Resonance Structures
This organic chemistry video tutorial provides a basic introduction into drawing resonance structures. It explains how to identify the major resonance contributor as well as the minor resonance contributor based on stability. Here are a few key concepts to keep in mind: Negative charges are stabilized by electronegative atoms. Neutral resonance structures are more stable than those with separation of charges. Tertiary carbocations are more stable than secondary and primary carbocations due to the inductive effect and hyperconjugation. Positive charges on carbon atoms are not stable due to the octet rule.

Due to breaking of aromaticity, the “primary” cationic structure is the major resonance contributor for the benzylic cation
Why isn’t the bottom left at 6:05 tertiary?
Thank you!!!
King boss tumas Tutor🙏🙏🙏
2:47 why is the positive charge there? isn't there 4 bonds at that corner so the formal charge is 0? I'm assuming hydrogen is there
İsn't third one 3° carbin in 5.56 example?
why couldn't the middle carbon gain a lone pair as part of resonance on the first molecule?
Wait whats the difference between the primary, secondary, and tertiary?

@9:37 oxygen is more electron neg than sulfur, so wouldn't the major contributor be the structure where the neg charge is on the oxygen, not sulfur...?

Electronegativity is the tendency to attract shared pair of electrons to itself. Oxygen is an acceptor, not a contributor.

Sulphur has larges size
@winterflower4530
3 жыл бұрын
I did a little more research behind this cuz I was thinking the same thing- it turns out that even though oxygen is more electronegative than sulfur, sulfur is much larger due to periodic trends. This large size allows it to spread out the negative charge better making it more STABLE. I think the key is to think which atom is more stable with the negative charge, not which atom is more likely to have the negative charge. In other words, when comparing elements in the SAME COLUMN (like O and S) look at its ability to stabilize the charge rather than just electronegativity - the greater the size of the atom, the more stable it will be with the charge. On the other hand, when looking at elements in the SAME ROW (ex. C vs O) you can just use your electronegativity trends cuz elements in the same row are roughly the same size- hope this helped :)

@joharahk4849
2 жыл бұрын
The positive charges are jumping because as shown in the first example, the pi bond is becoming a single bond, basically “losing” a bond, giving it a positive charge since they’re essentially opposite (when a bond is lost it’s positive, when a bond is gained it’s negative). Hope i explained that accurately I'm learning too :)
