A Helpful Stereochemical Instructional Tool Even a t best, stereochemistry is not easily assimilated by most organic chemistry students. Devices such as molecular models, overhead projections, and balloons have their place in the inventive lecturer's storehouse of instructional tools which are useful in communicating stereochemical concepts. Nevertheless, many students are bewildered by the concept of right-hand and left-hand molecules, and by statements such as, "Stereoisomers which are not enantiomers are diastereoisomers."
