Nice efforts ma'am..... thank you for sharing these wonderful knowledge and concepts wisely .... pahle hame Delhi jana pada ye sab sikhne (2018 me hi jab aap bhi shayad vahi the) par aj ghar bethe ham apki vajah se revision kar pa rahe he.... dhanyawad आभार आपका 🙏🙏💐
Maam...oh my goodness....sometimes u must amaze urself..superb..sensational...mozza as gaya..good morning...have a nice day..love and respect from Assam
Mam m soch rhi kaash mujhe phle apke chnnl ka pta chl jaata to m kbhi coaching na leti...apse hi online coaching leti...organic mujhe blkl nhi aati lkin aapki video mujhe confident bnati h....god bless u🙏🏻u r amazing...nd more more more intellingent❤️😘 #JChemistry
in the example mentioned in time 21.13, we are considering endo product to be the major product. Please tell me the reason behind neglecting the steric hindrance between the COOMe group and the Me group as both are above the plane.
in the endo product there is primary as well as secondary interaction which makes the TS more stable, if TS is not stable then how will the product be stable.IN SHORT stability of TS is more imp and then according to the TS the product will be formed
Slight Correction at 5:08 - Ma'am first you stated that endo product is less stable in compared to exo because it is kinetic as its T.S is less stable and in the next sentence you said that T.S of endo is more stable. I'm a bit confused. May be it was slip of tongue. Please verify once.
The sigma bond which is being broken should also be counted as it is too participate in ring opening and forming the π bond.. Thus it is 4π system.. ✌️
Mam exam me organic ke questions me Bhut jada symbols use hote h like for acyl group( Ac) to question bhut tough lgta h... To ye problem kase solve ho secti h mam..
Mam in the first few minutes u said ki endo me transition state kam stable hogi badme at 8:50 u said endo me transition state jyada stable hogi to which statement is correct
First transition state is about k.c.p and t.c.p where she says that k.c.p transition state is more stable than t.c.p that's why endo product is more stable than exo becoz it's a k.c.p and later she also says that there are two interaction in endo product whereas there is one interaction in exo product that is also a reason behind the stability of endo product.... I hope you get your answer..
thank uh so much for ur kind gesture ....maam i find difficulty in retrosynthesis ...i find difficulty in making the rxn in reverse order give me some guidelines
Ma'am ek question hai , I hope you will answer . Last Wale example mai aapne 4n kese karwayi , kuki 4n means 4π e lekin aapne too ek hi π bond use liya hai means 2π e hi use aaye , too 4n wali reaction kese possible hui? Hope you'll answer 🙂
Mam last example main thora doubt hain aur apne Jo end of the reaction main kaha ki iski stereo kuch vi rakh lo farak nahi padega but Apne tu kaha tha left wale ko agar wedge main Rakha tu sob left wale ko wedge main hi rakhne padega....mam please explain it again 🥺🥺
Didi , apne Diels-Alder reaction ka Streo wala portion jo yaha karaya hai , woh Clayden se match nehin kar raha . Apne Diene par L hone par Above the plane likha hai ,par clayden pe Below the plane kiya gaya hai.
You're teaching knowledge and i can see you're but i can't understand the language you're using. Please in other updates do well to ue English that will be a big help for us English students. Thank you
Mam, good morning... .mam plz clear my doubts.....if I don't want do PhD after quallify net exam then what are other career opportunities .....could you suggest smthing.....
Mam ye 1or 2 numbering hum kiske according krenge. Koi rule h kya iska. Mam kbhi exam me hum apni mrzi se dale numbring or vo wrong ho mam plz give ur imp suggestions
Mam I hv qsn that agr endo Pdt kcp h to hum jante h ki kcp less stable hote h after some time and heat wo log TCP me convert ho jate h TCP more stable hote h then apne endo Pdt ko stable q bola Kuch books me endo Pdt less stable bol rhe h
Excuse me mam kya organic worth krti h ittna effort... Bcoz exam m organic k qus attempt krne m bhut problem hoti h.. And someone says me ki agr organic krni h to clayden carruthers pddni pdegi
It is very easy to understand left and right position .Double bond se jo aapki left side h vo left and jo right side h vo right or ji left side honge onki stereochemistry same hogi or Jo right side honge onki same hogi.
Mam 4.32 to time per aapane Jo concept batya hai wo galat hai because Jaha Endo product Hai woh ab Exo product Banega because interaction in between carbonyl group and 2 carbon location is not available
You made my pericyclic reaction easier then the professor did.
💝💝💝 From Bangladesh didi..
God Bless You.
Best channel to follow for csir Net preperation 👍
This series saved me in yesterday's exam! U r awesome mam🙏
Started following u 🙏🙏
Nice efforts ma'am..... thank you for sharing these wonderful knowledge and concepts wisely .... pahle hame Delhi jana pada ye sab sikhne (2018 me hi jab aap bhi shayad vahi the) par aj ghar bethe ham apki vajah se revision kar pa rahe he.... dhanyawad आभार आपका 🙏🙏💐
Aap ne bilkul "gulam sir" ke tarah samjhaya....good teaching.
Nice presentation mam.....now I am able to chase pericyclic reaction problems. thanks a lot.
Your class taught me how to be a better student.
Finally my confusion over exo and endo got cleared today.Tqsm maam.
Maam...oh my goodness....sometimes u must amaze urself..superb..sensational...mozza as gaya..good morning...have a nice day..love and respect from Assam

Jbrdst... Ye kon log h jo dislike diye h...
Exo endo concept aaj ja k clear huwa h😊
Ur work helps me a lot Maam...pericyclic reaction r no more difficult now..u r doing great Maam❣
Bahot achha lecture rehta hai aapki
Mam thank you so much now I'm very clear with exo and endo.....great teaching mam.
Mam jo diels alder wala endo exo bataya wo bhut hi acha tha
I am preparing for GPAT
Thank you 👍🏻👍🏻🙏🏻
कमाल है लोगो की ऐसे teacher ko भी dislike कर रखा है , और इससे ज्यादा dedication क्या हो सकता है... 🤔
👌🙏Extraordinary Explanation, TQ mam ,we follow your videoes

TS is more stable in endo
Thanks a lot ma'am... Explained very well:).
Amazing explaination! Thank you Ma'am ❤️
Thank u so much mam for easily problem solving tricks😊🙏❣
Thankeu ma'am yehe vedeo dekhne ka baad Mera doubt clear hogya
Bhot hi simplify kr Dia mam apne thnxx alot
Mam last question 4n system kese hua?..maybe 4n+2 hona chahiye!!
Thank you mam very effective trick that you have discussed.. now pericyclic reaction are very easy to understand... Thanks again God bless you
Mam i have one doubt ...the last example that u have given how is it 4n ...yeh toh 4n+2 hona chahiye tha ???
Now Satisfied for pericyclic reactions😃
JYOTI MAM LAST WALE EXAMPLE ME 4n system kese maana usko... wo 6n system bn ra ..? please explain ...
#big fan❤️🙏
The sigma bond which is being broken should also be counted as it is too participate in ring opening and forming the π bond.. Thus it is 4π system.. ✌️
Mam exam me organic ke questions me Bhut jada symbols use hote h like for acyl group( Ac) to question bhut tough lgta h... To ye problem kase solve ho secti h mam..
Very nice explanation mam with Crystal clear concepts 👍 thanks a lot

@@skataulhaque4376 thanks for the explanation 🙏
Thanks a lot ma'am
My all doubts are cleared. Today is my exam and it helped me alot❤
Thank you so much for continue the pericyclic series.. Tc
Ma'am pls can you explain that how last ques would be following 4n rule according to me it should be 4n+2.
Exactly that's my doubt also
Yaa
Same doubt herr
Same doubt mam
Hey ur teaching is good...got my concept clear...
thank uh so much for ur kind gesture ....maam i find difficulty in retrosynthesis ...i find difficulty in making the rxn in reverse order give me some guidelines
I faced the same problem ...but you can do one thing ...write the steps in correct order first and then reverse them
J Chemistry maam do uh think it is worth to do this topic for exam point of view ...can i skip this this topic ......
Ma'am last question mein 4 pi system Kahan hai? Jo humne trans ko CIS mein convert krdiya
السلام علیکم
Cis 2 butene + dienophile sy konsa product banye ga mam plz bta dena
Ma'am ek question hai , I hope you will answer .
Last Wale example mai aapne 4n kese karwayi , kuki 4n means 4π e lekin aapne too ek hi π bond use liya hai means 2π e hi use aaye , too 4n wali reaction kese possible hui?
Hope you'll answer 🙂
Hope
Its urgent mam plz respond
26:29 how it is 4π ?? 4n +2 nh h yh tu or 6π photo con or yhn heat h tu 6π heat per DISROTATORY ??
For preparation of gate net ..which reference book is prefer
How did you write the products n their structure I couldn't get it at all.
I cant understand the language ... what do you mean by L, R or 1, 2? pls clarify it
Mam last example main thora doubt hain aur apne Jo end of the reaction main kaha ki iski stereo kuch vi rakh lo farak nahi padega but Apne tu kaha tha left wale ko agar wedge main Rakha tu sob left wale ko wedge main hi rakhne padega....mam please explain it again 🥺🥺
Nice explaination n effort Mam...
Thanks you so much Madam ....
Didi , apne Diels-Alder reaction ka Streo wala portion jo yaha karaya hai , woh Clayden se match nehin kar raha . Apne Diene par L hone par Above the plane likha hai ,par clayden pe Below the plane kiya gaya hai.
Mam aap itne achchhe kyo ho ☺️
Mam what is 2+2+2 cyclo addition could u expain please...a small doubt
You can use some English terminology during technical explanation otherwise fantastic mam from Mysure university manasagangotri
You're teaching knowledge and i can see you're but i can't understand the language you're using. Please in other updates do well to ue English that will be a big help for us English students. Thank you
Last question m 6 π system h to trans ka trans hi rahega naa,, agr kisi ko aur bhi doubt h to pls rply
Last example thoda samjh nhi aaya mam....but overall it was awesome lecture
in reaction time resonances effect molecular orbital change the system like ( ++ - - resonace -++-)
bond formation time cyclopentadiene tow bond ++ -- by resonance + -- + and react with succinic anhydride ++ orbital and make bond
Why we are flipping the molecule for stereochemistry ...when they are making bond 1-2
Thank you mam
Mam, good morning... .mam plz clear my doubts.....if I don't want do PhD after quallify net exam then what are other career opportunities .....could you suggest smthing.....
Please make organic chemistry net prospective lecture
the exo product is more stable and lower in energy and therefore thermodynamically favored.
Ma'am aapne D A reaction ka Ortho para selective rules nahi bataya Kya ye important nahi hai
Ma'am also teach photochemistry after this.. That would be beneficial for students like me.
Yes mam..... Also make ur video on photochemistry...
Mam ye 1or 2 numbering hum kiske according krenge. Koi rule h kya iska. Mam kbhi exam me hum apni mrzi se dale numbring or vo wrong ho mam plz give ur imp suggestions
This is only a trick how to solve the Question quickly
I hve studied the whole pericyclic here😆
Mam I hv qsn that agr endo Pdt kcp h to hum jante h ki kcp less stable hote h after some time and heat wo log TCP me convert ho jate h TCP more stable hote h then apne endo Pdt ko stable q bola
Kuch books me endo Pdt less stable bol rhe h
mam isme coo-Me kese aaya isme to co-Me aana chahiye na isme ak 'o' nhi he
Excuse me mam kya organic worth krti h ittna effort...
Bcoz exam m organic k qus attempt krne m bhut problem hoti h..
And someone says me ki agr organic krni h to clayden carruthers pddni pdegi
Plzzz tell me ur email id
jchemistry001@gmail.com
Thank you so much mam🙏🙏🙏🙏
Thank you so much for this video👌👍
Too complicated....bt I really appreciate your efforts 👍
Ma'am apne NET online coaching ley kar crack kya ya ghar mey padke???
Left and right... In which prospects you r observing maam... It confused me a lot.. Please clear my confusion
It is very easy to understand left and right position .Double bond se jo aapki left side h vo left and jo right side h vo right or ji left side honge onki stereochemistry same hogi or Jo right side honge onki same hogi.
Playlist dikh nahi Rahi
21:20 mein COOMe ki and uske adjacent Me ki stereo kese pata chalegi ......stereo change hota hai toh endo aur exo bhi change ho jata hai
Very nice mam
Nice explanation 👍
Whose transition state is more stable .. Endo or exo
Endo
Mam pls explain in English separate vedio.more will see madam from tn
Mam 4.32 to time per aapane Jo concept batya hai wo galat hai because Jaha Endo product Hai woh ab Exo product Banega because interaction in between carbonyl group and 2 carbon location is not available
VERY GOOD MORNING JOYTI MAM VERY NICE TEACHING
Great mam
❤️
Tricks are so confusing...not getting what should we apply
Playlist is not available...
th-cam.com/play/PLYXnZUqtB3K9-SOwqZiHigO8leI6qMZX_.html
Sound quality Sahi kariye mam
Thank you ma'am dout clear ho gya
Good explaination mam
Mam koi book suggest kardo iss chapter ko padne k liye
Clayden
Mujhe samajh nhi aaya ye pehli baar hua hai ... Ma'am ke lectures se.
awesome trick...
Well explained maam
U r the best...
Madam use some colour chalks in stereo chemistry
I know youre one of the best teacher, but why you ended up with hindi known students alone why dont you consider we South indian students 😢
11:38 mey ma'am symmetry operation to match nahi hua
thanks 🤗🤗🤗
Good explanation mam
thanku mam 😊
keep it up!
