The best teacher of chemistry on youtube
Finally I am felling like.. Stereochemisty is very interesting from you maM.... Thank you So much..
Ma'am please made videos on physical... Kinetics + thermo + electrochemistry +.....
Stereochemistry is becoming very interesting due to the direction of mam. Thank you so much mam
This is a great video to understand topicity. If there were subtitles it would be better for people who don’t speak Hindi/Urdu.
But thank you very much!
In 20.20 minute, the protons of Propane will be homotopic. It can't be diasteteotopic because in diastereomers there must be a chiral center relative to the concerned center.
Yes that's true....I was just trying to show you the bisection of protons by POS ....I wasn't saying the protons in propane will be diastereotopic
Thank u so much ma'am ....all video's r superb nd easy to understand 🙏😇
Thank you mam..I am very confusing about the concept of topicity of Different Homotopic,Enantiotopic,and Diasteriotopic..😑😑😑🙄
Ma'am 20:27 pe C2 Axis pe cut karne se do side equal hota hain,toh homotopic hona chahiye
World best teacher in chemistry field
Mam, at 20.27 there is a C2 symmetry ..so it should be homotopic ..then how it will be diastereotopic..plz explain
I'm doing practice again from this video Ma'am 😍
Mam 44:44 pr aapne C2 present hone k Baad v plane of symmetry check ki jbki aapne btaya tha ki C2 agr present h to further check nhi krna h
Mam how to calculate resonance energy ..... In structure and reactivity unit can u make a video plz mam
Well done mam ....u r pack of energy .....Thoda confusing ho gaya kai topic aur vefios ek sath hai baar baar repeat karungi may be clear ho jayega ...Thank you mam
I didn't understand enantiotopic and diastereotopic protons mam. Kindly help.
I have doubt went hydrogen is reflecting and wen it is bisecting.... Aisa h kya wen hydrogen present at same carbon then they are bisecting and wen the plane ia pasing and they present at different carbon i.e reflection... 25.05 first example that hydrogen will bisect each other.. Isn't it
Sorry mam , thoda confuse loga , inq.5 , u said no C2 axis coz of back side ch3.
But in q.6 U said C2axis exist coz .mixed up
Mam at 25.06 how Hb and Hc are diastereotropic please confirm
I have the same doubt. Hb and Hc are both trans to Ha/Cl. Then how can this be true. Please confirm madam #jchemistry
Yes .. feel the same HB &hc are in cis position . Both are trans to Ha and cl . How it will be dia
No they are not diastereotopic
I think they are cis to each other
@@soniyathakur1739 if cis or trans relationship seen they are diastereotopic.
32:45 minute py,
1st molecule k oper waly dono proton diastereotopic hen aur 2nd molecule k b oper waly dono proton ki b same wohi position hy jo 1st molecule k oper waly dono ki hy,
To phir 2nd waly homotropic kesy howe ????
Kindly bta den
Mam how to predict axial and equitorial groups from group which are above and below the plane?
Mam pls make videos on homotopic, enantiotopic nd diastereotopic phases. It is very confusing for me .
Mam last norborene m pos h tho both protons are enantiomeric ......
You are a very very very good ....... talented teacher
Ha and Hc are mentioned diastereotopic, in second and third molecule (reference chloro substituted cyclo butane) , they are both cis with respect to each other and trans with respect to chlorine, why?
thank you di
please make videos on grp theory and photochemistry
In the last example around 42 min. If POS is applied, then Ha and Hb will be reflecting eachother. Can you please explain the same?
Yes
Enantiotopic
At 38:23 secs the first molecule..is seeming..doubtful regarding homo and hetero it can be both I think..
If the plane passes through Ha and Hb (both in one plane) cutting them across..
Then it should be Diastereo topic na..
And if the molecule is cut just perpendicular to previously chosen axis.. Then enantiotopic..
And as u taught homotopic is clear..
But which one is correct..mam😇..
I will be thankful if my doubt gets cleared..
♥️J chemistry
If such situation arises in any molecule, then consider it to be homotopic.
Mam last s 3 example m apne 3 chiral center mark kie but wo H.
Chiral center kaise h??? Confusion h.. Mam please clear
..
You are best teacher mam, thank you
Best teacher of chemistry that i have ever seen
Big compliment.
Thank you 🌺
@@JChemistry please upload some videos of thermodynamics it will help us alot
Can we write this topic in theoretical way in BSC exam?
No issue dear...
Bahut acha explain karti hai :)
Mam this video is not or yes for bsc level or jam level?
Ma'am apne homotopic or diastereotopic proton btane k liye same molecule ka use kis h ...fir differentiate kese krenge
aaje to lechar maj badhu net puru thay gayu.... thank you madam
At 40.02 mins how the proton are disteriotopic? As a plane is reflecting the protons so it will be enantiotropic?
No it is disteriotopic.beacuse Ha proton is in equitorial and Hb proton is in axial so relation between them diastreotopic..
20:37 if i insert POS through both the (-CH3), then what?
At 33.01 the first two examples are similar,how at one time be enantiotopic and other is homotopic? Ma'am can you give more examples on cyclopropane with different substituents on topocity?
Same Doubt. Diastereotopic nhi hoga @21:09 , homotopic hona chahiye
I was checking comments just to know if I'm the only wrong one to understand or others too have same doubt.
Best chemistry teacher in India
Sister, can you plz explain re & si face ..m bit confused...
Iss video me aap bahut sad lag rhe
Ho . but aap hasate hue hi bahut achhe lagate h
Didi ji little bit confusing but u explained well i will try it again n agin
In norborane system(39:10) u cn rmbr tht two endo protons r enantiotopic........also two exo H r enantiotopic but an exo and endo are mutually diastereotopic.
@geeta dhiman are you sure in that concept?
extremely useful video. There were lot of examples really a worth one
All problems on stereochemistry has been clear because of you .
Thanks mam
JAZAKILLAH ALLAH apko khush rakhe bhot ❤❤❤❤❤❤❤❤
Nice mam 🙏finally l fall Love into stereo chemistry.
I didn't understood bcoz lack of hindhi 😥😥😥
In Which language do you understand ? Even your English is not good.
From which state are you?
Mam thank you soo much for uploading stereochemistry videos till part 6 please upload remaining 6 parts also.I am having gate exam within one week.So please upload all the videos mam.Its a humble request
Mam please upload all the parts of stereochemistry..🙏
mam apne jo last example btaya usme c2 axis s bhi check kr skte the n hum ??????.................ya fir double bond k case m ni lgate c2 axis?
please answer mam
In 35:30 how diagonal chloride ions are interchanged when c2 axis is passed through center ??😊
20 mins me C2 axis hai ... that's why wahan dono Hydrogens homotopic honge!!!
1st example me ap k method k according enantiotopic kesg hu gy??jesy apny plane pass ki.h os k according H to reflect krein gy lakin phenyl group and methyl group ek dosry k samny hu gy...to ap k method k according ye wali plane to h hi nhi molecule me jo apny pass ki h
Mam at 25.05, Hb and Hc are diastereotopic? Can u recheck it and plz confirm ?
Thnx mam
Please suggest the good reference book for stereochemistry in gate and net exam point of view
Nasipuri
@@JChemistry Ohk Thank you mam
Mam, apne puri Jan lga di....best of luck
Mam at 20:27 what example u have taken that should be homotopic,given is not chiral,both CH3 are on plane, so we can't find out the configuration as well even after replace with any other atom and there is a C2 symmetry,so it should be homotopic.. kindly check once.
In 26:01, Will Ha & Hc become enantiotopic or not by passing plane in mid?
No because there is no symmetry wrt Cl
At 30:40 why are we bisecting 2 H..Ha and Hb...we can also pass a plane that will reflect Ha and Hb and bisect CH3 and H on both side...
than top and bottom groups are different we cant bisect like this
Aap plane (pos) kese pass krte hain usmain dout hain
thankyou so much mam,it helped to build my concept
Wonderful explanation...sis
Really teaching good madm you told at the end i dont have teaching experience. But i learned a lot from you. I also cleared SLET, PhD but your method of teaching awesome.
Thanku so much ma'am nice way pf teaching
Mam, agar kisi molecule mai C2 na hoker C3, C4 ya Cn axis of symmetry ho toh kya wa bi Homotopic honga??
Ur teaching is good pls upload the videos english instead of hindi
Mam please explain the difference between assymetric centre and chiral centre.. Getting confused
Mam how to draw Fischer of nor bornyl compounds?
Thank you ...this is really helpful 😊
Can u pls take in English
Thank you ma'am
Mam ...plz.explain configurational ..- conformational isomer in ..cyclohexane in chair form....also...
Mam pliz made video on nuclear chemistry
NH3 has C3 axis,mam if it is not homotopic,is it heterotopic?
At 33:55 how the phenyl gp is homotectic...??? After rotation the stereochemistry of phenyl gp is changed at that carbon
Homotopic*
Ma'am jo diastereotropic hein woh toh homotopic bhi hein . Differentiate kese karenge?
mam aapne kaha tha k iek baar c2 symmetry dekhne k baad heterotropic check nahi karte phir aapne 35 -36 minute mein c2v symmetry ensure hone par heterotropic kyun check kiya
Par 38.45 par diaesteriotopic Nahi Hoga kya? Mam please reply .......
Thank you soo much mam
Thank you so much maam
Can you do different type of example problem solving in this topic ?
NOT YET CLEAR
20.36 it have c2 then how can it be diastero topic
40:05 par 3 chiral centres kaise aa rahe h? I didn't understand plz explain
aa rhe h 3 chiral centres one by one carbon ko lekar dekho with hydrogen ...
Dono bridghead position par dekho different substitution hein or ak udhar jaha Ha and Hb hein after by cholorine atom replacement
Mam, very confused 😥😥
Physical pr video bnao plz
Mam 14:50 me jb C k around 4 atom revolve ho rha h to C-2axis kyo
C-4 kyo ni
Mam ap answer nhi krti h.... Doubts clear ni krti😔😔
At 37.03 pe plane lgaya h wo 7 and 8 ok reflect krega to enantiotopic hone chahia but jb C2 axis lgaya tb ye interchange kr rahe the to homotopic the....plz clear this concept
Here the priority of C2 axis is higher than a plan as mam talked about it previously.so we consider C2 here
Good work keep it up !!
:)
Madam nadathidu marachita epdi madam therium aparam munnadi vanthu marachikiringa una pakkanununa una matum video podunga madam onnu therla
