Question

In which one of the following conversions, phosphorus pentachloride is used as a reagent?

पर्याय

• \[\ce{H2C = CH2 -> CH3CH2Cl}\]

• \[\ce{C2H6 -> C2H5Cl}\]

• \[\ce{CH3CH2OH -> CH3CH2Cl}\]

• \[\ce{C6H6 -> C6H5Cl}\]

Answer 1

\[\ce{CH3CH2OH -> CH3CH2Cl}\]

Explanation:

\[\ce{\underset{Ethyl alcohol}{CH3 - CH2 - OH} + PCl5 ->[\Delta] \underset{Ethyl chloride}{CH3 - CH2 - Cl} + \underset{Phosphorus oxychloride}{POCl3} + HCl}\]
