Computer Modeling of Nucleophilic Substitution and Beta Elimination Reactions

One of the more difficult topics covered in the standard organic chemistry courses involves unimolecular and bimolecular nucleophilic substitution and elimination reactions; SN1, SN2, E1, and E2. The understanding of these reactions is essential to an undergraduate's study of organic chemistry and is difficult to master by many students. The aims of this research project are twofold. First we hope to build a computer simulation model that successfully predicts which product is preferred (SN1 SN2 E1 or E2) given information on the reagent, substrate, temperature and solvent. Second, we hope to provide a model that helps the student have a greater understanding of these reactions by helping them organize the information needed to predict the preferred product, as well as being able to check their predictions with the model's predictions. Vensim® ( https://vensim.com/ ) simulation software is used to build our model because of its ease of use by students as well as s accessibility to all students (no licensing fee for educational use).
