Question

hydrolysis of pcl5 produces?​

Answer 1

Answer:

hydrolysis proceeds completely to orthophosphoric acid: PCl5 + 4 H2O → H3PO4 + 5 HCl.

Explanation:

Answer 2

Answer:

$PCl_{5}$ on complete hydrolysis gives orthophosphoric acid $(H_{3}PO_{4})$, and, with insufficient amount of water it gives $POCl_{3}$ (phosphorus Oxychloride).

Explanation:

$PCl_{5}$ gives two types of hydrolysis reactions depending on the amount of water:

• With minute or insufficient quantities of water, it gives $POCl_{3}$ along with HCl
  $PCl_{5} + H_{2}O$ → $POCl_{3} + 2HCl$
• With an excess amount of water, it undergoes complete hydrolysis to produce orthophosphoric acid $(H_{3}PO_{4})$
  $PCl_{5} + 4H_{2}O$ → $H_{3}PO_{4} + 5HCl$
