Q.
The major product during hydroboration-oxidation of 1-methylcyclopentene is
NTA AbhyasNTA Abhyas 2020Hydrocarbons
Solution:
During hydroboration-oxidation, addition of $\text{H}_{2}\text{O}$ across the double bond occurs anti to Markownikoff's rule and since the stereochemistry of addition $\text{c}\text{i}\text{s}$ , therefore $$ $$ $\text{t}\text{r}\text{a}\text{n}\text{s}$ -2-methylcyclopentanol is formed
