An
(b)
Interpretation:
The steps to carry out the given transformation is to be shown.
Concept introduction:
An alkene can be converted to an alcohol in many ways, out of which, the oxymercuration-reduction, and an acid-catalyzed hydration reaction follows Markovnikov’s regiochemistry. The oxymercuration-reduction does not go through the carbocation intermediate, so no carbocation rearrangements occur with this mechanism. On the other hand, carbocation rearrangements are possible in acid-catalyzed addition of water. The product of oxymercuration-reduction is the one expected from Markovnikov’s rule, that is, the
