Answer 2

1.The reaction of ethene with steam to form ethanol can be reversed. This allows ethanol to be converted into ethene. A catalyst of hot aluminium oxide is used to speed up the reaction.This is called a dehydration reaction.

enthanol→ethene+ steam

2.In a dehydration reaction, either a hydroxyl group from one molecule combines with a hydrogen atom from the other molecule, or two hydrogen atoms from one molecule combine with an oxygen atom on the other molecule.

3.In either case, water is released, and the two molecules are joined together.

4.When ethanol is heated with an excess of concentrated sulphuric acid at a temperature of 170°C, it produces ethene as final product. The concentrated acid acts only as a dehydrating agent and it is recovered unchanged.
