How would you convert of thanol into ethene?
Advertisements
उत्तर
Ethanol can be converted into ethene by the dehydration reaction.
The chemical equation for the above reaction is as follows:
CH3-CH2OH → CH2=CH2 + H2O
When ethanol is heated with concentrated sulphuric acid at 170oC, ethanol gets dehydrated to form ethene, an unsaturated hydrocarbon. Concentrated sulphuric acid acts as the dehydrating agent in this reaction.
