Vedclass · Answer

(B) Hydroboration-oxidation is a reaction where $BH_3$ adds across a double bond.$1$. It involves $Syn$ addition of $H$ and $BH_2$ across the double bond.$2$. The reaction proceeds through a concerted mechanism involving a four-membered cyclic transition state.$3$. It follows Anti-Markovnikov regioselectivity,where the boron atom attaches to the less substituted carbon atom.Therefore,statements $I$ and $II$ are correct. Statement $III$ is incorrect because it follows Anti-Markovnikov rule,and statement $IV$ is incorrect because it is a $Syn$ addition.

In hydroboration reaction:
$I$. $Syn$ addition takes place
$II$. Reaction proceeds through formation of a cyclic transition state
$III$. Markovnikov rule is followed in the reaction
$IV$. Anti-addition takes place and anti-Markovnikov rule is followed
Which statement$(s)$ is/are correct?
