Write the reaction equation: C4H8 – C4H10 – C4H9Cl – C4H9OH – C4H9OC2H5

Let’s execute the solution, compose equations for organic substances:
1.C4H8 + H2 = C4H10 – hydrogenation, butane obtained
2. С4Н10 + Cl2 = C4H9Cl + HCl – substitution, butane chloride, hydrogen chloride were formed;
3. С4Н9Cl + KOH = C4H9OH + KCl – exchange, butanol was released;
4. С4Н9ОН + CH3 – CH2 – ОН = С4Н9 – О – С2Н5 + Н2О – esterification occurs when heated in the presence of sulfuric acid, butane ethyl ester is obtained.
The above processes show the connection of saturated hydrocarbons (alkanes), alkenes, alcohols, ethers. The final product of the chain of transformations is used as a solvent.
