Question:

Glucose is different from fructose as:

Options:

Does not undergo hydrolysis

Gives silver mirror with Tollen’s reagent

Is a monosaccharide

None of these

Correct Answer:

Gives silver mirror with Tollen’s reagent

Explanation:

The answer is (2) gives silver mirror with Tollen’s reagent.

Glucose and fructose are both monosaccharides, but they have different chemical properties. Glucose gives a positive test with Tollen's reagent, while fructose does not. This is because glucose has an aldehyde group, while fructose has a ketone group. The aldehyde group in glucose can react with Tollen's reagent to form a silver mirror.

The other options are incorrect. Option (1) is incorrect because both glucose and fructose undergo hydrolysis. Option (3) is incorrect because both glucose and fructose are monosaccharides. Option (4) is incorrect because there is a clear difference between glucose and fructose in terms of their reaction with Tollen's reagent.
