All the team members are gems ,efficient teachers jaisa jyoti mam padhate hain similar Hai sbki teaching....First channel in higher chemistry allover country to have this type of initiative. You are the boss lady, porsche with no breaks.... an inspiration to me Thank you mam!!!💖
Elegant way of teaching! Each and every Concept is easily understandable.
Thank u mam for a great initiative... Explanation of every topic is awesome... Jitni bhi videos aayi hain bhut achi hain... Exams oriented hain...
Excellent revised explaination, i understood everything in this lecture
Extraordinary knowledge...One of the best goc lecture I have ever seen.
All the videos are highly exam oriented,,...this videos are helping a lot for revision....all time copy se parna acha nhi lag raha...to aise acha lag raha parneme....thankyou mam and sir
Sir 💎 i am very weak in organic !! .... Mujhe bhi smjh aaraha h ... Iska mtlb you are an awesome teacher ... Thankyou so much sir 💎
I agree with you didi
19:08 very Good explanation but plz do correct me . Why Nucleophile goes towards the pie orbital rather than antibonding of C--Br bond ??? The pie orbital having and electron density as compare to c--Br bond .. is there any clash or repulsion between π bond of carbon and Nucleophile ????
The best way to teach organic chemistry. Thank you so much sir for such a easy and awesome explanation
Very nice explination.All basic concepts clear. Thank you sir🙏
Wa sir g
Etny basic cosapt s smjhaya h aapny ke chemistry k hr studant ko samajh aagya hoga
Awesome lecture. Thanku Jyoti ma'am nd the entire j chemistry team
Your basic consapt is you Introductin on Teaching field
Effortable and easily understandable method of teaching 👏
Inhone to vo smjhaya jo shayd hi aajtk kisine thik se you tube pr smjhaya hoga 👍👍👍👍 bs ek doubt hai ki starting k 3rd que. Me jo double bond h vo π hai ya π* kese pta chla?
π bond ko break karne k liye π* me electrons jate hai...jo jo π bond break hua uske π* me electron gaye hai...
Uv visible spectro ka mam ka lecture dekh lo usme mam ne basic humo lomo samjhaya h waha se bahut sara daubt clear ho jayega
Thank you so much team j chemistry for this very helpful initiative.
Last example or aromaticity is aromatic or antiaromatic... Please explain..
sorry for correction Sir but ek jgh apka explaintion me chiz smjh ni aai ti jaha pe apne oxgyen gruop {Se S O}donar ability batatye te wha par to hm size se decide karnge donar ability ko na ki electronegavitity se beoz wah pe size factor work karta hai kyuki down the group to size decide karte hai
Top class....... Good teacher..
Voice is too nice for understanding
Thank u sir..
Very nice explaination. 👌 It's easy to understand.
nice content with nice explaination sir.... its a kind a short quick revision
Thanhu mam and sir for making this videobahut achha padhye ha sir
Sir, aapne at 24:30 pr, anomeric effect me question 2 me bataya ki Hb ka antibonding aur N ka nonbonding interact karke partial double bond character show krega toh C-Hb bond break ho jayega (due to bond length increase) but sir aapne Anomeric effect ke 1st wale question me bataya tha ki C-X bond break nhi hoga, eska matlab kya? Please confirm sir🙏🙏
Excellent explanation sir ✌🔥... Thank you so much
Very nice explanation ❤️
Very excellent explanations
..thanks to all j chemistry team
Thank you so much mam 🙏🙏🙏
Nice way of teaching 👏
Thanku so much sir 🙏 superb concepts
Nice sir mam bhot accha padhte hai app aise normal logo ko bolo pdhne ke liye
Nyc explaination
Sr aage bhi organic mi baki chapter se kese relate kr skte h kisi topic ko uska bhi idea dete rhiyega👍👍👍
Thank you so much sir,,god bless you
Great teaching🎯
Thank you so much ma'am and Sir 🌻😊🤍🙏
Fabulously explained 🙏
speechless !! 👍
Mam ye aapka hi jadu h ki u tube kholte hi isliye h ki crash course aa gya hoga ..
Thank you mam nice video 👍
👌👌👌👌
Very understanding video thnku sir
Best session 👍
Thank you so much sir🙏🥰
Are All Halogens stable at axial position sir? Please tell me
Yes all halogens show anomeric effect.i.e they are at axial position on anomeric carbon but not with same rate.The order is I>Br>Cl>F...There are two reasons for that
1) on electron transfer from oxygen to C-X sigma * There is development of negative charge around halogens. The Iodine, due to its large size have more dispersed d orbital which stabilize this negative charge.so order is I>Br>Cl>I
2 )in this case LUMO is C-X sigma * which receive electrons form oxygen,...C-I bond have its LUMO at lower energy as compared with all C-X bonds .so lower LUMO accepts more electron .

Excellent
very very helpful video !!
Mam vedio quality bht low h..uski vjh se kuch bhi clear nhi dekh rhh h
Thank you 🙏
Hello mam why not teach in English ,why hindi only teaching??? What reason mam ,u
Very nice session and very informative
Really sir you are very good
So.. last example kya hoga aromatic yea antiaromatic?
Pata nhi kyun
but aap ...kota factory ke meena jaise lag rahe
.....
Happy learning guys...me to puraa
Thank you j chemistry team
Ma'am iit jam chemistry ke liye bhi aisa initiative li jiye na ma'am bohot e beneficial hoga hum logo ke liye pls 🙏🙏🙏🙏🙏🙏🙏🙏 ma'am...
This lecture was very very helpful
Exam ki date a gyi hai kya ...? Mam
Really helpful 👍
Sir ne mst pdhaya ek dm 👌
Electrochemistry
Crash course me sare chapters hai....electrochem bhi ayega....u can check the first videos description for full schedule of this crashcourse
Sir / mam pls start for Jee and Neet chemistry
Very nice session sir, 🙏🎉🥳🤩🥳
Excellent 👌👌👌👌
Confused teaching,,,,🧐😣
Nice explanation sir
Sir aap bahut mast samjhaate hai
He says exactly opppsite to what he writedS at times... Please thoda speed kam kijiy aur confusion bhi
Literally, sometimes he gets nervous and avoids explanation after uttering some wrong facts. Specially, ek jagah sir bole O ki EN kam h S and Se se 😂, its ok though SIR sudhar lenge ye problems time ke sath sath
Mam is it for iit jam also?
you explain very nice sir
Ortho effect?
Mam mujhe organic chemistry very nice lgti h
😂😂🤣🤣🤣
Sir please give name of reference book
सर लय भारी 👌 सलाम तुम्हाला 😊 ग्रेट thank u.
Sir acetylene (Ethyne ) sp carbon and benzoic acid yachyat comparison kele tr konachi acidity jast asel.
@@rahulbhadane7094 benzoic acid will be more acidic .it's pka is 4.20 and ethyne will be less acidic with pka around 25 . In benzoic acid the conjugate base is more stable than in acetylene
May I get j chemistry complete course
sir cl hydrogen bonding nhi krti h .........
-Cl doesn't make strong hydrogen bonding, but it makes weak one...when Hydrogen bonded with electronegative Oxyegn atom will in vicinity with -Cl atom....this weak hydrogen bonding only slightly changes acidity, hence pKa values are only slightly different.

Nice voice nice teaching.
Missing Jyoti mam 😢
Nice 👏👏
👌👍
Sir khud hin bahut hin confuse hai
In the hyperconjugation , C-SiMe3 or C-H which will be fast ?
Weaker bond takes part more in hyperconjugation .Since C-Si bond is weaker than C-H bond,hyperconjugation will be faster in case of C-Si bond.
Reference: Bond dissociation energy of C-Si bond is 318 kJ/mol and that of C-H bond is 431 kJ/mol
Agr yh paid hota to mai join krta ... Thanks for free
Beautiful session sir 💕💝💝very nice explanation 💖🎊🎊🎁🎁🎇
Sir please have trick for EDG or EWG keliye please sir don't ignore this msg....🙏🙏🙏🙏💓💓💓it humble request ....🙏🙏🙏🙏
So good yar
Mam NGP padaye
Thanks alot Sir .🌸💐you make organic so easy to understand..clearity in explanation is superb 🌼.First time i found this type of video which make org understandable.
Org pdhne ka mn kr rha h ab..vrna leave kr dety thy..# MuchAppreciable work .
2nd view 🥰🥰🥰
