Chapter 10, Problem 56E

Interpretation Introduction

Interpretation:

The Lewis structure for each of the given molecule or ion is to be written. Resonance structures are to be included if necessary.

Concept Introduction:

Lewis model represents the molecules by the electron dot model which is based on the octet rule.

In ionic compounds, octet configuration is attained by the loss and gain of electrons.

In covalent compounds, octet configuration is acquired by sharing of electrons between the constituent atoms.

Lewis model represents the molecules by the electron dot model which is based on the octet rule.

While writing the Lewis structure of a covalent molecule, these steps are followed:

First, the correct skeleton is written for the molecule.

A total number of valence electrons are calculated.

Distributea total number of valence electrons in such a way that it completes the octet configuration of all the constituent atoms.

If any atom lacks the octet configuration the double or triple bonds are added.
