Chapter 12, Problem 43P

Interpretation Introduction

Interpretation:

From the two resonance forms of calicene, the better correspond to the electron distribution in the molecule is to be determined and the reason for the statement that this form is more important than the other is to be explained and the compound which is more stabilized to greater extent is to be determined.

Concept introduction:

Electrostatic potential maps represent the charge distribution in a molecule using different colors. A region of red color represents higher negative charge while that of blue color represents higher positive charge.

In molecules containing rings, a resonance form that gives the ring(s) aromatic character is more stable than other forms.
