Write the reaction equations with which you can obtain a) methyl acetate based on calcium carbide

Write the reaction equations with which you can obtain a) methyl acetate based on calcium carbide b) acetaldehyde based on methane c) propanoic acid based on ethane

Let’s write the equations:
a) CaC2 – C2H2 – CH3COH – CH3COOH – CH3 – COO – CH3;
CaC2 + 2H2O = Ca (OH) 2 + C2H2 – hydration reaction;
С2Н2 + Н2О = Н2С = СНОН = Н3С – СОН – acetaldehyde is released;
CH3 – СОН + Ag2O = CH3 – COOH + 2Ag – oxidation of aldehyde;
CH3 – COOH + CH3 – OH = CH3 – COO – CH3 + H2O – esterification, methyl acetate was obtained;
b) CH4 – C2H2 – CH3COH;
2CH4 = C2H2 + 3H2 – decomposition reaction;
С2Н2 + Н2О = Н2С = СН – ОН = СН3 – СОН – acetylene hydration;
c) C2H6 – C2H5Cl – C3H8 – C3H7Cl – C3H7OH – H3C – CH2 – COH – H3C – CH2 – COOH;
C2H6 + Cl2 = C2H5Cl + HC – substitution reaction;
C2H5Cl + 2Na + CH3Cl = C3H8 + 2NaCl – propane is released during the Würz reaction;
C3H8 + Cl2 = C3H7Cl + HCl – substitution, chloropropane was formed;
С3H7Cl + KOH = C3H7OH + KCl – exchange, propanol is released;
С3Н7ОН + CuO = H3C – CH2 – COH + Cu + H2O – propanol oxidation, propanal was obtained;
Н3С – СН2 – СОН + Ag2O = H3C – CH2 – COOH + 2Ag – propionic acid and silver were obtained.
