Solution
Solution Steps
Step 1: Identify the molecular structures
Examine the molecular structures of the two compounds. Both molecules have the same molecular formula and the same connectivity of atoms.
Step 2: Determine the stereochemistry
Check the stereochemistry of the chiral centers in both molecules. The first molecule has the hydroxyl group (OH) and the hydrogen (H) on the chiral center in different spatial arrangements compared to the second molecule.
Step 3: Classify the relationship
Since the molecules have the same connectivity but differ in the spatial arrangement of atoms around the chiral center, they are stereoisomers. Specifically, they are diastereomers because they are not mirror images of each other.
