Solution
\[\begin{array}{cc}
\ce{H\phantom{....}H\phantom{...............}}\\
|\phantom{.....}|\phantom{...............}\\
\ce{CH3\underset{Propene}{- CH =} CH2 ->[Br2/CCl4][room temperature] CH3 - C - C - H ->[Zn] CH3 \underset{\overset{Propene}{(B)}}{- CH = C}H2 ->[dil.alkaline][KMnO4] CH3 - CH - CH2}\\
