(Solved): A. Using the Cahn-Ingold & Prelog rules, identify with an asterisk (*) and specify with R and/or ...

Of the various ways that are known to separate enantiomers (process called resolution), the most used is the preparation and separation of diastereomers. A pair of enantiomers (in equal proportion are known as a racemic mixture) can be separated if they are chemically transformed into a pair of diasteroisomers by reacting them with an optically active compound. To give an example of this process, make the models of the two enantiomers of phenylethylamine (Figure 16). Now build the model of an optimally active acid that we will call $(+1?\mathrm{T}$ acid (Figure 17). In the resolution process, the acid $(+)?T$ is added to the racemic mixture of phenylethylamine and ercicios de práctica A.
