Enantiomers have the same physical properties and cannot be separated using typical laboratory methods. in general, separation can be achieved by converting a racemic mixture to two different diastereomers, which can then be separated. given the racemic amine and chiral resolving agent below, identify the two diastereomers formed. use the following order x, y, z, where x refers to the configuration of the amine, while y and z refer to the configuration of the carboxylic acids.
