Propene is reacted first with hydrogen chloride to produce X which is then reacted with aqueous sodium hydroxide to give Y. Finally, Y is reacted with excess acidified potassium dichromate solution.

\[{\text{C}}{{\text{H}}_{\text{3}}}{\text{CHC}}{{\text{H}}_{\text{2}}}\xrightarrow{{{\text{HCL}}}}{\text{X}}\xrightarrow{{{\text{NaOH(aq)}}}}{\text{Y}}\xrightarrow{{{{\text{H}}^ + }/{\text{C}}{{\text{r}}_2}{{\text{O}}_7}^{2 - }{\text{(aq)}}}}{\text{Z}}\]
