Vedclass · Answer

(A) Oxymercuration-demercuration is a reaction that follows Markovnikov's rule for the addition of water across a double bond without rearrangement.For allylbenzene $(C_6H_5-CH_2-CH=CH_2)$,the electrophilic mercuric species attacks the terminal carbon $(CH_2)$ to form a more stable carbocation-like intermediate,followed by the attack of water at the more substituted carbon $(CH)$.This results in the formation of $1-$phenylpropan$-2-$ol as the major product.The reaction is: $C_6H_5-CH_2-CH=CH_2 \xrightarrow[(ii) NaBH_4]{(i) Hg(OAc)_2} C_6H_5-CH_2-CH(OH)-CH_3$.

The oxymercuration-demercuration of allylbenzene $(C_6H_5-CH_2-CH=CH_2)$ produces the major product:
