. Составьте уравнения реакций по схемам:

а) CaCO3 → CaC2 → C2H2 → → CH3COOH → CH4

б) → C2H5OH → C2H4 → (…-CH2-CH2-…)n

в) C2H6 → C2H5Br → C2H5OH → CH3COOH

а) CaCO3 + 4С = (t) 2CaC2 + 3COCaC2 + 2HCL = CaCL2 + C2H2C2H2 + H2O = (Hg 2+) CH3COHCH3COH + Ag2O = CH3COOH + 2AgCH3COOH + NaOH = CH3COONa + H2OCH3COONa + NaOH = CH4 + Na2CO3б) C2H5OH = (t, H2SO4) C2H4 + H2OC2H4 = (t, полимеризация, cat) ( ... - CH2- CH2-...)nв) C2H6 + Br2 = C2H5Br + HBrC2H5Br + NaOH (водный) = C2H5OH + NaBr5C2H5OH + 4KMnO4 + 6H2SO4 → 5CH3COOH + 2K2SO4 + 4MnSO4 + 11H2O
