Chapter 9, Problem 9.101QP

(a)

Interpretation Introduction

Interpretation:

The electron-dot formula and resonance description for the given molecules has to be drawn.

Concept introduction:

Electron-dot structure, otherwise known as Lewis dot diagrams or electron dot structures that show the bond between atoms and lone pairs of electrons that are present in the molecule.  Lewis structure represents each atom and their position in structure using the chemical symbol.  Excess electrons forms the lone pair are given by pair of dots, and are located next to the atom.

Resonance:

The electron structure of a given molecule contains delocalized bonding via possible structure of all electron-dot formulas is known as resonance description.

One form of resonance stable structure is converted into other forms.  It possible in both single and multiple bonds containing molecule.  The electron-dot formulas differing only in the placement of single and double bonds
