Ma'am ap to bhut bari inspiration ban gaye ho ..sach me ....this is the fisrt vedeo of j chemistry❤️...jis institute k aj mai ek hissa hu ....not believable.
Mam aap. Net jrf ke questions baad m. Kara ke bht acha karte ho kuki sath m hum bhi solve kar dete h.. Or aap. Phadate itna acha ho ki humse easily solve ho jata h uske liye thanks mam
@15:28 The example that you taught is not a fulvalene system. It's a fulvene system and in this compound the polarisation of the exocyclic double bond occurs in the direction of the ring and hence fulvene system attains aroamtic character. This anion is also known as cyclopentadienyl anion and is aromatic in nature. The example you taught in @16:37 is a fulvalene system i.e., triafulvalene. I hope I am not wrong!
I have been following your channel for a couple of months. you have become "THALAIVA" now. This is your first video naa soooo cute Jyothi, I felt very happy seeing you transforming to an amazing teacher. what a transformation...! This shows your determination and passion. love you dear.....
I don't know Hindi. But your present videos, expation very excellent and easily understood. That's y I came to this video. But I got thet point how you improve your online classes skill. Very innovative and fast mentor. Thank you and very nice to meet you mam
Jyoti ma'am I'm a BSc student but I am planning to sit for GATE after my graduation . Your videos motivate me to do good and the concepts I get , makes it easier for me to summarise the topics which helps me in revision as well . I am very grateful for everything you are doing for the students ❤️. Best wishes ,🌸
This is the best aromaticity lecture I had ever seen during my all studies, thanks for this one. You will grow much more if you give content like this.
in first example, in seven membered ring having a positive charge is aromatic but the same example with negative charge is non aromatic. i didnt understand this.
Hello Madam The structures r not clearly visible due to reflection of light on the board...no doubt u hv given up cent percent it will be so kind of u if u repeat the same lecture in a clear background..u r one of my best n fav teachers I watch ur all topics whatever I know about spectroscopy its only bz of us sessions...thank you so much for ur guidance....
Madam aapne kaha ki oxygen k dono lone pair p orbital m h ...... Lakin yaha to oxygen sp3 dikh raha h.,.., to lone pair to sp3 orbital m hona chahiye jo ki sp2 carbon k P- -orbital k parallel nhi hoga Aur resonance stop ho jayega...., eska dusra example aap phenol b le sakate ho madam ji....... Pls madam clear my doubt, pls reply me..... .... Ok thanks
Mam I have a doubt as 4n+2 will give even number, if huckels rule follow that is called aromatic na, according to ur say if odd numbers of pie electrons in aromatic, which is right give clarity mam
Madam, in last question 2nd one is seven membered compound.Why is it not non aromatic since anti aromatic compounds that have more than 6 members convert itself to non aromatic by losing planarity.PLEASE EXPLAIN.
Mam while solving the example that includes Lewis acid , you have shown both positive charges on adjacent carbon atoms and also in next example that includes sodium , both negative charges are on adjacent carbon atoms ... this is unstable .. can you please clarify this part. Very helpful videos thankyou :)
Thank eu so very much ma'am,,its mah first day dt I hv joined ur chnl n jst now I hv gne though diz aromaticity part,,it's really very helpful fr me..m frm Assam n m in Bsc 4th sem now,, m preparing fr IITJAM.I don't know how to thank eu ma'am,,👍
Very nice and helpful video. Just tell me when cyclooctatetraene gets 2e, does it become planer from non planer?becoz cyclooctatetraene is non planer. If it becomes planer then only it will become aromatic.
Fulvalene mein bond shift nai ho skta bcoz there's no electronegativity difference but uske baad wale example mein @16.38 aap bond kyu shift kr rhe ho? Please clear..
In case of fulvalene if we break the bond , we'll for sure get one aromatic system which is a five membered ring ...but along with this ...we'll get CH2^+ On the other hand we're breaking the bond in next example and getting two aromatic rings i.e. overall aromatic system ...so here charge separation leads to a stable system In fulvalene aromatic ring + carbocation is formed which is an unstable intermediate
hey mam last question in this video i have a doubt...a mono cyclic ring with 7 or more than 7 atoms can not be anti aromatic because of highly unstable than i think B will be homoaromatic
Mam in first example when you add two pottasium then two pair of electron came.But in the last example (annulene)you add only one pair of electron.Please explain
In first example ...I'm breaking a bond first ...such that one of the C gets negative charge and other gets positive charge ...and then ...2K will give 2 electrons to the C which got positive charge ...2K will give 2e only....the other - charge was due to bond breaking Similar is the case with last example .. You can do it similarly... Break any of the bond and ..then add 2e to the carbon which is carrying + charge ...
Even though sound quality is bad i am very happy bcz this video cover all the syllabus of aromaticity
Than you mam
Ma'am ap to bhut bari inspiration ban gaye ho ..sach me ....this is the fisrt vedeo of j chemistry❤️...jis institute k aj mai ek hissa hu ....not believable.

And the tropylium anion? Isnt it antiaromatic?
are you sure what you said is true??
Your sound may not be loud ...but your confidence is the best mam

Outstanding madam
Your understanding is excellence
My all doubts are clear from Aromaticity
Thq very much madam
Extraordinary,,,,, knowledge,,,, j chemistry
madam pls reload it again with good sound quality

Amazing video, so much helpful, thank you so much mam 🙏🙏🙏🙏🙏🙏
Mam aap sachi bht acha phadate ho🙏
Thanks a lot mam...
Sachi mein thank you :)
Thanks mam everyone can understand the way of ur teaching
This is the best aromaticity lecture I had ever seen during my all studies, thanks for this one. You will grow much more if you give content like this.
Nice video, my concept is clear after 2 years. Thanks mam.🙏
Mam you are my best teacher
Thanku very much mam
This is amazing video
Mam you have come across a long way. I personally connect with you too much as a student. Thank you maam
mam aap bahut he easy way Sai samjate ho ab ache Sai samaj aa jata h aap har topic jo net point of view Sai h mam in sbka video upload kre
Really appreciable mam thankiuuu so much
Super video and very helpful for me 💞
Very nice explanation. Love you Ma'am.
Nice looking mam ap bhot unique padhati ho❤️❤️❤️
Sound quality is very low
This was the first video,now problem has been resolved :)
@@JChemistry mam please make this video again in green board
@@JChemistry please make this video again
@@JChemistry no mam problem is not resolved ....🙄🙄
But education quality is awesome
in first example, in seven membered ring having a positive charge is aromatic but the same example with negative charge is non aromatic. i didnt understand this.
@@shivamchaubey4896 r u sure about it? In jerry march's book it is said that the compound is antiaromatic
Mam this video phir se record kijey na ?? Sound quality is not good. That's a big problem
Best lecture on TH-cam about aromatic compounds 👍
Tq mam your explaining well
Most useful vedio
Mam the board is not clr..mujhe to kuchj dikh hi nhi rha
You done wonderful job mam
Mam.. wo 2Na wala jo example hai.. that final product is non planar na. So it should not be aromatic... Plz clear this to me.
Sound quality check kr lena chahiye ma'am

Improve sound loudness and vedeo picture quality, use dark coloured marker only , remaining material is good , keep it up
First improve your english.
Di sp ,sp2 and sp3 hybridization kaise identify kre plz batana.
Very informative class thanks mam..
Madam, in last question 2nd one is seven membered compound.Why is it not non aromatic since anti aromatic compounds that have more than 6 members convert itself to non aromatic by losing planarity.PLEASE EXPLAIN.
Who's here after ma'ms new qna video after 0.1million subscribers??
Comprehensive 👍👍 that's the only word would justify this video!!
What is order of decreasing aromaticity in benzene, thiopene, pyrol, furan?
Very nice explanation mam 👍
Mam fulrene kaise non aromatic hai
No picture and sound clarity mam. Please reload starting videos. The other updated your videos very excellent.
Carbon with negative charge is sp3,then how can we consider it for conjugation?,the carbon should be sp2 ,right?
If possible provide us SET Maharashtra Chemistry important topics concepts videos.
Thank you 😊
The e.g. after fulvalene also has no electronegativity difference.....then why did the bond got polarised?
Is there complete delocalisation of pi electrons in the five menberered cyclic boron compound with two pi electrons. How it can be anti aromatic
Mam last question me 8 membered ring h is this planar???
Ma'am pehle aapne bola tha k 7 membered ring non planar hoti h lekin baad mei 32:18 paar aap bol re ho k aromatic h ye kaise?
Mam fulvene non aromatic kyu h...non ...sp3 kisi bhi ring pe nhi h..
thanks Ma'am

mam yu are really great teacher in the field of chemistry
Thanks you mam but visibility quality is. not good
Jordar rank apki nice
In case of acidity order in PYQ benzene ring attached with anhydride like system will get somewhat more stability than bnz ring not attached?
are all types taught in all colleges?
5 types?
Mam please video ki sound quality thik karde
Can't see the matter written in whiteboard
Thank you madam...
Hi . M from Pakistan . How can i get pdf assignment?? Thanks in advance
Very nice and helpful video. Just tell me when cyclooctatetraene gets 2e, does it become planer from non planer?becoz cyclooctatetraene is non planer. If it becomes planer then only it will become aromatic.
Is this help ful for a jee aspirants
Mam how we get same molecule after passing C2 axis in azulene
Fulvalene mein bond shift nai ho skta bcoz there's no electronegativity difference but uske baad wale example mein @16.38 aap bond kyu shift kr rhe ho? Please clear..

Ma'am please tell which subjects from clayden book should be read for NET?
Such an amazing class!
Thank yuo mam for these kind of help
hey mam last question in this video i have a doubt...a mono cyclic ring with 7 or more than 7 atoms can not be anti aromatic because of highly unstable than i think B will be homoaromatic
Hello mem pls help me chloroquine na IR study ,NMR ane mass kae rite sodhvana
Mam in first example when you add two pottasium then two pair of electron came.But in the last example (annulene)you add only one pair of electron.Please explain
2K will give 2e- i.e. a pair of electrons...please tell me the time in the video where you've confusion
38:23
In first example ...I'm breaking a bond first ...such that one of the C gets negative charge and other gets positive charge ...and then ...2K will give 2 electrons to the C which got positive charge ...2K will give 2e only....the other - charge was due to bond breaking
Similar is the case with last example ..
You can do it similarly... Break any of the bond and ..then add 2e to the carbon which is carrying + charge ...
Low sound 🙏
Mam itni low sound me kuch clear nhi ho rha..
Amazing video
Good job mam
God bless u
Mam kya aap recently 2-3 dino me electron diffraction pda skti h kyonki semester hone vala h
Mam sound was low
Very useful for TN poly trb
Madam, there is a time lag between audio & video...which creates problem for the students...
Mam Plz make a clear video on aromaticity
Can you do this video once again. Sound is not clear. We can't follow Up
Can you do this video again?
Mam your lecture very nice.. But sound quality low. In this lecture i have screen shot so my kind requst move to out of the bord..
sister very nice video, keep uploading videos for us.
Why antiaromatic compounds are less stable as compared to aromatic compound
Thank you mam
Isn't tropylium anion antiaromatic? In jerry march's book it is said that the compound is antiaromatic
Also in question 3 (net Dec 2012) , is compound A an aromatic? As it gets 2 pi electrons(= 1 pi bond) on methylene group ?
Mam is back. Hurray. Thank God 😄👏👏👏
At 15.22 around, it's fulvene not fulvalene
