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

1. Both Statement I and Statement II are false
2. Statement I is false but Statement II is true
3. Statement I is true but Statement II is false
4. Both Statement I and Statement II are true

Correct answer: Statement I is false but Statement II is true

Solution

Statement I is incorrect because D-glucose pentaacetate does not react with 2,4-dinitrophenylhydrazine, which is typically used to detect carbonyl compounds, while Statement II is correct as starch can be hydrolyzed to glucose under the specified conditions with concentrated sulfuric acid.
