1.	Some oxidation reactions of methane are given below. Which of them is/are controlled oxidation reactions?(i) CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (l)(ii) CH4 (g) + O2 (g) → C (s) + 2H2O (l)(iii) CH4 (g) + O2 (g) +Mo2O3→ HCHO + H2O(iv) 2CH4 (g) + O2 (g) +Cu/523/100 atm→ 2CH3OH
Answer» (iii) CH₄ (g) + O₂ (g) +Mo₂O₃→ HCHO + H₂O (iv) 2CH₄ (g) + O₂ (g) +Cu/523/100 atm→ 2CH₃OH Reactions in which methane does not undergo complete combustion to give carbon dioxide and water or incomplete combustion to give carbon and water are controlled oxidation reactions.

Some oxidation reactions of methane are given below. Which of them is/are controlled oxidation reactions?(i) CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (l)(ii) CH4 (g) + O2 (g) → C (s) + 2H2O (l)(iii) CH4 (g) + O2 (g) +Mo2O3→ HCHO + H2O(iv) 2CH4 (g) + O2 (g) +Cu/523/100 atm→ 2CH3OH

Answer»

(iii) CH₄ (g) + O₂ (g) +Mo₂O₃→ HCHO + H₂O

(iv) 2CH₄ (g) + O₂ (g) +Cu/523/100 atm→ 2CH₃OH

Reactions in which methane does not undergo complete combustion to give carbon dioxide and water or incomplete combustion to give carbon and water are controlled oxidation reactions.
