WebIn this experiment, racemic (R + S)-phenylsuccinic acid is separated (resolved) into optically active enantiomers in a sequence of two steps. First, we exploit its chemical nature (it is an acid) by treating it with an optically active biologically produced base, L-proline. This is an ordinary acid - base reaction that produces a salt.

WebThe (+) isomer and the (-) isomer of phenylsuccinic acid have the same _____ and _____ properties. Solubilities However, if the acid is combined with an optically active base, such as (-)-proline, the diastereomers which form have different ______ in isopropyl alcohol. Less WebTwo protons are transferred from the phenylsuccinic acid to the proline. One proline has a position available for one extra proton, so the two protons end up on two different prolines. Because protons have +1 charge, each proline is cationic. The phenylsuccinic acid gave up two positives, so it is a dianion.
