a. Chiral. The carbon at the intersection is attached to four different substituents. It is the L stereoisomer because the —OH group is drawn on the left. The mirror image is drawn by reversing the —H and —OH groups on the chiral carbon.
CH2OHH OH CH3b. Achiral. The carbon atom at the intersection is attached to two identical groups (−CH3).
