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 answer
    A
    Statement I is false but Statement II is true
  • B
    Both Statement I and Statement II are false
  • C
    Both Statement I and Statement II are true
  • D
    Statement 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'.
