Which Among These Species Does Not Exhibit Resonance?

Click For Summary

Discussion Overview

The discussion revolves around identifying which of several chemical species does not exhibit resonance. Participants explore the concept of resonance in organic compounds, seeking clarification and assistance in drawing resonance structures.

Discussion Character

  • Homework-related
  • Exploratory

Main Points Raised

  • One participant lists four chemical species and asks which one does not exhibit resonance, seeking explanations for the reasoning.
  • Another participant expresses uncertainty and suggests that option 3 (1,4-Cyclohexadiene) is the correct answer due to difficulty in drawing resonance structures for it.
  • Further replies question the resonance structures drawn for the other options, indicating confusion about the nature of resonance in these compounds.
  • Some participants express frustration over their inability to convey their drawings and conclusions effectively, emphasizing the urgency of their request for help.
  • A participant emphasizes that while they could not draw branches in resonance structures, they still believe the other options exhibit resonance.
  • A final reply indicates a need for proper attempts at solutions before seeking help, suggesting that the thread should be moved to a more appropriate section for homework inquiries.

Areas of Agreement / Disagreement

Participants do not reach a consensus on which species does not exhibit resonance, with multiple views expressed regarding the ability to draw resonance structures for the listed compounds. The discussion remains unresolved.

Contextual Notes

Participants express limitations in their understanding and ability to represent resonance structures visually, which affects their contributions to the discussion.

Among the following species, which one does not exhibit resonance?
1. CH2=CH-CΘH2 (the 3rd carbon has a -ve charge)
2. CH2=CHCl
3. 1,4-Cyclohexadiene
4. CH3-NO2
Please, can anyone tell me which one and how did you get it?

I believe it's option 3 because that's the only compound I'm not able to draw resonance structures for. But I still have doubt with the others. Can you please help me?
 
What resonance structures were you able to draw for the others?

They're all wrong, coz I was only able to draw chains and not branches. But still, I believe they have resonance structures. But option 3, I'm not able to do anything.

I don't understand what this means. What are the structures you drew?

Sorry sir, I don't know how to explain further. I'm not able to insert the picture of what I've drawn, otherwise I could've shown you at what conclusion I've arrived at. Please sir, it's urgent and important. I shall compare your answer with what I've understood or got and learn it.

This is not how we do things here. We can help get to the solution, but we will not give you the answer.

This thread belongs in the homework section of PF. Please post there with a proper attempt at a solution.
