Question

Rewrite the following reaction by filling the blanks:

\[\ce{(CH3)2C = CHCH3 + HBr ->[peroxide] \underset{(major)}{\underline{}\underline{}\underline{}\underline{}} + \underset{(minor)}{\underline{}\underline{}\underline{}\underline{}}}\]

Answer 1

\[\begin{array}{cc}
\phantom{}\ce{CH3}\phantom{..................................}\ce{CH3}\phantom{.....................}\ce{CH3}\phantom{.....}\\
\phantom{}|\phantom{.....................................}|\phantom{.........................}|\phantom{.......}\\
\ce{\underset{2-Methyl but-2-ene}{CH3 - C - CH} - CH3 + HBr ->[peroxide] CH3 - CH - CH - CH3 + CH3 - C - CH2 - CH3}\\
\phantom{.....................................}|\phantom{...................}|\phantom{}\\
\phantom{.......................................}\ce{\underset{(major)}{\underset{2-Bromo-3-methyl butane}{Br}}} \phantom{..}\ce{\underset{(minor)}{\underset{2-Bromo-2-methyl butane}{Br}}}
\end{array}\]
