Question

What is the product obtained when Br\(_2\) water reacts with glucose?

• A. Gluconic acid
• B. Saccharic acid
• C. 1, 6-dibromo glucose
• D. Bromhexane

Hint:

Bromine water reacts with glucose to form gluconic acid by oxidizing the aldehyde group of glucose.

Answer 1

The Correct Option is A

Step 1: Understanding the reaction.
When glucose reacts with bromine water, it undergoes oxidation to form gluconic acid. This is a common reaction of glucose with oxidizing agents like bromine.

Step 2: Analyzing the options.
(A) Gluconic acid: Correct — Gluconic acid is formed as a result of oxidation of glucose by bromine water.
(B) Saccharic acid: This is not the product of this reaction.
(C) 1, 6-dibromo glucose: This is incorrect; bromine does not add across the glucose molecule in this reaction.
(D) Bromhexane: This is an incorrect product.

Step 3: Conclusion.
The correct answer is (A) Gluconic acid.
