The number of chiral carbons in chloramphenicol is

Answer: 2

Solution

A chiral carbon carries four different groups. In chloramphenicol the two adjacent carbons of the central chain — the one bearing the hydroxyl group and the one bearing the nitrogen — each meet this condition, while the remaining carbons do not, so the molecule has

2

chiral carbons.
