Объяснение:

1) CH4 + Cl2 -> CH3Cl + HCl (hy)

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

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

CH3-CH2Cl + NaOH -> CH3-CH2-OH + NaCl

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

CH3-COH +Ag2O -> CH3COOH + 2Ag↓

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

CH3-CH2-CH2-CH2OH + CuO -> CH3-CH2-CH2-COH + Cu↓ + H2O

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