Question

Consider the following reaction:
$C{H}_4+2O_2\to C{O}_2+2H_{2}O$
Which of the following about the reaction given above is/are correct?
1. Carbon is oxidized.
2. Hydrogen is oxidized.
3. Hydrogen is reduced.
4. Carbon is reduced.
Select the correct answer using the code given below:

• A. 1 only
• B. 1 and 2 only
• C. 2 and 3 only
• D. 2 and 4 only

Answer 1

Answer: (B)

1 and 2 only

In the combustion of methane, carbon loses hydrogen and gains oxygen, so it is being oxidized. Oxygen gains hydrogen (and carbon), so it is being reduced. Hydrogen gains oxygen (and loses carbon), so it is being oxidized.

So option B is correct.
