The correct statement is
Options
- AGlucose and mannose are C - 3 epimers
- BGlucose and galactose are C - 4 epimers
- CGlucose and fructose are anomers
- Dα - D - glucose and β - D - glucose are enantiomers
Correct answer
B. Glucose and galactose are C - 4 epimers
Step-by-step solution
Epimers are pair of diastereomers which differ in their configuration at only single chiral carbon. Example, glucose and mannose are C - 2 epimers(difference is at 2 n d carbon) and glucose and galactose are C - 4 epimers (differ at 4 t h carbon). Glucose and fructose are functional isomers and α - D - glucose and β - D - glucose are anomers.
