Q1 / 75 · JEE Main 2025 (28 Jan Shift 1) · Chemistry
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 $100^{\circ} \mathrm{C}$ and 2-3 atmosphere pressure produces glucose.
In the light of the above statements, choose the correct answer from the options given below
- Correct answerAStatement I is false but Statement II is true
- BBoth Statement I and Statement II are false
- CBoth Statement I and Statement II are true
- DStatement I is true but Statement II is false
Solution
- D-glucose pentaacetate do not react with 2.4 DNP
- Starch $\frac{\text { conc. } \mathrm{H}_2 \mathrm{SO}_4}{\Delta}$ Glucose
$\begin{gathered}2-3 \mathrm{~atm} \\ 100^{\circ} \mathrm{C}\end{gathered}$
Hence, the correct answer is option: 'A'.
