$CH_3-CH(CH_3)-CH_2-CH_2OH$

Vedclass · Answer

(A) $1$. $CH_3-CH(OH)-CH_3 \xrightarrow{PBr_3} CH_3-CH(Br)-CH_3$ $(X)$ (Isopropyl bromide).$2$. $CH_3-CH(Br)-CH_3 \xrightarrow{Mg, 	ext{dry ether}} CH_3-CH(MgBr)-CH_3$ $(Y)$ (Isopropyl magnesium bromide).$3$. $CH_3-CH(MgBr)-CH_3 + C_2H_4O ightarrow CH_3-CH(CH_3)-CH_2-CH_2-OMgBr$ $(Z)$ (Grignard reagent addition to epoxide).$4$. $CH_3-CH(CH_3)-CH_2-CH_2-OMgBr \xrightarrow{H_2O, \Delta} CH_3-CH(CH_3)-CH_2-CH_2OH + Mg(OH)Br$ (Hydrolysis).The final product is $3-methylbutan-1-ol$,which matches option $A$.

Consider the following reaction sequence:
$CH_3-CH(OH)-CH_3$ $\xrightarrow{PBr_3} (X)$ $\xrightarrow{Mg} (Y)$ $\xrightarrow{C_2H_4O (epoxide)} (Z)$ $\xrightarrow{H_2O, \Delta} ?$
What is the final product of this reaction?
