Question

The number of chiral carbon centers in the following molecule is ............... 

Hint:

To identify chiral centers, look for carbons attached to four different groups. A quick way to check is to ensure the carbon is not part of a symmetry axis.

Answer 1

To determine the number of chiral centers in a molecule, we need to identify the carbon atoms that are attached to four different substituents. A chiral carbon center is one that has four different groups attached to it.
By examining the structure of the given molecule, we can identify the chiral centers:
1. The carbon in the ring with the N and O groups attached, where the other two groups are different.
2. Any other carbon in the structure that has four different substituents.
After examining the structure, we find that there are two chiral centers in the molecule.
Final Answer: \[ \boxed{2} \]
