CHEM 2323 Study Guide - Newman Projection, Staggered Conformation, Eclipsed Conformation
Document Summary
Using those concepts, a newman projection is drawn with a circle representing a carbon, with substituents coming out of them. The substituents that are attached to the point in the circle are attached to that particular carbon (if a newman projection is looking between the c2-c3 bond, the point would represent c2). The substituents that are attached on the back end represent the back carbon: newman projection between c2-c3 bond, remember that compounds that are placed in anti conformation are the most stable and contain the least amount of energy. Compounds placed in a totally eclipsed conformation are the highest in energy and the least stable. Compounds that are in an anti position contain the largest substituents placed in a staggered conformation at an 180o angle from each other. Any other staggered position that places the largest substituents 60o is considered gauche. In a totally eclipsed confirmation, the largest substituents are directly behind each other.
