One could coalesce these into fewer concepts, which would focus upon electron or charge delocalization. One might alternatively suggest many more, particularly when advanced organic chemistry is considered. Why six? These suffice, individually or in combination, for many of the problems that arise during the study of organic chemistry. Pillars support a building, but do not represent its entirety. Furthermore, when one explains to students that six concepts will be sufficient for understanding a great deal of what they will learn, the intimidation of unlimited memorization of seemingly disconnected facts becomes less intimidating. Taber has reinforced this position, “It is therefore sensible, when teaching the subject, to remember to explicitly refer to the underlying principles, and not to assume that learners are recognizing the physical forces” (2). Referring to concepts repeatedly, particularly when there are relatively few key concepts and a novel presentation of them, may lead to increased student confidence and satisfaction
