Answer #1

Optically pure compounds are those compounds when only one enantiomer exists. It is either dextrorotatory or leavorotatory. In case of optically pure compounds, enantiomeric excess is 100%. Racimic compounds are those compounds where (+) enantiomer and (-) enantiomer are present in equal amount (1:1). In case of racimic compounds, enantiomeric excess is 0%. Scalemic mixture is a mixture of enantiomers at a ratio other than 1:1. Enantiomeric excess of scalemic mixture is from 0% to 100%.

In this experiment a racemic mixture of a diamine called trans-1,2-diaminocyclohexane (basic substances) was converted to a diastereomeric salt mixture using optically pure L-(+)-tartaric acid. This salt mixture will be separated using crystallization techniques. The salt from the (R,R) diamine was less soluble than the salt from the (S,S) diamine and was separated by a vacuum filtration. How could you convert your salt back to the free diamine? Describe the experimental details that would be needed to regenerate your optically...
