Verified step by step guidance1
Understand that molecules capable of rotating plane polarized light are chiral. Chirality occurs when a molecule has a non-superimposable mirror image, often due to the presence of an asymmetric carbon atom.
Examine each molecule in the image for the presence of a chiral center. A chiral center is typically a carbon atom bonded to four different groups.
For molecule A, identify if there is a carbon atom bonded to four different groups, indicating a chiral center.
For molecule C, similarly, check for a carbon atom bonded to four different groups, which would make it chiral.
Conclude that molecules A and C are chiral and thus capable of rotating plane polarized light, based on the presence of chiral centers.
