13:25 you said Nucleophile will attack on axial posistion. Even if it attacks equatorial posistion. We will get the same product. (But the intermediate will have -OH and -Br at opposite positions i.e., Br will be ortho to -OCH3 and -OH will be meta to -OCH3 ). Since Br and OH will have different stereochemistry, product will be same.
It is my first time I've been go through your video...and it really really a wonderful learning of organic for me... since I've physical chemistry as specialisation I'm too bad in organic chemistry....and because of which i always lose my NET JRF ... So thanks a lot yr... Keep uploading organic vedios specially in reagents and reactions concepts... 😊
The way you are explaining each and everything in detail that is awesome Means there is no chance for doubts Our doubts get cleared before they appear Thank you so much for uploading your vedios on you tube
Your way of teaching is fantastic...even your tutorials are hindi but it's useful. I got understand from your explanation. am from Tamilnadu .really really your class is very useful. I was completed my PG in 2011. Thanks a lot. Keeit up

Hello mam apke videos bahot hi jyada useful rahe hai . But yaha pr muje ek doubt aya h Apne bola tha ki agar benzene pr ome group ho to down side mein oxygen lagta hai But apne example (1st ) mein jab ome group tha fir b up side se o lagay to koi reason h kya uske pi6e ??? (Epoxide k cash mein ) ( jo last mein apne example kravaie. Usme apne Jo birch reduction vala example tha usme apne oxygen ki stereochemistry same hi rakhi hai so yeh ek doubt h so mam plz ise solve krvana ...)
Nice lecture mam...plz ...use English language also in the time of important sentences of the lecture.. that will be very helpful to non-Hindi students.. thank-you
At 14.20 , NaOH is not that strong base to deprotonate alkyl alcohol. Instead, OH will replace Br directly and then positive charge generated will be removed by deprotonation by base.
congratulations to you for bringing videos to the chemistry students.......I definitely can understand that you are well read and learnt all the concepts thoroughly......I appreciate you in this regard for your hard work that you have put into to get top rank in CSIR.. In this regard, I wish to inform you that 1)all the videos should be in English so that event the students who do not know hindi can understand 2) You are teaching and your conceptual explanation is so fast that it will be difficult to understand for a learner and an average student. ALWAYS TEACH IN SUCH A WAY THAT LEARNER UNDERSTANDS THE CONCEPT THOROUGHLY 3) Only the students who already has the idea on the subject can follow ...but difficult for a learner to reach you........Let the concept be explained completely in English slowly.....absolutely no hurry at all...let it take no.of videos on the reagent ....no problem ...you are teaching with such a speed and hurry that some one is chasing you . why so hurry........ go little bit slowly.....Think about the real class room......if you teach with this speed in the real class room, many students definitely cannot follow.... How you have learnt and how your teachers taught you in the class room......did your teachers teach you in the real class room like this....no........did you learn the concepts in this way.....no.......learning needs thorough understanding of basics and students need to give time to apprehend and understand the concepts...... also one more suggestion I wish to tell you is that when you are writing mechanisms......don't be in a hurry.....write all the steps on by one clearly....so that a learner understands and appreciates the mechanisms.....I have gone through the different videos on mechanisms...bu very few videos are there that reaches the students......video are for learning concepts thoroughly.....not just dumping information with full pace like shoab aktars pace bowling....... ....you are writing one step ..erasing and immediately explaining the next following on the same ......no need to explain in this way...... In this particular video, first explain the mechanism of epoxide formation (Dont forget to write lone pairs on oxygen , nitrogen , halogen and their anoins and also on hydride ion.).......If you read the Organic chemistry by Graham solomons , then you will know the the source of electrons is from lone pairs....not from negative charge...........then regioselectivity .....then stereoselectivity and then different examples.....same content you can teach in three videos....then no doubt it will reach many many students....and you will get more likes also. I wish you all the best......and wish you all success...
Mam in meisenheimer rearrangement if N nd double bond both r present in substrate..nd mcpba is given..we form N oxide instead of epoxidising double bond...why.?
The oxygen is electron deficient ...so it requires electrons ...so for heteroatoms which contain lone pair of electrons, oxides are formed since lone pair of electrons are more easily available for donation as compared to π electrons of double bond
Maam in the 1 st question we have 2 possibilities of attack but the 2 products we get are itself meso, so if there is a question asking how many products are formed in the reaction then the ans has to be 1?? Correct
Mam I got a small doubt ....in last question .....benzene converts from aromatic to nonaromatic soooo....which is correct among them ....(reaction with BF3)

Thank you very much madam, I feel very happy to seen this vedio, especially your way teaching is excellent for us (learners).
I realize I am kind of randomly asking but do anybody know a good site to stream newly released movies online ?
@Joel Eugene Lately I have been using Flixzone. Just google for it =)
@Raul Jasiah yup, been using Flixzone for since april myself =)

NBS mai benzene ring involve nhi hoti na...
which one has greater tendency towards epoxidation between cis alkene and trans alkene by m-CPBA?
Hello mam apke videos bahot hi jyada useful rahe hai .
But yaha pr muje ek doubt aya h
Apne bola tha ki agar benzene pr ome group ho to down side mein oxygen lagta hai
But apne example (1st ) mein jab ome group tha fir b up side se o lagay to koi reason h kya uske pi6e ??? (Epoxide k cash mein ) ( jo last mein apne example kravaie.

ma'am why difluoro peracetic acid does epoxidation with Bayer-Villiger oxidation.
How to distinguish as of when will Mcbpa will give epoxidationa and when will it Give BVO when Both carbonyl and Double bond are present ?
O-difluroperbenzoic acid gives both Bayer villiger and Epoxidation. Does it requires 2 equivalents of the Peracid or it does works with just 1 eq?
Even if a single equivalent is mentioned.. you do both the reactions together ....thats what is written in the book
@@JChemistry thnks mam
@@JChemistry in which book is it mentioned mam??
Nice lecture mam...plz ...use English language also in the time of important sentences of the lecture.. that will be very helpful to non-Hindi students.. thank-you

Its really helpful...🙏🙏
mam your written N,bromo pthalamide insted of N broom succinamide in structure
At 14.20 , NaOH is not that strong base to deprotonate alkyl alcohol. Instead, OH will replace Br directly and then positive charge generated will be removed by deprotonation by base.
30% NaoH is taken actually
Thank you so much mam🙏🙏🙏🙏🙏
May you always be happy 🤔🤔🤔🤔🤔,,, ,, ,,,, ,,,,,,,,,,,,,a your fannnn
mam but n bromo succinimide toh allylic bromination karwata hei na?
Toh aise kaise ho gaya
NBS does allylic Bromination in the presence of light (hv) otherwise it will act as shown in the video.

Crystal clear explanation mam...
Maam in the 1 st question we have 2 possibilities of attack but the 2 products we get are itself meso, so if there is a question asking how many products are formed in the reaction then the ans has to be 1?? Correct
NBS does allylic substitution ??
mam structure of NBS is not that what u have drawn.....u have drawn N-bromo thalimide.
Mam organic chemistry me claydan se koun-koun se chapter ko padhna hi. Plssss uske chapter Number ko btaye🙏🙏
Mam please suggest me a book of oxidation and reduction other than Caruthers because is main mechanism nahi hain
what is the alternative green reagent of m_cpba
Amazing video
Mam I got a small doubt ....in last question .....benzene converts from aromatic to nonaromatic soooo....which is correct among them ....(reaction with BF3)
Baut sahi mam please continue it.....
Mam no benzene ring in NBS....please kindly note that
Mam plz suggest book for theory of reagents to gain deeper knowledge
Mam class slide provide hi skti hai kya
hello mam i am a student of post graduation of chemical science , mam can u tell me that u do u provide offline coaching classes of Net CSIR????

You teach very well and precise but the audio quality is very poor in this video
The structure for NBS which you have written was wrong, ie Pthalimide, NBS is aliphatic succinic acid cyclic amide
Thank you mam
Maam u r so fine tuned in explaining..can u pls make video on other REAGENTS plssss
I'll upload one reagent everyday
Keep learning :)
In NBs structure remove benzene group mam
Y,it's correct structure
