Vedclass · Answer

(B) The reaction sequence shown is Oxymercuration-Demercuration.In the first step,the alkene reacts with mercuric acetate $(Hg(CH_3COO)_2)$ in $THF$ and water to form an organomercury intermediate.In the second step,reduction with $NaBH_4$ in a basic medium $(NaOH)$ replaces the mercury group with a hydrogen atom.This process results in the Markovnikov addition of water across the double bond without carbocation rearrangement.Therefore,$X$ is $Hg(CH_3COO)_2$.

The reagent $X$ in the reaction sequence: $(CH_3)_3C-CH=CH_2$ $\xrightarrow[THF]{X} Y$ $\xrightarrow[NaOH]{NaBH_4} (CH_3)_3C-CH(OH)-CH_3$ is:
