Make the reaction equation: butane-butene-butanol-butanal-butanol-butene-butanal

Here are the equations:
Н3С – СН2 – СН2 – СН3 = Н2 + Н2С = СН – СН2 – СН3 – dehydrogenation reaction, butene obtained;
Н2С = СН – СН2 – СН3 + Н2О = Н3С – СНОН – СН2 – СН3 – hydration, butanol is released;
C4H9 – OH + CuO = C4H8O + Cu + H2O – butanal formed;
Н3С – СН2 – СН2 – СНО + Н2 = Н3С – СН2 – СН2 – СНОН – reduction of butanal, butanol was obtained;
С4Н9ОН = С4Н8 + Н2О – butanol dehydration, butene formed;
C4H8 + H2O = C4H9 – OH – hydration, butanol was obtained;
С4Н9ОН + CuO = C4H8O + Cu + H2O – butanal formed.
These reactions confirm the presence of a bond between alkanes, alkenes, alcohols and aldehydes.
