Write the reaction equation: Carbon-Methane-Chloromethane-Propane

С + 2Н2 = СН4 – the reaction of the compound occurs in hydrogen vapor with the participation of the Pd catalyst, methane is released;
CH4 + Cl2 = CH3Cl + HCl – substitution is possible in the light, chloromethane is obtained;
CH3Cl + 2Na + C2H5Cl = C3H8 + 2NaCl – propane was formed during the Würz reaction, which serves to lengthen the carbon chain.
The above reactions confirm the relationship between inorganic and organic substances, as well as between substances of the alkane class. The obtained substances have applications, for example, methane chloride, are used in industry as a solvent. Methane and propane are used as fuels.
