QNEET-2020-Ch-667: NEET 2020 Chemistry - Class 12 NEET-2020-Ch-667 Solution: Sucrose on hydrolysis gives: \( \)-D-Glucose + \( \)-D-Glucose…
Sucrose on hydrolysis gives: -D-Glucose + -D-Glucose -D-Glucose + -D-Fructose -D-Fructose + -D-Fructose -D-Glucose + -D-Fructose
Multiple Choice Options
- A _ -D-Glucose + _ -D-Glucose
- B _ -D-Glucose + _ -D-Fructose
- C _ -D-Fructose + _ -D-Fructose
- D _ -D-Glucose + _ -D-Fructose
Step-by-Step Verified Solution
Sucrose is a disaccharide composed of two monosaccharide units, glucose and fructose, joined together via a glycosidic bond. Upon hydrolysis, this bond is broken, and the two constituent monosaccharides are released. Hydrolysis of sucrose results in the formation of one molecule of glucose and one molecule of fructose. However, it is important to specify the configurations of these monosaccharides as they exist in specific forms.
Sucrose _ H y d r o l y s i s
_ -D-Glucose + _ -D-Fructose
Glucose in sucrose is in the _ -D form while fructose is in the _ -D configuration. Thus, the correct answer reflecting the products of sucrose hydrolysis is:
Option B: _ -D-Glucose + _ -D-Fructose
This reflects the correct stereochemistry and identity of the monosaccharides produced from the hydrolysis of sucrose.
