Объяснение:

CH4 + Cl2 -> CH3-Cl + HCl  (hy)

CH3Cl + 2Na + Cl-CH3 -> CH3-CH3  + 2NaCl

CH3-CH3 -> CH2=CH2 + H2  (t,kat)

CH2=CH2 + H2O -> CH3-CH2-OH (kat)

CH3-CH2-OH + CuO -> CH3-COH + Cu↓ + H2O

CH3-COH +Ag2O -> CH3COOH + 2Ag↓

CH3-CH2-CH2-CH2-Cl + NaOH -> CH3-CH2-CH2-CH2-OH + NaCl

CH3-CH2-CH2-CH2-OH + CuO -> CH3-CH2-CH2-COH + Cu↓ + H2O

CH3-CH2-CH2-COH + Ag2O -> CH3-CH2-CH2-COOH + 2Ag↓
