Enantiomers 1 of 6 How can Enantiomers be distinguished? Different effects on plane-polarised light, and said to be optically active. 2 of 6 What is a racemic mixture? A solution in which both enantiomers of a compound are present in equal amounts. 3 of 6 Explain the effects of Brady's Reagent Aldehydes and Keytones both react to form yellow/orange crystalline solids called 2,4 DNP derivatives. Condensation reaction 4 of 6 Explain Fehling's solution If an aldehyde is warmed with Fehlings solution it forms a red/brown precipitate, it has no reaction with keytones. 5 of 6 Explain Tollens' reagent When warmed with an aldehyde a silver metal is formed which coats the test tube as a "silver mirror" but no reaction with a keytone. 6 of 6
