A derivative of glycopyrollate, a medication often administered before a patient's surgery, is shown below. How many chiral centers are there in the molecule?

Question

Quizplus · Accepted Answer

There are two chiral centers in the molecule, indicated by the asterisks (*) in the image below:
 
A chiral center is an atom (usually carbon) that is bonded to four different groups. In this molecule, both carbon atoms with asterisks have four different groups (two hydrogens and two different branches of the molecule) bonded to them, making them chiral centers.
