Question

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

\[ \begin{array}{|c|c|} \hline \textbf{LIST-I (Redox Reaction)} & \textbf{LIST-II (Type of Redox Reaction)} \\ \hline A. \, CH_4(g) + 2O_2(g) \rightarrow CO_2(g) + 2H_2O(l) & I. \, \text{Disproportionation reaction} \\ B. \, 2NaH(s) \rightarrow 2Na(s) + H_2(g) & II. \, \text{Combination reaction} \\ C. \, V_2O_5(s) + 5Ca(s) \rightarrow 2V(s) + 5CaO(s) & III. \, \text{Decomposition reaction} \\ D. \, 2H_2O(aq) \rightarrow 2H_2(g) + O_2(g) & IV. \, \text{Displacement reaction} \\ \hline \end{array} \]

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.
