Question

Sucrose on hydrolysis gives

• A. $\beta-D-Glucose$ + $\alpha -D-Fructose$
• B. $\alpha-D-Glucose + \beta - D - Glucose$
• C. $\alpha-D-Glucose + \beta -D-Fructose$
• D. $\alpha-D-Fructose + \beta -D-Fructose$

Answer 1

The Correct Option is C

Sucrose is a disaccharide composed of two monosaccharides, glucose, and fructose. To understand the hydrolysis of sucrose, let's go through the process step-by-step:

1. Definition of Hydrolysis: Hydrolysis is a chemical reaction in which a compound reacts with water, leading to the breakdown of that compound. In the case of sucrose, hydrolysis involves breaking the glycosidic bond between the glucose and fructose units.
2. Chemical Reaction: The hydrolysis of sucrose can be represented by the following chemical equation:

\(C_{12}H_{22}O_{11} + H_2O \rightarrow C_6H_{12}O_6 + C_6H_{12}O_6\)

1. Here, sucrose (\(C_{12}H_{22}O_{11}\)) reacts with water to yield glucose (\(C_6H_{12}O_6\)) and fructose (\(C_6H_{12}O_6\)).
2. Forms of Glucose and Fructose: On hydrolysis, the specific forms in which glucose and fructose are released are important to note. Sucrose hydrolyzes to give:
   • \(\alpha-D-Glucose\)
   • \(\beta-D-Fructose\)
3. Justification of Correct Option: Based on the information above, the correct answer to the question "Sucrose on hydrolysis gives" is \(\alpha-D-Glucose + \beta-D-Fructose\). This is because these are the specific forms of glucose and fructose obtained on the hydrolysis of sucrose.
4. Ruling Out Other Options:
   • \(\beta-D-Glucose + \alpha-D-Fructose\) is incorrect because the opening forms in sucrose are different.
   • \(\alpha-D-Glucose + \beta-D-Glucose\) is incorrect as fructose, not two glucose units, is produced.
   • \(\alpha-D-Fructose + \beta-D-Fructose\) is incorrect because glucose is one of the monosaccharides obtained alongside fructose.

Conclusion: The hydrolysis of sucrose results in the production of \(\alpha-D-Glucose + \beta-D-Fructose\). Hence, the correct answer is option 3.
