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.

- Draw all possible resonance structures for the following cation, and indicate which structure makes the largest contribution to the resonance hybrid.arrow_forwardidentify which is the most and least basic among the given. refer to the number and stability of their resonance structure.arrow_forwardWhich of the these statements is correct? O All of these statements are correct. O The greater the predicted stability of a resonance contributor, the more it contributes to the resonance hybrid. O A resonance hybrid is more stable than the predicted stability of any of its resonance contributors. O The greater the number of relatively stable resonance contributors, the greater the resonance energy.arrow_forward
- Draw the important resonance structures for the following ion.arrow_forwardCurved arrows are used to illustrate the flow of electrons. Using the provided resonance structures, draw the curved electron- pushing arrows to show the interconversion between resonance hybrid contributors. Be sure to account for all bond- breaking and bond-making steps. I I I I :O: farrow_forwardDraw additional resonance structures for each anion.arrow_forward
- 5. Draw the curved arrow(s) for converting the first resonance structures into the second resonance structures in the below moleules. (a) (b) :O:arrow_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.
