Carry out a chain of transformations propanol-propene-propane-bromopropane-hexane-carbon dioxide

Let’s carry out the solution of the chain of transformations:
Н3С – СН2 – СН2 – ОН = Н2О + Н3С – СН = СН2 – dehydration reaction, propene was obtained;
Н3С – СН2 = СН2 + Н2 = Н3С – СН2 – СН3 – addition, propane was formed;
Н3С – СН2 – СН3 + Br2 = H3C – CH2 – CH2Br + HBr – substitutions, bromopropane was released;
2Н3С – СН2 – СН2Br + 2Na = C6H14 + 2NaBr – Wurtz reaction, hexane was formed;
С6Н14 + 9О2 = 6СО2 + 6Н2О – combustion, carbon dioxide is released.
The reactions confirm the connection of alcohols, alkenes, alkanes. Hexane is used as a fuel in petroleum products.
