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

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.
