Chemistry - Hydrogen and Its compound Question with Solution | TestHub

Set (C): Reaction (i) produces elemental H₂ gas at the cathode during the electrolysis of H₂SO₄(aq). Reaction (ii) reduces iodine and oxidizes peroxide to release elemental O₂ gas.

Set (D): Both reactions involve hydrogen peroxide (H₂O₂) acting as a reducing agent, which always oxidizes to form elemental O₂ gas as one of the products.

Sets (A) & (B): In set (A), reaction (i) yields methanol (CH₃OH), and in set (B), both reactions yield complex hydrides (LiBH₄ and LiAlH₄), meaning none of these reactions produce elemental forms.
