Given below are two statements I and II. Statement I : Dumas method is used for estimation of “Nitrogen” in an organic compound. Statement II : Dumas method involves the formation of ammonium sulphate by heating the organic compound with conc H2SO4. In the light of the above statements, choose the correct answer from the options given below

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

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

Solution

Statement I is incorrect because the Dumas method is actually used for estimating nitrogen in organic compounds through combustion, not by forming ammonium sulfate. However, Statement II is correct as it accurately describes the process of forming ammonium sulfate when heating organic compounds with concentrated sulfuric acid.
