Crotyl alcohol, $\text{CH}_3\text{CH}=\text{CHCH}_2\text{OH}$, is a colourless liquid and is used as a solvent. Under suitable conditions, crotyl alcohol reacts separately with $\text{Br}_2$, $\text{K}_2\text{Cr}_2\text{O}_7/\text{H}^+$, conc. $\text{KMnO}_4/\text{H}^+$ and $\text{PCl}_5$. Which row is the correct one?
- A$\text{Br}_2$, room temperature, $\text{CH}_3\text{CH}=\text{CHCH}_2\text{Br}$
- B$\text{K}_2\text{Cr}_2\text{O}_7/\text{H}^+$, heat under reflux, $\text{CH}_3\text{CH}=\text{CHCHO}$
- Cconc. $\text{KMnO}_4/\text{H}^+$, heat under reflux, $\text{CH}_3\text{CH}=\text{CHCO}_2\text{H}$
- D$\text{PCl}_5$, room temperature, $\text{CH}_3\text{CH}=\text{CHCH}_2\text{Cl}$
