Объяснение:

1) CH4 + Cl2 -> CH3Cl + HCl   (hy)

CH3Cl + 2Na + ClCH3 -> CH3-CH3 + 2NaCl

CH3-CH3 + Cl2 -> CH3-CH2Cl + HCl  (hy)

CH3-CH2Cl + NaOH -> CH3-CH2OH + NaCl

CH3-CH2OH + CuO -> CH3-COH + Cu↓ + H2O

CH3-COH + Ag2O -> CH3COOH + 2Ag↓

2) CH3-(CH2)2-CH2Cl + NaOH -> CH3-(CH2)2-CH2OH + NaCl

CH3-(CH2)2-CH2OH + CuO -> CH3-(CH2)2-COH + Cu↓ + H2O

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