- In some nucleophilic substitutions under SN1 conditions, complete racemization does not occur and a small excess of one enantiomer is present. For example, treatment of optically pure 1-bromo-1-phenylpropane with water forms 1- phenylpropan-1-ol. (a) Calculate how much of each enantiomer is present using the given optical rotation data. (b) Whichproduct predominates—the product of inversion or the product of retention of conguration? (c) Suggest an explanation for this phenomenon.When 1,2-dimethylcyclopentene undergoes hydroboration–oxidation, one diastereomerof the product predominates. Show why this addition is stereospecific, and predict thestereochemistry of the major product.This is a Diels-Alder reaction between furan + maleic anhydride (endo and exo products). For each cycloaddition product, draw in all hydrogen atoms, and write the molecular formula below.
