Question

True statement for the acids of phosphorus $H_{3}P{O}_2,H_{3}P{O}_3$ and $H_{3}P{O}_4$ is :

• A. their acidic nature is : $H_{3}P{O}_4<H_{3}P{O}_3<H_{3}P{O}_2$.
• B. all of them are reducing in nature.
• C. all of them are tribasic acids.
• D. the geometry of phosphorus is tetrahedral in all the three.

Answer 1

The correct option is D the geometry of phosphorus is tetrahedral in all the three.

$H_{3}P{O}_4,H_{3}P{O}_3,H_{3}P{O}_2$ as $s{p}^3$ hybridised they all are tetrahedral.
