Solution
\[\begin{array}{cc}
\ce{H\phantom{....}H\phantom{...............}}\\
|\phantom{.....}|\phantom{...............}\\
\ce{CH3\underset{Propene}{- CH =} CH2 ->[Br2/CCl4][room temperature] CH3 - C - C - H ->[Zn] CH3 \underset{\overset{Propene}{(B)}}{- CH = C}H2 ->[dil.alkaline][KMnO4] CH3 - CH - CH2}\\
\phantom{........................................}|\phantom{.....}|\phantom{..............................................}|\phantom{......}|\phantom{..}\\
\ce{\phantom{.......................................}\underset{\overset{1,2-Dibromopropane}{(A)}}{Br\phantom{...} Br}\phantom{...........................................}\underset{\overset{Propane-1,2-diol}{(C)}}{OH\phantom{...}OH}}\end{array}\]
