Vedclass · Answer

(B) In hydroboration-oxidation reaction:$1$. The reaction involves the syn-addition of $BH_3$ across the double bond.$2$. The reaction proceeds through a concerted mechanism involving a four-membered cyclic transition state.$3$. The product obtained is an alcohol (specifically,an anti-Markovnikov alcohol),not a vicinal diol.$4$. The reaction follows the Anti-Markovnikov rule,but it is a syn-addition,not anti-addition.Therefore,statements $I$ and $II$ are correct.
