Question

On hydrolysis, $PC{I}_3$ gives :

• A. $H_{3}P{O}_3$
• B. $H_{3}P{O}_4$
• C. $POC{I}_3$
• D. $HP{O}_3$

Answer 1

The correct option is A $H_{3}P{O}_3$

$PC{l}_3$ on hydrolysis gives $HCl$ and $H_{3}P{O}_3$

$PC{l}_3+3H_{2}O\to H_{3}P{O}_3+3HCl$

Phosphorus trichloride reacts violently with water forming phosphorous acid.

Option (A) is correct .
