Vedclass · Answer

(D) $(1)$ Oxidation of the tertiary hydrogen in isobutane $(CH_3-CH(CH_3)-CH_3)$ by $KMnO_4$ yields tert-butyl alcohol $(A)$: $CH_3-C(OH)(CH_3)-CH_3$. $(2)$ Acid-catalyzed dehydration of $(A)$ with $H^{+}/\Delta$ yields $2$-methylpropene $(B)$: $CH_3-C(CH_3)=CH_2$. $(3)$ Anti-Markovnikov addition of $HBr$ to $(B)$ in the presence of peroxide $(ROOR)$ yields $1$-bromo-$2$-methylpropane $(C)$: $CH_3-CH(CH_3)-CH_2Br$.

$CH_3-CH(CH_3)-CH_3$ $\xrightarrow{KMnO_4} (A)$ $\xrightarrow[\Delta]{H^{+}} (B)$ $\xrightarrow[ROOR]{HBr} (C)$
Product $(C)$ in the above reactions is:
