Concept explainers
(a)
Interpretation:
The resonance contributor for the given cation is to be stated.
Concept introduction:
The delocalization of lone pair or free electrons from one place to another is known as resonance. The stability of compound depends upon the number of resonating structures. More the resonating structures of compound more will be its stability.
An electron deficient carbon atom that can accept the incoming nucleophile is known as carbocation. Carbocation shows resonance structures when double bond is present in conjugation with it.
(b)
Interpretation:
The resonance contributor for the given free radical is to be stated.

- Phenanthrene has five resonance structures, one of which is shown. Draw the other fourarrow_forwardCurrent Attempt in Progress For the given cation, draw all significant resonance forms and rank them from most significant to least significant. Briefly explain the rankings. Part 1 Ⓒ H Because this is a charged species, let's focus on resonance patterns that can delocalize the charge. First, add curved arrow(s) to show the resonance using the following pattern: a lone pair next to a carbocation. Modify the second structure given to draw the new resonance structure. Include relevant formal charges in your structure. Use the + and tools to add/remove charges to an atom, and use the single bond tool to add/remove double bonds.
