Question:

Write a balanced equation for the hydrolytic reaction of PCl5 in heavy water.

Answer:

In moist air ,PCl5 hydrolysis to POCl3 and finally gets converted to phosphoric acid.The reaction is as follows:

 

PCL5    +        H2O           →             POCl3      +   2HCl

                                               phosphorus oxychloride

 

POCl3    +       H2O         →            H3PO4      +  3HCl              

                                               phosphoric acid

 

But on treatment of PCl5 with heavy water (D2O) only phosphorus oxychloride if formed with the liberation of 2 molecules of deuterium chloride as a side product. The reaction involved is:

 

PCl5    +    D2O        →             POCl3         +     2DCl      

                                    phosphorus oxychloride
