Maltose on treatment with dilute HCl gives:
  1. (A)D - Fructose
  2. (B)D - Galactose
  3. (C)D - Glucose and D - Fructose
  4. (D)D - Glucose✓ Correct

Answer: (D)

Solution

Maltose is a disaccharide of two D-glucose units joined by an -1,4 glycosidic linkage. Warming it with dilute hydrochloric acid hydrolyses that linkage, , so the only sugar obtained is D-glucose.
