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 $$H_2 SO_4 $$. In the light of the above statements, choose the correct answer from the options given below

Statement I: Dumas method is used for estimation of nitrogen in an organic compound.

This is true. The Dumas method involves heating the organic compound with copper oxide (CuO) in an atmosphere of $$CO_2$$, which converts nitrogen in the compound to $$N_2$$ gas. The volume of $$N_2$$ collected is measured to estimate the nitrogen content.

Statement II: Dumas method involves the formation of ammonium sulphate by heating the organic compound with concentrated $$H_2SO_4$$.

This is false. The description in Statement II corresponds to the Kjeldahl method, not the Dumas method. In the Kjeldahl method, the organic compound is heated with concentrated $$H_2SO_4$$, which converts nitrogen to ammonium sulphate. The Dumas method uses CuO, not $$H_2SO_4$$.

The answer is Option A: Statement I is true but Statement II is false.
