Teachers of organic chemistry insist that students learn the mechanisms of many common organic reactions. Computer-Aided Instruction (CAI) will require advanced techniques in order to evaluate student-drawn organic reaction mechanisms. Although CAI systems have been developed that allow the computer to evaluate student-drawn organic structures, there has not been a method to evaluate the “curved electron-pushing arrows” of Ingold, which have achieved universal usage in writing the descriptions of organic reactions. We will describe our progress towards the goal of computer evaluation of the “curved arrow” format for designating electron flow in organic reactions and its application to the classroom.
