Give the two reactions required in order to convert an alcohol into a hydroxynitrile. Include reactants and conditions. (6 marks)

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 25^oC (this is nucleophilic addition)
