Showing Enantiomorphous Crystals of Tartaric Acid
Andrade-Gamboa, Julio
Journal of Chemical Education, v84 n11 p1783-1784 Nov 2007
Most of the articles and textbooks that show drawings of enantiomorphous crystals use an inadequate view to appreciate the fact that they are non-superimposable mirror images of one another. If a graphical presentation of crystal chirality is not evident, the main attribute of crystal enantiomorphism can not be recognized by students. The classic case of tartaric acid crystals is discussed and the use of an alternative graphical representation and a paper model is proposed to facilitate the conceptualization of this subject. (Contains 1 note and 3 figures.)
