Reduction of acetaldehyde with hydrogen. Ethanol is formed.
CH3 – COH + H2 → CH3 – CH2OH (ethanol).
In the presence of concentrated sulfuric acid and when heated, ethyl alcohol undergoes dehydration (the elimination of a water molecule), while converting into ethylene.
CH3 – CH2OH H2SO4 conc CH2 = CH2 + H2O (propylene).
Ethylene is characterized by a dehydrogenation reaction – the elimination of hydrogen. Ethylene is converted to ethyne (acetylene).
CH2 = CH2 – H2 → CH ≡ CH + H2.
Acetylenic hydrocarbons are characterized by a hydration reaction – the addition of water, and aldehydes are formed.
Acetylene forms acetaldehyde as a result of hydration.
CH ≡ CH + NOH = CH3 – SON.
