NEET Chemistry Balancing Redox Reactions Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Oxidation in H2S reaction | (i) Hydrogen is removed from sulfur |
| (b) Reduction in Cl2 reaction | (ii) Chlorine gains hydrogen |
| (c) Oxidation in Al reaction | (iii) Oxygen is added to aluminium |
| (d) Reduction in Fe3O4 reaction | (iv) Iron is formed from oxide |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
In the reactions, H2S undergoes oxidation as hydrogen is removed from sulfur, and chlorine undergoes reduction as it gains hydrogen. Aluminium is oxidised due to the addition of oxygen, while iron is reduced from its oxide form to elemental iron.
