Q: What type of isomerism is exhibited by D-glucose and L-glucose?
Solution: D-glucose and L-glucose are enantiomers, differing in configuration at their chiral centers.
Steps: 5
Step 1: Understand what isomerism means. Isomerism is when two compounds have the same molecular formula but different structures or arrangements.
Step 2: Learn about enantiomers. Enantiomers are a type of isomer that are mirror images of each other.
Step 3: Identify D-glucose and L-glucose. Both are forms of glucose that have the same molecular formula (C6H12O6).
Step 4: Recognize that D-glucose and L-glucose differ in the arrangement of atoms around their chiral centers, which are specific carbon atoms in the molecule.
Step 5: Conclude that since D-glucose and L-glucose are mirror images of each other and differ at their chiral centers, they are classified as enantiomers.
