Which of the following statements is correct ?
Show Hint
- Gluconic acid can from cyclic (acteal/hemiacetal) structure
- Gluconic acid is a partial oxidation product of glucose
- Gluconic acid is obtained by oxidation of glucose with (HNO3)
- Gluconic acid is a dicarboxylic acid.
The Correct Option is B
Solution and Explanation
Step 2: Statement (A) is wrong: gluconic acid has no free aldehyde/ketone group, so it cannot form a cyclic hemiacetal.
Step 3: Statement (C) is wrong: oxidation with HNO3 oxidises both the CHO and the terminal CH2OH, giving saccharic (glucaric) acid, not gluconic acid.
Step 4: Statement (D) is wrong: gluconic acid has only one -COOH group (monocarboxylic).
Answer: (B) Gluconic acid is a partial oxidation product of glucose

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:
