The concepts section includes valence bond theory, conformational analysis of alkanes, and one stereochemistry animation. The molecules in motion section has 8 animations, both acyclic and cyclic compounds. Also some intermediates are included (tert-butyl radical and allyl radical). Each animation has an accompanying text that drills down to the main features of each reaction or concept. These are short, quick to find, descriptions with important information regarding each reaction or concept. For each reaction, text descriptions include electron pushing diagrams.
