Which of the Following Sugars is the Enantiomer of D-Mannose

Question

Which of the following sugars is the enantiomer of D-mannose?
A)L-mannose
B)D-glucose
C)D-galactose
D)L-arabinose

Accepted Answer

Enantiomers are mirror images of each other, and they have the same chemical formula and functional groups with different spatial arrangements. D-mannose has the same chemical formula as L-mannose, but their spatial arrangements are mirror images of each other. Therefore, L-mannose is the enantiomer of D-mannose.
