Featured Molecules: Crystal Violet, Fluorenone, and Fluorene
William F. Coleman
Chemistry Department, Wellesley College, Wellesley, MA 02481
Cover
September 2003
Vol. 80 No. 9
p. 1094
Full Text
The WebWare molecules of the month for the month of September are discussed in the article by Gail Horowitz, “A Discovery Approach to Three Organic Laboratory Techniques: Extraction, Recrystallization, and Distillation”. In the extraction part of the experiment, students use aqueous washes to remove a highly polar colored contaminent (crystal violet) or a nonpolar colored contaminent (fluorenone) from a desired compound (fluorene).

Fully manipulable (Chime) versions of these and other molecules are available at Only@JCE Online.
