Осуществить цепочку превращения: 1) ch4→ch3oh→hcoh→hcooh→hcooch3→ch3oh 2) c3h7cl→c3h7oh→hcooh3h7→hcooh

1) CH4 -> CH3OH (O2)

   CH3OH + CuO -> HCOH + Cu + H2O

   HCOH + Ag2O -> HCOOH + 2Ag

HCOOH + HOCH3 = HCOOCH3 + H2O

HCOOCH3 + H2O = HCOOH + CH3OH

2) C3H7Cl + NaOH -> C3H7OH + NaCl

   C3H7OH + HCOOH -> HCOOC3H7 + H2O

  HCOOC3H7 + H2O= HCOOH + C3H7OH
