Chapter 14, Problem 14.52P

Interpretation Introduction

Interpretation:

Why alternating single and double bonds in the given hypothetical molecule are not considered to be conjugated is to be explained.

Concept introduction:

For alternating single and double bonds to be conjugated, the p orbitals of the double bonds must be parallel to each other. If the p orbitals are not parallel, then the overlap is too small for the double bonds to be considered conjugated.
