There are several reagents that can be used to effect addition to a double bond including: acid and water, oxymercuration-demercuration reagents, and hydroboration-oxidation reagents. Inspect the final product and select all the reasons why acid in water was chosen to effect the following transformation instead of the other reagents. Complete the mechanism for the reaction by adding any missing atoms, bonds, charges, nonbonding electrons, and curved arrows. The reagents chosen for the transformation are: H3O+, H2O.
