| $A$ $H _2 O / CH _2 Cl _2$ | $I$ Crystallization |
| $B$ $Image$ | $II$ Differential solvent extraction |
| $C$ Kerosene/Naphthalene | $III$ Column chromatography |

Correct match is : 
Propene $\xrightarrow{{C{l_2}/500\,{}^oC}}A\xrightarrow[{{\text{dryether}}}]{{Na}}B$
$B$ is
$C{H_2} = C{H_2}\xrightarrow{{HBr}}X\xrightarrow[{{I_2}(excess)}]{\begin{subarray}{l}
Hydrolisis \\
N{a_2}C{O_3}
\end{subarray} }Z$
