Carbanion stability order Trick | Organic Chemistry | IIT JEE & NEET | Vineet Khatri Sir | ATP STAR

[@vikashtiwari2175]

Sir after that di keto question in next question there was OCH3 but it shows -I effect therefore order should be a>c>b

[@raghavchawla3134]

[@RocKShadowYT]

6:15 actually at this point 1st structure is anti-aromatic as it has 4nπ electrons used in π bonds so according to me it must be least stable

[@BareGrylls-vh1xr]

Wrong. Brother. How I identify aromaticity is by counting the no. of π bonds and then adding the l.p.(1 l.p. = 1 π bond) which is equivalent to 3 π bonds (total). Since odd no. of π bonds suggest aromaticity and even no. of π bonds suggest anti aromaticity. Therefore the 1st compound is aromantic

[@nafisaparveen9759]

Can anyone pls solve my doubt... according to goc CF3- is more stable than CCl3- due to Inductive effect, while according to back bonding CCl3- is more stable than CF3- so which is correct??

[@nafisaparveen9759]

Please solve my doubt!

[@tirthpatidar4927]

You should check resonance over inductive effect because it gives more stability to compound generally, now in this case resonance is because of +ve charge on carbon and resonance is more effective in CF3 as compared to CCl3 because of difference in period or u can say there is bonding of 2p and 3p in CCl3 and 2p -2p in CF3 so resonance in CF3 is more effective which deintensifies +ve charge and gives stability to compound .....You can use inductive effect but in some ques like this u have to take care about period of atoms and there bonding orbitals .....

[@subashkalra6124]

In ccl3, there is presence of d orbit which delocalises the electron and the negative charge of the ccl3 goes into the resonance. Ccl3 is more stable.

[@apoorvsakshi6090]

Sir how can I compare stability in multiple rings alkene??

[@monikhab3527]

sir,in 4 th example...the middle compound is +IE(ch3) group,,then how it is more stable than the one with och3??

[@hrithikdwivedi6179]

sir last example mein electron density oxygen par badh jaayegi. Isse toh wo zyada unstable ho jaayega, already F toh -I effect show karega. Phir 2nd wala structure zyada stable kaise? Please explain.

[@vidushigupta5697]

Hustler Dwivedi hmmm F - I show karega iska mtlb wo electron Apne taraf khiche ga,jisse oxygen pr electron density km ho jaega,or wo jyada stable hoga... Kia ye explanation kuch kaam aaya??

[@guptashubham28]

Does Hyperconjugation effect the stability of Carbanion..?? Someone please answer

No hyperconjugation in carbanion

Sir... I have a query.... In the benzyl carbanion carrying methoxy group.... It would show -I effect... Due to which it should have got stabled.... So the order of stability should have been a>c>b??😶

[@omparikh4426]

yes same doubt

[@deehanchowdhury1230]

Methyle group will show electro+ve nature by donating electron , is it because it has sp3 hybrd? if so then carbanion is also sp3 hybridized so why should it accept electrons from the three methyle grps?

[@whitedevil8874]

No it doesn't happen carbanion's stability decreases when it is surrounded by 3 methyl grps

[@saurabhmodh1899]

Nice explanation 😊

[@qwertlasts]

[@adityaedara3499]

why is phenyl carbocation unstable while phenyl carbanion stable? shouldn't phenyl carbanion become anti-aromatic?

[@vikashbaraik9739]

[@nikhilgautam007]

Sir antiaromatic is more stable than nonaromatic in last example.Please reply.

[@shikhaagarwal922]

yes cause antiaromatic is least stable

[@vineetsood1346]

in the starting i am not able to understand the giving and taking of electrons between oh- and h?

[@jasheelaaziz4668]

Is it just opps to carboctions xcpt ring

[@arthsojitra2226]

sir a 6:20 how did u compare stability of b and c????... both are indeed anti aromatic .....

[@alokpatel9020]

Due to hyperconjugation

[@chemlover1008]

B is non aromatic

[@Kajalbiophilic]

B complete resonance show nhi kr rha islie vo na hi aromatic h aur n hi anti aromatic........

[@whitedevil8874]

B is non aromatic due to the absence of complete conjugation

sir I think in the last e.g. both B &C compound should be anti aromatic. than how u made this following order A>B>C

[@krishnaprasadch2081]

no ,though option b has 4n electrons it doesn't have continous conjugation so it turns into non aromatic

sir you are really amazing

[@manishjoshi2055]

What if we have constant in between like 1methyl benezene .such constant are so much problematic bz thier position are like impossibke to determine

[@shinning_starr4007]

Thank you sir 😁

[@DC01]

Sir in +I it is sp3 carbon which donates to sp2 carbon because of electronegativity difference , but here the carbanion is also sp3 hybridised so why should 3 degree be less stable than 2 degree because no +I should be there ??

[@atpstarkota]

Real reason Steric replusion se explain hota hai.

[@DC01]

ATP STAR-JEE & NEET,KOTA why is the migratory aptitude more for rings with ERG , like in Hoffman bromamide degradation the rate is higher if there is an ERG on the ring than with an EWG whereas the negative charge should ideally be more stabilised by and EWG EWG-Electron withdrawing group ERG-Electron releasing group

[@puspalatamartha5272]

[@shikhaagarwal922]

AK Singh I dont think that there would be any resonance in either of the two cause there is no double bond and double bond is the soul of resonance

[@arghya.7098]

5:09 Why in +I effect of methyl group dominates over the repulsing factor by the lone pair of Oxygen. Please anyone reply properly.

[@persephone1571]

repulsion causes the most instability

[@devaki9483]

Because repulsion leads to unstability

[@whitedevil8874]

Ch3 provides en by +i and hc but och3 gives by +R but so as to stabilize the -ve charge en must be withdrawn and not to be given

sir in the 6:17 isn't the pentane ring also anti aromatic in nature? so the stability of cycle pentane anion and cyclo propyl anion is the same right?

[@manaspratimnath2250]

abhishek shankar 6.17 ---- a is aromatic..b is non aromatic as two Carbon atom in the compound are sp3 hybridised..and c is anti aromatic..non aromatic is more stable than anti

[@kalbeabbasgandhi738]

Conjugation breaks in whole pentane ring so it's non armoatic

[@vishnuep6582]

at 3:40 ; won't the cross conjugation make it unstable ?

we can use the concept of cross conjugation when no. of pi bonds are equal in all the carbanions we are comparing

[@karansinghyadav3358]

Hello sir your new subscriber

[@saurabhpandey3289]

Sir at 3:19 that -charge on a compound will make it anti aromatic after getting involved into resonance so how it can be most stable

[@saurabhpandey3289]

Means on (a) compound*

[@kiratiwari3428]

No it will not be anti aromatic because conjugation is not continuous and you also have to check whether it is cyclic, have 4n+2 pick electrons, is planar and it must be associated with a conjugated ring

[@kiratiwari3428]

It is most stable because of delocalization of electrons around the compound which increases it's stability and because it is happening twice it is most stable out of the three

[@dummydummy0]

At 4:57 how does NO2 show -M effect ??
