Solution

Correct Answer:

Aldohexose

Glucose ( $C_{6} H_{12} O_{6}$ ) is classified based on its functional group and the number of carbon atoms:

Functional Group: It contains an aldehyde group ( $- C H O$ ) at $C_{1}$ , making it an Aldose.
Carbon Count: It contains 6 carbon atoms, making it a Hexose.

Combining these terms, glucose is an Aldohexose.
In contrast, Fructose is a Ketohexose (ketone group at $C_{2}$ , 6 carbons).

This easy difficulty chemistry question is from the chapter biomolecules, covering the topic of carbohydrates. It appeared in the 2025 exam.
