Concept explainers
(a)
Interpretation:
The incorrect information in the given resonance structure is to be stated.
Concept introduction:
Most of the organic structures cannot be represented using a single Lewis structure. Therefore, there exists more than one Lewis structure for representing a molecule or ion. These structures are known as resonance structures. These resonance structures combine together to give resonance hybrid that is lower in energy and is the most stable structure.
(b)
Interpretation:
The incorrect information in the given resonance structure is to be stated.
