Which Among These Species Does Not Exhibit Resonance?

AI Thread Summary
The discussion centers on identifying which of four chemical species does not exhibit resonance. The participants debate the options, with one individual suggesting that 1,4-Cyclohexadiene is the correct answer, as they could not draw resonance structures for it. Others express confusion and seek clarification on the resonance structures of the other compounds. There is a call for more detailed explanations and attempts at drawing structures, but the conversation is ultimately redirected to proper forum etiquette, emphasizing the need for participants to post in the homework section with their own attempts at solutions. The thread concludes with a closure, indicating a lack of adherence to forum guidelines.

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.
