Question:
$PCl_3$ reacts with water to form
$PCl_3$ reacts with water to form
Updated On: Jun 15, 2024
- $PH_3$
- $H_3PO_3, HCl$
- $POCl_3$
- $H_3PO_4$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
$PCl_3$ is easily hydrolysed by water to give $POCl_3$
and finally it gives $H_3PO_3$ and HC1.
$\, \, \, \, \, \, \, PCl_3 + H_2O \, \longrightarrow\, POCI_3 + 2HCI $
$\, \, \, POCl_3 + 3H_2O \, \longrightarrow\, H_3PO_3 + 3HCI $
and finally it gives $H_3PO_3$ and HC1.
$\, \, \, \, \, \, \, PCl_3 + H_2O \, \longrightarrow\, POCI_3 + 2HCI $
$\, \, \, POCl_3 + 3H_2O \, \longrightarrow\, H_3PO_3 + 3HCI $

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
