Question

Identify the X and Y in the following reactions.

विकल्प

• \[\ce{X = Conc. HNO3, Y = H2SO4(SO3)}\]

• \[\ce{X = Conc. HNO3 + Conc. H2SO4, Y = H2SO4(SO3)}\]

• \[\ce{X = NaNO2/HCl, Y = H2SO4}\]

• \[\ce{X = Dil{.} HNO3, Y = SO3/H2O2}\]

Answer 1

\[\ce{X = Conc. HNO3 + Conc. H2SO4, Y = H2SO4(SO3)}\]

Explanation:

At 333 K, benzene produces nitrobenzene when it reacts with concentrated H₂SO₄ and concentrated HNO₃, whereas it produces benzene sulphonic acid when it reacts with SO₃ and concentrated H₂SO₄ (fumes) (Y).
