FREE Expert Solution

We are asked to identify the prioritization of the groups in the chiral center and to name the structure. 

First, we convert the structure to the bond-line to easily see the groups.

We can see that this is a chiral molecule because:

– there is no plane of symmetry present

– there is a chiral center present
