1.	Consider the following reaction : CH_(4)+2O_(2) to CO_(2) + 2H_(2)O Which of the following about the reaction given below is/are correct ? 1. Carbon is oxidized ( कार्बन का ऑक्सीकरण ) 2. Hydrogen is oxidized ( हइड्रोजन का ऑक्सीकरण ) 3. Hydrogen is reduced ( हाईड्रोजन का अपचयन ) 4. Carbon is reducedSelect the correct answer using the code given below :
Answer» 1 only 1 and 2 only 2 and 3 only 2 and 4 only Solution :Oxidation : Gain of oxygen or LOSS of hydrogen, Loss of electrons or increase in oxidation state Reduction: Gain of hydrogen or loss of oxygen, Gain of electrons or DECREASE in oxidation state . 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.
