Cahn-Ingold-Prelog priority rules to write the priority for all the four groups attached
to a chiral carbon
1. Give the highest priority to the atom with the highest atomic number, directly attached to the chiral carbon.
2. Consider the double bonds or triple bonds as two or three single bonds.
3. If two atoms directly attached to the chiral carbon are the same, then consider the next set of atoms, which is directly attached to the first atom.
4. If two isotopes are attached to the chiral carbon, then give the highest priority to the element with the highest mass number.
After giving the priority orders to the four groups attached to chiral carbon, keep the lowest priority group below the plane. If the remaining three substituents are in the clockwise direction, it has \(R\) configuration. If the remaining three substituents are in the counter-clockwise direction, it has \(S\) configuration.
Based on the above rules, the wedge-and-dash structure of the given compound is as follows:
