In the so-called Cahn-Ingold-Prelog (CIP) protocol (named after British chemists Robert Cahn and Sir Christopher Ingold and Swiss chemist Vladimir Prelog), one first assigns priorities to the four atoms attached to the stereogenic atom, in this case the carbon at the centre of the tetrahedron. The atom of ... WebThese are known as Cahn-Ingold-Prelog (CIP) rules after the people who developed the system. The first rule for very simple cases. You look first at the atoms attached directly to the carbon atoms at each end of the double bond - thinking about the two ends separately.
