Concept: Bromine water is known to be a weak oxidising agent. It solely converts the glucose aldehydic group to carboxylic acid. In the chain, the other OH is unaffected. Another well-known fact about glucose is that it is a six-membered chain with just one aldehydic group.
We are aware that the chemical formula for glucose is

C 6 H 12 O 6

. It has six carbon atoms and one

C H O

group, making it a monosaccharide. Therefore, the

C H O

group will oxidise to

C O O H

COOH when bromine water, a weak oxidising agent, is introduced to glucose. The resultant substance is gluconic acid.
This chemistry shift can be expressed as:
