Make up the reaction equation: CH4 – CH3-CH3 – CH3-CH2-OH- -CH3-CH3

Let us write down the reaction equations for hydrocarbons:
CH4 + Cl2 = CH3Cl + HCl – substitution reaction, methane chloride was obtained;
2CH3Cl + 2Na = H3C – CH3 + 2NaCl – Wurtz reaction, ethane is formed;
Н3С – СН3 + Cl2 = H3C – CH2 – Cl + HCl – substitutions, chloroethane was released;
Н3С – СН2Cl + KOH = H3C – CH2 – OH + KCl – exchange, we got ethanol;
Н3С – СН2 – ОН = Н2О + Н2С = СН2 – dehydration, ethylene was formed;
Н2С = СН2 + Н2 = Н3С – СН3 – hydrogenation, ethane was obtained.
The reactions show the bond between alkanes, alcohols, alkenes. Halogenated hydrocarbons are the link between the classes and find practical application. Methane chloride, ethane chloride are used in chemistry as solvents.
