Phenylsuccinic

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.

This … WebA racemic mixture is a 50:50 mixture of two enantiomers. Because they are mirror images, each enantiomer rotates plane-polarized light in an equal but opposite direction and is optically inactive. If the enantiomers are separated, the mixture is said to have been resolved. A common experiment in the laboratory component of introductory organic ...

WebA racemic mixture of phenylsuccinic acid is optically inactive and will have a polarimetry reading of zero. The reaction of phenylsuccinic acid with proline forms diastereomeric bis-salts that are separable based on their solubility in 2-propanol. This allows for the resolution of the enantiomers in the racemic mixture.

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.
