Chapter 7, Problem 39QAP

Interpretation Introduction

(a)

Interpretation:

The Lewis structure of peroxypropionyl nitrate (PPN) needs to be depicted.

Concept introduction:

• A Lewis dot structure depicts bonding between atoms in a molecule in terms of the valence electrons, bonding electron pairs as well as the lone pairs surrounding individual atoms.

Interpretation Introduction

(b)

Interpretation:

The ideal bond angles in PPN need to be indicated.

Concept introduction:

• In molecules with more than 2 atoms, the angle formed between 2 bonds is called as the bond angle.
• The ideal geometry adopted by various molecules can be predicted based on the valence shell electron pair repulsion (VSEPR) theory. As per the VSEPR model, an orbital arrangement which minimizes valence electron repulsion leads to a stable geometry.
