    So which of these structures is more stable and which one is less? How does the number of possible resonant structures influence the stability? More structures is better?

    • @Leah4sci
      @Leah4sci  2 роки тому +1

      My goal in this video wasn't to compare the stabilities of these molecules. But yes, the more resonance structures that a compound has, the more stable we consider the molecule to be. For more on resonance, see my series at leah4sci.com/resonance-structures-in-organic-chemistry/

    for that final resonance structure of the molecule with NO2, does double bond have to be put back onto the same oxygen? Or could you choose to put the double bond on the other oxygen?

    • @Leah4sci
      @Leah4sci  2 роки тому

      You could choose to put it on the other oxygen! They are equivalent atoms, so either way works. Just make sure you don't double bond them both at the same time because that would violate the octet rule for nitrogen.

    so how many resonance structures does benzene have? should we count the internal resonance structures?

    • @Leah4sci
      @Leah4sci  3 роки тому

      I’ve drawn out all possible resonance structures for benzene at 5:30 in the video. I don’t quite know what you mean by ‘internal resonance structures’. If you’re speaking of the ones in which there is a separation of charge, they do technically count as resonance structures for benzene, even though they are only minor contributors.

    Is the reason touluen cant participate in resonans because the carbon cant donate nor receive electrons or because it is sp^3?

    • @Leah4sci
      @Leah4sci  3 роки тому

      It’s not that toluene doesn’t have resonance. It still does in its ring structure. The idea expressed in this video (6:12) is that the methyl substituent on toluene can’t participate in the resonance because it doesn’t have a great source of electrons. It has neither lone pairs nor pi bonds. It also can’t receive electrons because then the octet rule would be violated for carbon.

    why we convert the green bond to lone pair?

    • @Leah4sci
      @Leah4sci  3 роки тому

      I don’t know which exact example you’re referring to, but the idea is that a pi bond is a source of electrons which are delocalized. These electrons can move around the molecule to form various resonance structures. They can rest on an atom as a lone pair or form new pi bonds in other locations.
