Given below are two statements:
Statement I: D-glucose pentaacetate reacts with 2,4-dinitrophenylhydrazine.
Statement II: Starch, on heating with concentrated sulfuric acid at 100°C and 2-3 atmosphere pressure, produces glucose.
In the light of the above statements, choose the correct answer from the options given below:
Given below are two statements:
Statement I: D-glucose pentaacetate reacts with 2,4-dinitrophenylhydrazine.
Statement II: Starch, on heating with concentrated sulfuric acid at 100°C and 2-3 atmosphere pressure, produces glucose.
In the light of the above statements, choose the correct answer from the options given below:
Show Hint
- Both Statement I and Statement II are true
- Statement I is false but Statement II is true
- Statement I is true but Statement II is false
- Both Statement I and Statement II are false
The Correct Option is C
Solution and Explanation
Step 1: Statement I is true because D-glucose pentaacetate reacts with 2,4-dinitrophenylhydrazine to form a yellow-orange precipitate.
Step 2: Statement II is false because starch does not directly produce glucose by heating with concentrated sulfuric acid at 100°C; starch typically undergoes hydrolysis under such conditions.
Final Conclusion: The correct answer is Option (3), Statement I is true but Statement II is false.

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:
