Write the equations of chemical reactions: Butane = Butene1 = Butane = Ethene = ethyl alcohol = Ethene = Bromine ethane = Ethene = CO2

Let’s solve the chain of transformations:
C4H10 = C4H8 + H2 – dehydrogenation reaction, butene is formed;
С4Н8 + Н2 = С4Н10 – hydrogenation reaction, butene obtained;
C4H10 = C2H4 + C2H6 – decomposition, ethene and ethane are formed;
С2Н4 + НОН = С2Н5ОН – hydration reaction, ethanol was obtained;
С2Н5ОН = Н2О + С2Н4 – dehydrogenation reaction, ethene was obtained;
Н2С = СН2 + HBr = H3C – CH2 – Br – addition reaction, bromoethane is formed;
C2H5Br + KOH = C2H5OH + KBr – exchange, ethanol was obtained;
С2Н5ОН + 3О2 = 2СО2 + 3Н2О – combustion reaction, carbon monoxide is formed (4);
These reactions confirm the bond between alkanes, alkenes, alcohols, halogenated hydrocarbons.
