The hydration of ethylene can be modelled by the following process:
- Use molecular model kits to construct an ethylene molecule, a sulfuric acid molecule and a water molecule.
- Break open the double bond of the ethylene molecule and add a hydrogen atom from the sulfuric acid to one carbon atom, and the HSO₄ group to the other carbon atom, forming the molecule CH₃CH₂HSO₄.
- Break the water molecule into a hydroxy group and a hydrogen atom.
- Replace the HSO₄ group in the CH₃CH₂HSO₄ molecule with the hydroxy group.
- Combine the HSO₄ group with the hydrogen atom from the water to reform the sulfuric acid molecule.
The dehydration of ethanol can be modelled by simply reversing the above process
