In order to exhibit delocalized π bonding, a molecule must have ________.
A)at least two π bonds
B)at least two resonance structures
C)at least three σ bonds
D)at least four atoms
E)trigonal planar electron domain geometry

Question

Quizplus · Accepted Answer

Delocalized π bonding occurs when there are multiple resonance structures that can be drawn for a molecule, indicating that the electrons are not localized on just one bond. Therefore, choice B, which states that the molecule must have at least two resonance structures, is the best choice. Choices A, C, D, and E are incorrect because they do not necessarily indicate delocalized π bonding.
