Chapter 8, Problem 8.89QP

(a)

Interpretation Introduction

Interpretation: The lewis structures for formaldehyde molecule are to be drawn and formal charge on each atom is to be assigned and the structure more likely to exist is to be predicted. Whether the given two structures of formaldehyde are resonance forms of each other is to be stated.

Concept introduction: Formal charges play an important role in choosing between the possible molecular structures. The preferred structure is the one in which formal charges are zero.

To determine: The lewis structure for formaldehyde molecule and structure more likely to exist.

(b)

Interpretation Introduction

To determine: Whether the given two structures of formaldehyde are resonance forms of each other.
