Question “Add curved arrows to both structures to show the delocalization of electron pairs needed to form…”
Add curved arrows to both structures to show the delocalization of
electron pairs needed to form the other resonance
contributor.
Answer
This problem is based upon the concept of resonance.
There are two resonating structures. Two resonating structures are given. One structure has curved arrows. The curved arrows of the other structure must be added to show delocalization of electron pairs necessary to form the second resonance contributor.
Resonance is a phenomenon whereby a single Lewis structure cannot explain bonding in a compound. Due to delocalization electrons (lone pairs or $math_tag_0), many resonating structures can be created in a single compound.
Below is the structure of the first resonance form.
