Question

What is the product when glucose reacts with bromine water?

• A. Gluconic acid
• B. Glyceraldehyde
• C. Saccharic acid
• D. Oxime

Answer 1

The Correct Option is A

Upon reaction with bromine water, glucose undergoes a specific chemical transformation. Bromine water functions as an oxidizing agent, specifically targeting and oxidizing the aldehyde group (-CHO) of glucose into a carboxylic acid group (-COOH). This process is classified as a mild oxidation. The reaction is summarized by the equation:

C₆H₁₂O₆ (Glucose) + Br₂ + H₂O → C₆H₁₂O₇ (Gluconic Acid) + 2HBr

In its aldose form, glucose possesses an aldehyde group on its initial carbon, which is converted to a carboxylic acid, yielding gluconic acid. Consequently, gluconic acid is the resultant product when glucose reacts with bromine water.

Correct answer: Gluconic acid
