Using this method, if ethene (an alkene) is added to steam, ethanol (an alcohol) can be formed. In fact, this method is an industrial way of making ethanol. |
As we saw in the previous topic, ethene undergoes an addition reaction with steam to form alcohol. C2H4 + H20 ———–> C2H5OH. |
Conversion of ethene to ethanol is an example of hydration reaction. In this reaction ethene is heated with steam in the presence of phosphoric acid. |
This type of addition reaction is called hydration. The water is added directly to the carbon – carbon double bond. |
