Fructose is an example of :
Show Hint
- Heptose
- Pyranose
- Ketohexose
- Aldohexose
The Correct Option is C
Solution and Explanation
Its open chain structure is HOCH2-CO-(CHOH)3-CH2OH, with the carbonyl group as a ketone at C-2, so it is a ketose, not an aldose.
Hence fructose is a ketohexose. (Pyranose/furanose describe ring forms, not the class of sugar.)
Answer: (3) Ketohexose

Top JEE Main Questions
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
