Concept:Alkenes are unsaturated hydrocarbons that undergo addition reactions to form saturated products like alkanols.
Explanation:In this reaction, the double bond of the alkene breaks open.
A water molecule adds across the double bond, with the
−OH group attaching to one carbon atom and a hydrogen atom to the other.
This process is known as hydration and is a typical electrophilic addition reaction.
No atoms are removed from the alkene, so it is not elimination or substitution.
The oxidation state of carbon does not change significantly, so it is not classified as a redox reaction here.
Answer:D. Addition reaction
