Concept explainers
a)
Interpretation:
- The given pairs of structures has to be predicted.
Concept Introduction:
Resonance Contributor: The appropriate structure with the localized electrons is called a resonance contributor, a resonance structure, or a contributing resonance structure.
Delocalized electrons: The sharing of electrons between two or more atoms known as delocalization of electrons. In order to have delocalized electrons, the system must be planar and have alternative double bonds and single bonds.
Resonance hybrid: The actual structure with delocalized electrons is called a resonance hybrid.

Interpretation:
- The given pairs of structures to be predicted.

In between? Answer these questions by completing the second and third columns in the table.arrow_forwardWhich of the following resonance structure for OCN- will contribute most to the correct structure of OCN-? O = C-N, with one lone pair on O and three lone pairs on N O=C=N, with two lone pairs on O, and two lone pairs on N O=C=N, with one lone pair on O, two lone pairs on C, and one lone pair on N O-C = N, with three lone pairs on O and one lone pair on N They All contribute equally to the structure on OCN-arrow_forward

- Consider the structure of the given ion. Lo What is an appropriate resonance structure of the ion? Select one: H-C - :0:arrow_forwardWhen drawing a resonance hybrid, how is the relative significance of individual resonance structures represented? O The entire resonance structure will be drawn larger or smaller, depending on its significance. O There is no way to note the significance of a resonance structure in atdrawing. The most significant resonance structure is circled. The partial charges will be written larger or smaller, depending on the significance of the resonance structure.
