Составьте уравнения реакций,при помощи которых можно осуществить следующие превращения: CH4→ C2H2→ CH3---COH→ CH3---CH2---OH→ CH3---CH2---Br→ CH3---CH2---OH→ CH3---COH→ CH3---COOH→ CH3---COONA

2CH4 = C2H2 + 3H2 C2H2 + H2O = CH3COH CH3COH + H2 = CH3-CH2-OH CH3-CH2-OH + HBr = CH3-CH2-Br + H2O CH3-CH2-Br + NaOH = CH3-CH2-OH + NaBr CH3-CH2-OH = CH3-COH + H2 CH3-COH + 2Cu(OH)2 = CH3-COOH + Cu2O + 2H2O CH3-COOH + NaOH = CH3-COONa + H2O
