Find all of the chiral centers if any. I'm confused as to why some of the chiral center are considered chiral. I know that a chiral center is supposed to have four different substiuents. For 7.9 the first chiral center is connected to a H, a CH3, and 2 CH groups. For 7.10 both of the chiral centers are connected to a H, a CH3, and two CH groups.

Find all of the chiral centers if any. I'm confused as to why some of the chiral center are considered chiral. I know that a chiral center is supposed to have four different substiuents. For 7.9 the first chiral center is connected to a H, a CH3, and 2 CH groups. For 7.10 both of the chiral centers are connected to a H, a CH3, and two CH groups.

Expert Solution
Step 1

While considering the 4 groups attached to a C atom, we do not just consider the next C atom, rather we consider the whole group attached, whether the whole group is the same or different. 

So here in #7.9 and #7.10, although the next two carbon, -CH are the same, the groups as a whole are different. 

Hence they are chiral. 

How the groups as a whole are different is shown and explained below:
