Very nice explanation... Good job Mam...one of the best platform for all aspirants of CSIR net exam and Gate exam also... Thankyou so much once again Mam
Maam at 20.14 in the eg of cyclopentan-1,2-dione all ch2 are enantiotopic due to which 1 signal and bisecting protons 2 diff signals so total signals must be 3 , isn't it , i have a doubt here ?
19:51 par jo example hain uska signal 2 aana chahiye na ki 4... Ek pos paper ke plane se bhi jayega jo upar ke dono Hydrogen ko same batayega.. So two signal not 4..
Mam aap hmesha bhut acha explain krte ho .Maine aapki mostly sari videos dekhkr hi apne concept develop kiye hai but mam iss video me bhut sari confusion hai aapne c2axis khi li hai aur khi nhi li jbki axis of symmetry possible thi..aur answer me b .kuch confusion hai..I request mam plzz iss topic prr ek video bnna dijiye plzz mam bhut zada confusion horhi hai...
I have doubt In Q 16 and 19 . In Q 16 ...pos is present therefore 2 enantiotopic hydrogens and 2 disttreotopic but in Q 19 there are also 2 disttreotopic hydrogens which are not considered
At 22.03, u say 3 signal but according to the POS both H bisect the plane and give 2 type of proton as u consider in tetrahydrofuran. plz explain it mam
ma'am 1st u told to see whether the molecule has C2 or not...if C2 is present then u said do not look for POS ..but in examples of THF and uske baad wala bhi..usmai dono mai C2 hai...n u din't consider that...toh aise toh answer alag ayenge na maam
Mam aapne jo 6th example right side board mein top mein draw kiye ch3ch2ch2ch2ch3 to usme mam dono side ke c2h5 ek hi signal denge na mam hum dono alag alag kyun le rhe hai I mean ch2 ke do aur CH3 ke do
There should be 2 signals only As the bridged carbon containing single H has connected to -CH2 groups on both sides so same environment 1 signal And for non bridged Carbons, both are connected to -CH groups (bridged C) so again they have same environment so 1peak for them So in total 2 peaks [1 for - CH2 groups(non bidged C atom) and 1 for -CH groups (bridged C atoms) Hope you get it
If I were 2 give feedback here....go slow n speak clearly or rather remove background noises....on the other hand,I understood...thanks 2 my tuition classes.. previously,I missed certain parts in my class,so that's why I came here....if I would have watched this in the first place,I may not hv understood...I meant both were equally needed... Now I'm pressing enter button,I knw noone will read my comment 😂😂
Tetrahydro furan will show 2 signals...since the Protons in each CH2 are enantiotopic
Please mam share a video of thermodynamics and statistical thermodynamics videos
Ye linear chain main b 2 signal hi aayege mam.. plz check kerna
Ma'am, then what about 1,2 cyclopentadione? In that case also 2 is the answer or 4 as explained in the video
Also doubt in bycyclo 1,1,0 butane someone plz clarify 🙏
Madam I feel where oxygen is in plane there it will be two types of proton
mam aapki teaching method aur aapki soberness bahut achha lgta hai simplicity , bahut achhi lgti aapki simplicity
Very nice explanation... Good job Mam...one of the best platform for all aspirants of CSIR net exam and Gate exam also... Thankyou so much once again Mam
Mem you teach very well and understand every term in a good way
Kya explanation dete ho aap
Big fan of you 🌹🌹🌹
Mam 11:20 pe jo solve karna start kiya hai question usme chcl ke saath wala diastereotopic hoga usse next to nahi hona chahiye
बहुत शानदार
Very easy method use for explaining
Awesome teaching
20:12 there will be 2 signals I guess, u did 4? Plz reply mam
Yes you are correct. There will be only 2 signals.
thank you so much! meri degree aapke bharose nikalne wali hai!!!
22:03 please explain ..it is 2 signals right?
Yes
Yes bcoz horizontal plane is also present
Mam there is doubt in question from time 22:11 till last 25:12
Thanks didu 😊😊😊
13:09 example answer 7 signal
There will be mirror image in middle of the molecule
No
It's not mirror image see properly
Thnx..mam very well explained😊👍
Thanks you so much yrr paper ke time syllabus complete krane k liye
🤗🤗
Mam please explain 22:12 pr Apne ye kaise smjhaya eska to 4 signal aane chye na jab plane dalege to 4 aayge na 2 kaise aaye
Be continue.....💐💐💐💐👌
At 20:14, u said that 4 signal .But mam isme 3 signal ayenge ?
3 signal
Yep 3
Yes
Yep 3, because the diastereotopic hydrogen s will show same signal
Bhai NMR ke liye kaunsa book padhate ho
At 19:48 , according to you THF will give 4peaks but when i searched on Google i find out that it give only two peaks .
Yes that's my mistake
The answer will be 2 only
Thank you mam.
At 19:37 the molecule has plane of symmetry of the two hydrogen should be same mam
Ma'am 20:13 iss molecule mein C2 axis hai na...phir ye homotopic hone chahiye na
13:30 expecting same 🤣🤣
At 21:40, All 4H are same becoz Dere is no chiral centre to make dem distereotopic. So total signal shld be two.
Plz dear clear my doubt...
you're right but there is 2 hydrogens above the plane&2 hydrogens below the plane.so they give separately 2 different signals
@yenda Varun Kumar
It doesnt matter if they are above the plane or below the plane they are homotopic
I think this is your first video, that I was unable to understand.
At 21:57 if we see plane of symmetry then the two hydrogen should show different signal
Jonty Kathuria I think same
Same doubt mam
I have same dought. I think instead of 3 it may be 4 signals
nice observation
Outstanding explaination..
Very nice explanation
Superb lecture
Very nice mam ,mam Kya aap keval video upload karti h ki online padhati h
12:40 around 9 signal nii; 8 hone chahiye kyuki dono ch3 ch2 se hi attached h n.
Yes 8 signals hoga
Thank you so very much ma'am 🙏🏻
Explained really well
Maam at 20.14 in the eg of cyclopentan-1,2-dione all ch2 are enantiotopic due to which 1 signal and bisecting protons 2 diff signals so total signals must be 3 , isn't it , i have a doubt here ?
Bisecting protons ni hai yhan
19:51 par jo example hain uska signal 2 aana chahiye na ki 4...
Ek pos paper ke plane se bhi jayega jo upar ke dono Hydrogen ko same batayega..
So two signal not 4..
Yes..that's my mistake ...H in every CH2 are enantiotopic ...therefore will give same signal
2 nhi 3 signal aayenge i think
yes but there c2 is also present so why havent we r considering c2 plz answerr
Mam aap hmesha bhut acha explain krte ho .Maine aapki mostly sari videos dekhkr hi apne concept develop kiye hai but mam iss video me bhut sari confusion hai aapne c2axis khi li hai aur khi nhi li jbki axis of symmetry possible thi..aur answer me b .kuch confusion hai..I request mam plzz iss topic prr ek video bnna dijiye plzz mam bhut zada confusion horhi hai...
Yes...I also hove confusion about C2 axis....and in stereochemistry lectures mam told first to check C 2 axis and then PoS
Mam please teach in English yours explanation is well 👍👍👍.
Mam at 11:13 example 5; two methyl groups are present near to cl and third one is away from it...is it not so?
If 2H atoms are beside a chiral centre then they are diastereotopic but if they are separated by more than one carbon then they becomes enantiotopic
Please clarify this doubt
AWESOME MAM
I have doubt In Q 16 and 19 . In Q 16 ...pos is present therefore 2 enantiotopic hydrogens and 2 disttreotopic but in Q 19 there are also 2 disttreotopic hydrogens which are not considered
Great explanation
Ma'am there are only two signals for THF but u had written 4 for it so why?
Madam I want to know how to predict H NMR of sulfurous acid 2 ethyl hexyl isohexyl ester C14H30 O3S
crystal clear mam ji
20:03 there must be 2 signals. Kindly check
Mam tetra hydro furan gives 2signals instead of 4
Yes
awesome explained
Mam we don't need tricks.... We can understand and learn the concept......
Thank you very much mam 😊
Mass spectroscopy ki problem please upload kariye mam
At 22.03, u say 3 signal but according to the POS both H bisect the plane and give 2 type of proton as u consider in tetrahydrofuran. plz explain it mam
If both H present on same carbon only we consider them as diastereotopic I think so
ma'am 1st u told to see whether the molecule has C2 or not...if C2 is present then u said do not look for POS ..but in examples of THF and uske baad wala bhi..usmai dono mai C2 hai...n u din't consider that...toh aise toh answer alag ayenge na maam
THF seems to have 2 signal. I am also confused here.
Mam aapne jo 6th example right side board mein top mein draw kiye ch3ch2ch2ch2ch3 to usme mam dono side ke c2h5 ek hi signal denge na mam hum dono alag alag kyun le rhe hai I mean ch2 ke do aur CH3 ke do
mam why THF is having 4 nmr signals
Kindly primary secondary or tertiary alcohol ma no of signal ketny hn spliting kasy kindly bta dnn
Best mam
Madam 20.01 in that example signal are only 3 we get how 4 possible
Ma'am Great explanation, but I can't understand a 21.57 min why will it show 3 signals not 4 signals? Please explain
There should be 2 signals only
As the bridged carbon containing single H has connected to -CH2 groups on both sides so same environment 1 signal
And for non bridged Carbons, both are connected to -CH groups (bridged C) so again they have same environment so 1peak for them
So in total 2 peaks [1 for - CH2 groups(non bidged C atom) and 1 for -CH groups (bridged C atoms)
Hope you get it
Stracture ko noming k sath btao na didi qki exam mostly naam diye rhte hai to please stracture k sath naam bhi btao alkane ka
Why in propane the middle carbon hydrogen has higher delta value?
mam bhit sare example me doubt h ap plz ek lecture iske upr bna dijiye
ap c2 bhi consider nh kr rhe ho bhot confusion h mam plz help
mam i could not understand clearly 😐😐😐
Kya 1 he hydrogen 2 signals de sakta h?? Possible h?
If I were 2 give feedback here....go slow n speak clearly or rather remove background noises....on the other hand,I understood...thanks 2 my tuition classes.. previously,I missed certain parts in my class,so that's why I came here....if I would have watched this in the first place,I may not hv understood...I meant both were equally needed...
Now I'm pressing enter button,I knw noone will read my comment 😂😂
Mam cis trans kese dekhte h
Thanks Ma'am
at 20.14 mam should not be there 2 signals ?...
CH3-CH2-OH k kitne signals honge mam? ... Please answer
3
Very helpful
CYCLOBUTANE ka plz explain kro bridge valo ka different aega yaha to kunki bisect ho
rh h
chemical enviourment is most importsnt thing .diasterotopic tbhi hoga jb chemically differet ho ..or vice versa...ok
Tetra hydro furan has 2 signals mam,not 4
Yes , that's true
Mam can you plzzz explain the eg. At 22.48
How many signals will it have in toluin , ma'am
Good job...
Mam can you plzz explain the last two examples
Mam why neopently chloride do not split please reply anyone????
Mam, 2-chlorobutane me book me 4 signals diye h kya ye sahi h? If it is correct then tell me please how.
mam muse mail kare answer of dimethylformaamide ke signal at rt and at 295
net csir me first exam me only subject hi aata h kya
awesome
Plz upload raman spectroscopy's vdo
Sure :)
Yes ma'am
Norborne type of signal
Cyclopentane also has plane of symmetry and two H's on the one corner are being cut by plane of symmetry then how come it shows only 1 signal???
mam
how many signal does propene give?
Thank you mam g
Can we give iit jam if I'm pcb from cbse and maths from NIOS????
Yes you can
@@JChemistry Thanks mam
You said that 2 protons of cis stilbene is enantiotopic...but cis stilbene has c2 axis..so why it is not homotopic?
Enantiotopic ni hoga wo to diastereotopic hoga na... q k chiral center jab banta h to wo diastereotopic ban jata h
Thanks mam.....
Ap ka notes mil jayega massbauer ka mem
Cyclobutane mein to POS dono protons ko bisect kar raha hein toh wahaan par dono protons k same single kyun aaye?
Theek hai 😁😁😁
Mam please make videos on structure determination.
I'll be solving previous year questions of spectroscopy soon ..from there you can learn structure determination too
19:40 how it has 4 signals. Which one is the chiral carbon. Isn't it would be 2 signals
Mam how many signal in case of cyclohexane
There will be two signal for cyclohexane at low temperature but at room temperature only one signal will be there.
8:38 me 4 signal hoga
For THF there supposed to be 2 signals, you are explaining it as 4 can you please elaborate
Sry now I saw your comment 👍
Mam aap clear ny bolte aur jo likhte ho wo v clear ny hy baki explanation mast hy
