Addition reaction between water molecules and alkene molecules produces alcohol.
<h3>What is addition reaction?</h3>
Addition reaction generally takes place across the unsaturated carbon compounds.
When water molecule (H₂O) is added to the alkene which may be ethene (C₂H₄) molecule then formation of product i.e. ethanol (CH₃CH₂OH) takes place through the addition of hydrogen and hydroxyl group across the double bond. And reaction is shown in the attached image.
Hence formation of alcohol product takes place.
