Question:

Give the two reactions required in order to convert an alcohol into a hydroxynitrile. Include reactants and conditions

Answer:

Convert an alcohol into a ketone by heating it in reflux apparatus with potassium dichromate/K2Cr2O7 and dilute sulfuric acid/H2SO4 (this is an oxidation reaction). Then convert ketone into hydroxynitrile by adding acidified potassium cyanide/KCN (aq) or HCN (g) at 25ºC (this is nucleophilic addition).
