Помогите пожалуйста! Напишите цепочки реакций.

оправдываюсь за ногу в кадре

А) 2CH4 = HCCH+3H2
2HCCH = HCC-CH=CH2
HCC-CH=CH2+HCl = CH2=C(Cl)-CH=CH2
nCH2=C(Cl)-CH=CH2 = (-CH2-C(Cl)=CH-CH2-)n
б) 2C+H2 = HCCH
HCCH+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 = HCCH+Ca(OH)2
HCCH+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 = HCCH+Ca(OH)2
2HCCH+5O2=4CO2+2H2O
CO2+NH3 = NH2-C(O)-NH2
3HCCH = 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
