Vedclass · Answer

(D) The transformation involves converting $2,2-dimethylbutane$ to $3,3-dimethylbutan-1-ol$. Step $1$: Radical bromination using $Br_2, hv$ selectively replaces the hydrogen at the $C-3$ position to form $3-bromo-2,2-dimethylbutane$. Step $2$: Elimination using a bulky base like $t-BuO^-$ ($E_2$ mechanism) yields the less substituted alkene,$3,3-dimethylbut-1-ene$. Step $3$: Hydroboration-oxidation ($BH_3, THF$ followed by $H_2O_2, OH^-$) performs an anti-Markovnikov hydration of the terminal alkene to give the primary alcohol,$3,3-dimethylbutan-1-ol$. Thus,the correct sequence is $1$. $Br_2, hv$ $2$. $t-BuO^-$ $3$. $BH_3, THF$ $4$. $H_2O_2, OH^-$.
