addition to aldehydes and ketones - chemguide

The reaction isn't normally done using hydrogen cyanide itself, because this is an extremely poisonous gas. Instead, the aldehyde or ketone is mixed with a solution of sodium or potassium cyanide in water to which a little sulphuric acid has been added. The pH of the solution is adjusted to about 4 - 5, because this gives the fastest reaction.

Synthesis of Phenyl-2-Propanone (P2P) - [www.rhodium.ws

Phenyl-2-Propanone from Acetone Enolate. If acetone is reacted with a strong base, which is able to deprotonate one of the relatively acidic alpha protons of the ketone, acetone enolate is formed in quantitative yield. Such strong bases include sodium amide, lithium diisopropylamide and several alkoxides, for example potassium tert-butoxide.

Oxidation-Reduction Equations - Purdue University

The Half-Reaction Method of Balancing Redox Equations . A powerful technique for balancing oxidation-reduction equations involves dividing these reactions into separate oxidation and reduction half-reactions. We then balance the half-reactions, one at a time, and combine them so that electrons are neither created nor destroyed in the reaction.

19.6: Nucleophilic Addition of HCN: Cyanohydrin Formation

Example. Hydrogen cyanide (HCN) is hazardous to handle because it is highly toxic. Therefore in many syntheses of cyanohydrins, HCN is created in situ by adding a strong acid to a mixture of sodium cyanide and the carbonyl compound, so that hydrogen cyanide is generated in situ.The amount of acid added should be insufficient to consume all the cyanide ion, therefore sufficiently alkaline
