Millon’s reagent is concentrated HNO3, in which mercury is dissolved. As a result of the reaction a red precipitate or a red solution is considered as positive test. A yellow precipitate of HgO is NOT a positive reaction but usually indicates that the solution is too alkaline. Apply this test to tyrosine, phenylalanine, glycine and β-naphtol. (A) Predict which molecule/s will yield a positive result (B) Predict which molecule/s will yield a negative result
