Which set of reagents is used for the Markovnikov addition of water to an alkene without rearrangement?

Question

Quizplus · Accepted Answer

The set of reagents used in choice C, Hg(OAc)2 followed by NaBH4 and NaOH, is commonly used for the Markovnikov addition of water to an alkene without rearrangement. The Hg(OAc)2 adds to the alkene to form a bridging mercurinium ion intermediate which is then reduced with NaBH4 to yield the alcohol product. The NaOH is used to hydrolyze the acetate group off the Hg(OAc)2. The other sets of reagents listed are either not used for the Markovnikov addition of water to an alkene or contain reagents that may cause rearrangement.
