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

When glucose reacts with bromine water, a specific type of chemical reaction occurs. Bromine water acts as an oxidizing agent and selectively oxidizes the aldehyde group (-CHO) present in glucose to a carboxylic acid group (-COOH). This type of reaction is a mild oxidation. The reaction can be represented as follows:

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

Glucose, in its aldose form, has an aldehyde group at the first carbon, which gets converted into a carboxylic acid, resulting in the formation of gluconic acid. Therefore, the product of the reaction between glucose and bromine water is gluconic acid.

Correct answer: Gluconic acid

Answer 2

When glucose reacts with bromine water, it undergoes oxidation. The bromine water (which contains Br₂) oxidizes the aldehyde group of glucose to a carboxylic acid group, resulting in the formation of gluconic acid.

• Gluconic acid is the product formed when the aldehyde group (–CHO) in glucose is oxidized to a carboxyl group (–COOH).
• This reaction occurs under mild conditions with bromine water, and no further oxidation occurs to form more complex products like saccharic acid.

Thus, the correct product is Gluconic acid (Option A).
