Question

Accepted Answer

Column AColumn(A)Dehydrating nature3. CH3CH2OH + H2SO4 (Conc.) ⟶ H2C = CH2(B)Non- volatile acid (C)Acidic nature1. Na2SO3 + H2SO4 ⟶ Na2SO4 + H2O + SO2(D)Oxidising agent2. S + 2H2SO4 ⟶ 3SO2 + 2H2O

	Column A	Column
(A)	Dehydrating nature	1. Na₂SO₃ + H₂SO₄ ⟶ Na₂SO₄ + H₂O + SO₂
(B)	Non- volatile acid	2. S + 2H₂SO₄ ⟶ 3SO₂ + 2H₂O
(C)	Acidic nature	3. CH₃CH₂OH + H₂SO₄ (Conc.) ⟶ H₂C = CH₂
(D)	Oxidising agent
