Development of a Web-Based, Student-Centered Stereochemistry Tutorial

摘要

A Web-based stereochemistry tutorial is described that details the core definitions and structural representations of stereochemistry in an organic chemistry course. The Cahn?Ingold?Prelog rules and their application for assigning R and S orientations to stereocenters and E and Z orientations to alkenes are discussed. This tutorial is unique in allowing students to determine their preferred structural representation of organic molecules and select their own method for making stereochemical comparisons between these molecules. The remaining content of the comparison section of the tutorial is presented using the method that the student selected.
