Question

What is the major product in the following reaction?
$C_{6}H_{5} — CH = CH — CH_{3} \xrightarrow[{H_{2}O}]{ (i)(CH_{3}COO)_{2}Hg }\,\xrightarrow[H_{3}O^{+}] {(ii)NaBH_{4} }$

• A.
• B.
• C. $C_{6}H_{5}CH_{2} — CH = CH_{2}$
• D.

Answer 1

Answer: (A)

In oxymercuration-demercuration reaction, Markownikoff's addition of $H_{2}O$ takes place with $HO^{-}$ added to carbon which can bear +ve charge of bridge cation
