of water: The tetrahedral intermediate eliminates a water molecule, forming an imine intermediate.4. Addition of H2O: The imine intermediate is then attacked by a water molecule, forming a new tetrahedral intermediate.5. Elimination of HCN: The tetrahedral intermediate eliminates a molecule of HCN, regenerating the carbonyl compound and forming a nitrile.Overall, the addition of HCN to a carbonyl compound involves the addition of an electrophile to an electron-rich carbonyl compound, resulting in the formation of a new carbon-carbon bond and the addition of the HCN molecule.

The addition of HCN to a carbonyl group in the presence of base is a nucleophilic addition reaction where the cyanide ion acts as a nucleophile which attacks at the double bond of carbon and oxygen and forms an addition product.
