Undergraduate organic chemistry students are given a simple method to determine the stereochemical relationships between several molecules with more than one chiral center. The four groups around each chiral center are assigned Cahn-Ingold-Prelog priorities, and these numbers encircled in "bubbles". Subsequent structure manipulations by the allowed Fisher projection rotations involve only these four number bubbles to make R or S assignments. A table of relationships (identical, diastereomer, or enantiomer) between all the molecules is then generated.
Our Secondary School editors work hard to distill all the JCE materials to produce a fraction of particular interest to high school teachers. We call it CLIC.
In recent years we have worked hard to better match our advertisers with our readers. When shopping for chemistry education materials, visit our advertisers' WWW sites first.
Take JCE along on your outreach missions. Copies of the Journal, guest access to JCE Online, our publications catalog, and more are available for your participants.
