Question

Sucrose on hydrolysis gives

• A. two glucose units
• B. one glucose unit and one fructose unit
• C. one glucose unit and two fructose units
• D. one unit each of glucose, fructose and sucrose

Hint:

Sucrose is a disaccharide of glucose and fructose.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept
Sucrose is a disaccharide made of two monosaccharide units joined by a glycosidic bond.

Step 2: Hydrolysis
\(\text{C}_{12}\text{H}_{22}\text{O}_{11}+\text{H}_{2}\text{O}\rightarrow\text{C}_{6}\text{H}_{12}\text{O}_{6}+\text{C}_{6}\text{H}_{12}\text{O}_{6}\)
The products are D-glucose and D-fructose (invert sugar).

Step 3: Conclusion
One glucose unit and one fructose unit, option (B).

Final Answer:
Sucrose gives one glucose and one fructose, option (B). \[ \boxed{\text{(B) }\text{one glucose unit and one fructose unit}} \]
