प्रश्न

In which chemical reaction does carbon exhibit variation of oxidation state from - 4 to + 4? Write a balanced chemical reaction.

टीपा लिहा

उत्तर

In the combustion of methane, carbon exhibits variation from – 4 to + 4. The reaction is as follows:
\[\ce{CH4 + 2O2->CO2 + 2H2O}\]
In CH4, the oxidation state of carbon is – 4 while in CO2, the oxidation state of carbon is + 4.
