Question

Ch4->hcho ->ch3oh->ch3ce->c2h6->c2h5oh->ch3-cho->ch4

Answer 1

CH4 + O2 (k) -> H-COH +H2O
1)H-COH + H2-> CH3-OH
2)CH3-OH + HCl->CH3-Cl + H2O
3)2CH3Cl + 2Na -> C2H6 + 2NaCl
4)C2H6 + Cl2->C2H5Cl + HCl
C2H5Cl + KOH -> C2H5OH + KCl
5)C2H5OH CuO-> CH3-COH + Cu + H2O
6)CH3-COH + [O] -> CH3-COOH
CH3-COOH + KOH -> CH3-COOK + H2O
CH3-COOK + KOH (t) -> CH4 + K2CO3
