Here you will find a brief introduction to both the cis/trans and the E/Z designations of configuration of double bonds. A hands-on guide to assist in the planning and execution of synthetic reactions in the laboratoryDespite the maturity of organic chemistry, it can still be very challenging to identify optimal methods for synthetic transformations that perform as well in real-world manufacturing processes as they do in the laboratory.

COSSU; O. DE LUCCHI; First Published: 12 March organic compounds are already known and a large number (about half a million) of new compounds are being added every year to the domain of organic chemistry. The study of such a vast subject would be unnecessarily complicated if it is not divided into classes or groups based on the similarities of structures and properties of the group members.
