Question

In the reaction \[ \text{Br}_2 + 6 \text{CO} \to 3 \text{H}_2 + \text{Br}^+ + 3 \text{CO}_3 \]

• A. Bromine is reduced and oxidised.
• B. Bromine is reduced and water is oxidised.
• C. Bromine is neither reduced nor oxidised.
• D. Bromine is both reduced and oxidised.

Hint:

In redox reactions, a substance that both gains and loses electrons is considered to be both reduced and oxidized.

Answer 1

The Correct Option is D

Step 1: Identify oxidation states.
In the reaction, bromine undergoes both reduction (gains electrons) and oxidation (loses electrons). Therefore, bromine is both reduced and oxidised.
Thus, the correct answer is (4).
