Chapter 22, Problem 22.30CP

Interpretation Introduction

(a)

Interpretation:

The molecular formula and the non-oxygen atom of each oxide (which forms out of second and third row elements: $\text{C,N,O,F,Si,P,S,Cl}$ ) should be determined.

Concept introduction:

Oxygen forms many oxides with groups of $\text{4A}$, $\text{5A}$, $6\text{A}$ and $\text{7A}$ in the periodic table. The molecular structure and bonding are different in each group as the number of electrons in the outermost shell that participate in bonding (valence electrons) is different.

Interpretation Introduction

(b)

Interpretation:

Electron-dot structures of each oxide should be drawn and the availability of resonance structures for any of the oxides should be determined.

Concept introduction:

Electron-dot structures are used to represent a molecule’s bonding (by lines) and lone electrons that do not participate in bonding (by dots). For some molecules, there are several valid electron-dot structures which are known as ‘resonance’ structures.
