Answer
See Table 4-1 in book for picture
Answer: (2S,3S)-Isoleucine
Work Step by Step
1. Find the chiral center (a carbon with 4 different groups attached)
2. Order the groups in order of priority (H is lowest priority)
3. Determine if the direction of high priority to low priority around the chiral carbon is clockwise or counterclockwise
Clockwise = R
Counterclockwise = S
Use this, with the placement of the chiral centers, to name
