How to produce hydroxynitriles

Draw the mechanism - page 422

React aldehydes or ketones with potassium cyanide followed by a dilute acid.

New cards

How does the nucleophilic attack of cyanide ions (KCN) on aldehydes or ketones lead to a racemic mixture of hydroxynitriles

  • Double bonds such as CC AND CO are planar.

  • So when nucleophiles attack the double bonds they can attack from above or below of equal chance.

  • equal mixture of both enantiomers

enantiomer

pair of molecules that are mirror images of each other.
