Chapter 1, Problem 1.21P

Interpretation Introduction

(a)

Interpretation:

A resonance structure of the given species is to be drawn.

Concept introduction:

Resonance structures differ in the position of electrons. The position of atoms remains the same. Curved arrows are used to show the movement of a pair of valence electrons. The formal charge on the atoms changes when the lone pair on an atom is converted to a bonding pair or a bonding pair is converted to a lone pair.

Interpretation Introduction

(c)

Interpretation:

A resonance structure of the given species is to be drawn.

Concept introduction:

Resonance structures differ in the position of electrons only; the position of atoms remains the same. Curved arrows are used to show the movement of a pair of valence electrons. The formal charge on the atoms changes when the lone pair on an atom is converted to a bonding pair or a bonding pair is converted to a lone pair.
