Make up the reaction equations, with the help of which syntheses can be carried out in several stages: Methane – Propin

Let’s write down the solution:
1.CH4 – CH3Cl – C3H8 – C3H6 – C3H4;
2. Let’s write down the equations for the synthesis of organic substances:
CH4 + Cl2 = CH3Cl + HCl – methane chloride obtained;
CH3Cl + 2Na + C2H5Cl = C3H8 + 2NaCl – propane is released during the Würz reaction;
C3H8 = H2 + C3H6 – dehydrogenation, propylene was formed;
С3Н6 = Н2 + С3Н4 – propyne was obtained by dehydrogenation of propene.
The solution process shows the connection of saturated hydrocarbons with unsaturated ones, as well as with alkynes. End products: propyne, propene are used in the synthesis of polymers.
