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. Hydroboration-oxidation reagents yield the Markovnikov product of addition. Addition with acid and water as reagents allows sigmatropic rearrangements. Addition with acid and water as reagents avoids sigmatropic rearrangements. The reaction requires the Markovnikov product without sigmatropic rearrangement . Oxymercuration-demercuration reagents favor sigmatropic rearrangements. Oxymercuration-demercuration reagents prevent sigmatropic rearrangements. The reaction requires sigmatropic rearrangement. The reaction requires anti-Markovnikov product with sigmatropic rearrangement. 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.
