Question

Match the LIST-I with LIST-II (Redox Reactions).

Choose the correct answer from the options given below:

• A. A-IV, B-I, C-II, D-III
• B. A-II, B-III, C-IV, D-I
• C. A-II, B-III, C-I, D-IV
• D. A-III, B-IV, C-I, D-II

Hint:

In redox reactions, keep track of oxidation states to determine the type of reaction (combination, displacement, etc.).

Answer 1

The Correct Option is C

Step 1: The reaction \( CH_4 + O_2 \) is a combination reaction (A-II).
Step 2: The reaction \( 2NaH \rightarrow 2Na + H_2 \) is a decomposition reaction (B-III).
Step 3: The reaction \( V_2O_5 + Ca \) is a redox displacement reaction (C-I).
Step 4: The reaction \( 2H_2O \rightarrow 2H_2 + O_2 \) is a displacement reaction (D-IV).
Final Conclusion: The correct matching is Option (3), A-II, B-III, C-I, D-IV.
