Determine the absolute configuration of the molecule shown below:

Question

Quizplus · Accepted Answer

The molecule is a chiral molecule with four different substituents around the central carbon atom. The priority of the substituents on the left side of the molecule is based on the atomic number of the atoms bonded to the central carbon atom, with the highest priority being given to the Cl atom. On the right side of the molecule, the priority is determined by comparing the first point of difference between the two substituents, which are the C and H atoms. Since the priority of the C atom is higher than that of the H atom, the CH2CH3 substituent has a higher priority than the CH3 substituent. Using the Cahn-Ingold-Prelog rules, we can determine that the molecule has an S configuration.
