Thanks mam

1). Out of Benzene ( Aromatic ) and Cyclohexane ( Non-Aromatic) , which is more stable ??? 2). Why anti-aromatic compounds are unstable even being conjugated?? 3) In last section of video, you kept tropylium carbocation behind cyclopropenyl carbocation in stability order, Is there any standard reference supporting this(other than your CSIR notes) ??

[@Misschemistry]

(1). Cyclohexane is more because there isn't any ring strain , all bond angle are 109.5 degree , as per sp3 hybridisation of carbon, but benzene have pi cloud there is a great electron density above and below the plan of the ring so , is reactive. 2). Instability of antiaromatic comes from paramagnetic ring current. Stability of aromatic comes from diamagnrtic ring current. It can be explained by frost circle. In (4n+2) aromatic compound doesn't have unpaired electron so these are diamagnetic in nature and posses diamagnetic ring current. Antiaromatic compound posses two unpaired electron so these are paramagnetic in nature. Theses two unpaired electron may lies bonding , non bonding , or antibonding. (3). Aromatic compound has the tendency to increase the delocalisation of pi electrons in itself for these purpose they moves towards planarity. So smaller ring moves towards planarity easily while larger rings moves towards planarity hardly that means smaller ring posses more aromatic character then larger rings. Hope this helps Thank you

@@Misschemistry Regarding to the third point, it is absolutely wrong to say that smaller rings have better aromatic character ( you must have been taught by typical delhi kind of CSIR NET faculties, they all have same generalized notes, circulating all over northern India, sadly many of concepts they serve the students, are grossly wrong). While smaller rings have closer p orbitals so one can expect better delocalisation, but at the same time they have significant angle strain as compared to larger rings. So overall stability is determined by the dominant factor. Experimentally, it is the hydride ion affinity ( among others are the rate of solvolysis and half life period), which is used to compare the stabilities of carbocations. Lesser is the HIA(Hydride Ion Affinity), more stable is the carbocation. HIA for seven membered tropylium carbocation (C7H7+) is 200 Kcal/mol whereas for three membered Cyclopropenium carbocation (C3H3+) is 223 Kcal/mol. So this data can be used for the generalization that Smaller rings have lesser aromatic character than the larger rings( For the rings containing three to eight members, to be precise). Thanks. P.S. Don't take it as I am trying to undermine what you teach, its just for sake of positive discussion. Thanks. Further discussion is anticipated.

Thank u ma'am

[@radheshyam-oo8hg]

mam mesomeric effect aur resonance effect Kya same phenomenon hota hai goc me

[@Misschemistry]

The main difference between resonance and mesomeric effect is that Resonance occur due to the interaction between loan pairs and bond pairs where mesomeric effect occur due to the presence of substituent groups or functional groups .

[@radheshyam-oo8hg]

but mam resonance bhi substituent ke lone pair se hota hai

Ar/aa/na hamesha stability order kyo hota h mam

Bataiye na mam

[@Misschemistry]

Dekho agar hme kisi bhi chiz ko solve krna pde . To uska ik formula hota h na . Or vo formula app yad krte ho right Vase hi agar apko stability niklni h . To ye yad krna padega ki stability order Aromatic / aa / na. Yahi chlta h

Aromaticity hone ke liye conjugation bhi dekhna jaruri hai only odd or even π bond dekhne se thodi n jaruri hai agar conjugation nhi hai to wo non aromatic honga

[@Misschemistry]

Yes sabhi conditions dekhni h . Jo example mene krvai h usme sab mai conjugation present h . Agar conjugation present h tabhi trick apply hogi .

[@Misschemistry]

Sari conditions btane ke bad mene trick btai h. Mtlab apko phle conditions dekhni h . Then trick apply

[@Misschemistry]

An allylic carbon is a carbon atom bonded to a carbon atom that in turn is doubly bonded to another carbon atom.
