Помогите пожалуйста! Напишите цепочки реакций.

а) 2CH4 = HC≡CH+3H2 2HC≡CH = HC≡C-CH=CH2 HC≡C-CH=CH2+HCl = CH2=C(Cl)-CH=CH2 nCH2=C(Cl)-CH=CH2 = (-CH2-C(Cl)=CH-CH2-)n б) 2C+H2 = HC≡CH HC≡CH+H2 = CH2=CH2 3CH2=CH2+2KMnO4+4H2O = 3HO-CH2-CH2-OH+2KOH+2MnO2 5HO-CH2-CH2-OH+8KMnO4+12H2SO4 = 5HOOC-COOH+8MnSO4+4K2SO4+22H2O в) CaCO3=CaO+CO2 CaO+3C=CaC2+CO CaC2+2H2O = HC≡CH+Ca(OH)2 HC≡CH+H2O = CH3COH CH3COH+2Cu(OH)2 = CH3COOH+Cu2O+2H2O CH3COOH+Cl2 = Cl-CH2-COOH+HCl Cl-CH2-COOH+2NH3 = NH2-CH2-COOH+NH4Cl г) CaCO3=CaO+CO2 CaO+3C=CaC2+CO CaC2+2H2O = HC≡CH+Ca(OH)2 2HC≡CH+5O2=4CO2+2H2O CO2+NH3 = NH2-C(O)-NH2 3HC≡CH = C6H6 C6H6+Cl2 = C6H5Cl+HCl C6H5Cl+2NH3 = C6H5NH2+NH4Cl д) 2C+O2=2CO CO+2H2 = CH3OH CH3OH+CuO = HCOH+Cu+H2O 2nHCOH+nC6H5OH = (-CH2-C6H3OH-CH2-)n +nH2O 2CO+2H2 = CH3COOH CH3COOH+CH3OH = CH3COOCH3+H2O
