Concept explainers
(a)
Interpretation:
The curved arrows necessary to convert the resonance structure on the left to the one on the right in the given pair of structures are to be drawn.
Concept introduction:
A curved arrow is used to be show the movement of electrons. The arrow must start on an electron-rich atom or region and end on an electron-poor atom. If the movement is of a pi bond pair, the arrow should start from the center of the bond. Similarly, if it results in the formation of a pi bond, it should end between the two atoms.
(b)
Interpretation:
The resonance structure which contributes more to the hybrid is to be determined.
Concept introduction:
The resonance hybrid looks most like the lowest energy (more stable) resonance structure. Generally, the resonance structure is most stable when all non-hydrogen atoms have an octet, more covalent bonds and no atoms with nonzero formal charges. The resonance structure is more stable with fewer atoms possessing nonzero formal charges because uncharged species are inherently more stable than the corresponding charged species.
