Q43.Heating of 2-chloro-1-phenylbutane with EtOK/EtOH gives X as the major product. Reaction X with Hg(OAc)2/H2O followed by NaBH4 gives Y as the major product. Y is: (1) (2) (3) (4)
What This Question Tests
This is a multi-step reaction problem. It involves an E2 elimination with a strong base to form the major alkene product (X) according to Saytzeff's rule, followed by oxymercuration-demercuration on the alkene, which adds H and OH across the double bond following Markovnikov's rule without rearrangement.
