thank you so much, your videos help me heaps to understand the organic chemistry... i always wondered why there is no charge on nitrogen when it is in an nitro, then i found the answer in your video that the no2 is net-neutral because of presence of both positive and negative charges

@bonbonpony 2 года назад

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 2 года назад

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/

@Leah4sci Год назад

@morgie1347 Год назад

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 Год назад

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.

I don't follow. Benzene is not a bicyclo molecule

How many resonance forms are possible (which delocalize, or move the charge): Ph-CH2+ (Ph is phenol)?

@raisomuqtar3441 3 года назад

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

@Leah4sci 3 года назад

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.

@wehtam 3 года назад

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

@Leah4sci 3 года назад

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.

@ruqayasuadad3105 7 лет назад

my lovely prof

@Leah4sci 7 лет назад

Thank you!

@rrrffaaaash3649 4 года назад

why we convert the green bond to lone pair?

@Leah4sci 3 года назад

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.

Amana Prateek oxygen is more electronegative than nitrogen

These are the formal charges and have to do with how many electrons each atom has around it. I teach formal charges in detail here: leah4sci.com/formal-charge-formula-shortcut-for-organic-compounds-video/
