Question

Match List-I with List-II 



Choose the correct answer from the options given below:

• (A) (I), (B) (II), (C) (III)
• (A) (I), (B) (III), (C) (II)
• (A) (II), (B) (III), (C) (I)
• (A) (III), (B) (II), (C) (I)

Hint:

The oxidation state of carbon in formaldehyde is 0, in methanol is -2, and in formic acid is +2.

Answer 1

The Correct Option is A

- In methanol (A), the carbon atom has an oxidation state of \(-2\) due to the presence of the hydroxyl group, which reduces the carbon.
- In formaldehyde (B), the carbon atom has an oxidation state of 0.
- In formic acid (C), the carbon atom has an oxidation state of +2 because it is bonded to both an oxygen atom (via a double bond) and a hydroxyl group.
Conclusion:
Therefore, the correct matching is: \[\text{(A) (I), (B) (II), (C) (III)}\]
Final Answer: \[ \boxed{\text{(A) (I), (B) (II), (C) (III)}} \]
