U.CAN Understand Curved Arrow Notation

These animations of organic reaction mechanisms developed by Grigoriy Sereda (Professor of chemistry) at the University of South Dakota have been used by many organic chemistry teachers around the world, contributed to the US National Science Library and Merlot database. Analysis of the resource's pedagogical impact has been published in Sereda G. Chem. Educator 10 2005 1, 46-49 DOI 10.1333/s00897050862a
