Hydrolysis of sucrose gives:

Hydrolysis of sucrose gives:

Options

  1. Aα−D−(+)−\alpha - D - ( + ) - Glucose and α−D−(−)\alpha - D - ( - )-Fructose
  2. Bα−D−(+)−\alpha - D - ( + ) - Glucose and β−D−(−)−\beta - D - ( - ) -Fructose
  3. Cα−D−(−)\alpha - D - ( - )-Glucose and β−D−(−)\beta - D - ( - )-Fructose
  4. Dα−D−(−)−Glucose\alpha - D - ( - ) - Glucose and α−D−(+)\alpha - D - ( + )-Fructose

Correct answer

B. α−D−(+)−\alpha - D - ( + ) - Glucose and β−D−(−)−\beta - D - ( - ) -Fructose

Step-by-step solution

Sucrose is a disaccharide of α−D−(+)−\alpha - D - ( + ) -Glucose and β−D−(−)−\beta - D - ( - ) -Fructose. So on hydrolysis we obtain α−D−(+)−\alpha - D - ( + ) -Glucose and β−D−(−)−\beta - D - ( - ) -Fructose.
