Question

Which of the following reduces Tollen's reagent?

• A. Cane sugar
• B. Starch
• C. Glucose
• D. All of these

Answer 1

The correct option is C

Glucose

Explanation for the correct options:

(C) Glucose

• The chemical reagent used to distinguish between aldehydes, aromatic aldehydes, and ketones is known as Tollen's reagent.
• The reagent is consist of a solution of silver nitrate and ammonia.
• Glucose is an aldohexose monosaccharide and it is a reducing sugar.
• Thus, glucose can reduce Tollen's reagent.

Explanation for the incorrect options:

(A) Cane sugar

• Cane sugar is a non reducing sugar. Therefore, it cannot reduce Tollen's reagent.

(B) Starch

• Starch is not a reducing sugar, it cannot reduces Tollen's reagent

Hence, option (C) is correct, Glucose can reduce Tollen's reagent.
