Question- it has been shown that it is possible to react alkenes that are achirla with chiral catalyst to obtain products that are over 99% optically pure. Related to your studies in stereochemistry, suppose we perform one of these reactions on an alkene and obtain a product with an optical purity of 92.3%. The product consists of desired molecule and its enantiomer. Suppose you have 54 g of product. How much of each enantiomer do you have?
