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
  1. Statement I is false but Statement II is true
  2. Both Statement I and Statement II are false
  3. Both Statement I and Statement II are true
  4. 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
$\begin{gathered}2-3 \mathrm{~atm} \\ 100^{\circ} \mathrm{C}\end{gathered}$
