Question:
Which one of the following statements is not correct?
Which one of the following statements is not correct?
Show Hint
Glucose + bromine water gives gluconic acid. Glucose + strong oxidising agent like \(HNO_3\) gives saccharic acid.

- All monosaccharides are reducing sugars.
- Lactose is commonly known as milk sugar.
- Glucose pentaacetate does not react with hydroxylamine.
- Glucose does not give 2,4-DNP test.
- Glucose on oxidation with bromine water, gives saccharic acid.

The Correct Option is
Solution and Explanation
Concept:
Bromine water is a mild oxidising agent. It oxidises the aldehyde group of glucose to gluconic acid, not saccharic acid.
Step 1: Oxidation with bromine water.
Glucose with bromine water gives: \[ \text{Gluconic acid} \]
Step 2: Formation of saccharic acid.
Saccharic acid is formed when glucose is oxidised strongly, for example by nitric acid.
Step 3: Identify incorrect statement.
Therefore, statement (E) is not correct.
