Chapter 19, Problem 19.123CHP

Interpretation Introduction

Interpretation:

The structure activity relationship should be determined for the given phosphorus oxides.

Concept Introduction:

Phosphorus: It is a most abundant element of group 5A according for 0.10% of the mass of the earth crust.

Phosphorus oxides: Two phosphorus oxides, phosphorus(III) oxide $P_4{O}_6$ and phosphorus(V) oxide $P_4{O}_{10}$  and both oxides have structure based on the tetrahedral structure of elemental white phosphorus.

Phosphorus(III) oxide: It is a white crystalline solid that smells like garlic and has poisonous vapour.

Reaction of Phosphorus(III) oxide: This oxy acid react with ice water to produce a solution of the weak acid $H_{3}P{O}_3$ it known as phosphorus acid.

Phosphorus(V) oxide: It is a white flocculent power that can be prepared by heating elemental phosphorus in oxygen, it is very stable and poor oxidizing agent.
