Continue Reading 3 3 Sponsored by Gundry MD WebFeb 4, 2015 · You cannot have a chiral carbon that doesn't have 4 groups attached to it (i.e. must be sp3 hybridized). If you think you've found a chiral carbon that only has 3 groups attached to it, you're probably forgetting the unwritten hydrogen. In this example specifically, there is only one chiral carbon, the one attached to the secondary alcohol.
