VisChem topic 6: molecular structure, shape and polarity

This web page contains ten animations of molecules and compound ions as well as nine QTVR objects showing organic molecules. The animations rotate the molecules to show their structure fully. The QTVR objects can be manipulated by the user so that, as well as being rotated, different ways of modelling the molecules can be seen.

VisChem topic 10: reactions of carbon compounds

This web page contains animations showing reaction mechanisms for organic substitution, addition and elimination reactions. For most reactions there are two animations, one showing molecular models, and the other showing structural formulas with movement of electrons as bonds are rearranged.
