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 ?
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
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
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
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
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..
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
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
mam aapki teaching method aur aapki soberness bahut achha lgta hai simplicity , bahut achhi lgti aapki simplicity
Mem you teach very well and understand every term in a good way
बहुत शानदार
Mam 11:20 pe jo solve karna start kiya hai question usme chcl ke saath wala diastereotopic hoga usse next to nahi hona chahiye
Kya explanation dete ho aap
Big fan of you 🌹🌹🌹
Very easy method use for explaining
Awesome teaching
thank you so much! meri degree aapke bharose nikalne wali hai!!!
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.
Superb lecture
Thanks didu 😊😊😊
22:03 please explain ..it is 2 signals right?
Yes
Be continue.....💐💐💐💐👌
Outstanding explaination..
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
Very nice explanation
Very nice mam ,mam Kya aap keval video upload karti h ki online padhati h
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
Thnx..mam very well explained😊👍
Thanks you so much yrr paper ke time syllabus complete krane k liye
🤗🤗
Mam there is doubt in question from time 22:11 till last 25:12
Explained really well
Ma'am there are only two signals for THF but u had written 4 for it so why?
Thanks you mam 🙏🏻🙏🏻
Ma'am 20:13 iss molecule mein C2 axis hai na...phir ye homotopic hone chahiye na
crystal clear mam ji
Great explanation
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
AWESOME MAM
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
At 19:37 the molecule has plane of symmetry of the two hydrogen should be same mam
Madam I want to know how to predict H NMR of sulfurous acid 2 ethyl hexyl isohexyl ester C14H30 O3S
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
Thank you mam good explanation
Thank you so very much ma'am 🙏🏻
Tq mam
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
Thank you mam
I think this is your first video, that I was unable to understand.
awesome explained
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
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
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
Yes ma'am
Mam tetra hydro furan gives 2signals instead of 4
Yes
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.
Thanks Ma'am
Thank you very much mam 😊
mam why THF is having 4 nmr signals
Kya 1 he hydrogen 2 signals de sakta h?? Possible h?
Best mam
at 20.14 mam should not be there 2 signals ?...
12:40 around 9 signal nii; 8 hone chahiye kyuki dono ch3 ch2 se hi attached h n.
Yes 8 signals hoga
awesome
Very helpful
Mam, 2-chlorobutane me book me 4 signals diye h kya ye sahi h? If it is correct then tell me please how.
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?
Madam 20.01 in that example signal are only 3 we get how 4 possible
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
CH3-CH2-OH k kitne signals honge mam? ... Please answer
3
Mam please teach in English yours explanation is well 👍👍👍.
Thank you mam g
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
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
Mam we don't need tricks.... We can understand and learn the concept......
How many signals will it have in toluin , ma'am
Kindly primary secondary or tertiary alcohol ma no of signal ketny hn spliting kasy kindly bta dnn
Thanks mam.....
13:30 expecting same 🤣🤣
You said that 2 protons of cis stilbene is enantiotopic...but cis stilbene has c2 axis..so why it is not homotopic?
13:09 example answer 7 signal
There will be mirror image in middle of the molecule
No
It's not mirror image see properly
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.
net csir me first exam me only subject hi aata h kya
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???
Tetra hydro furan has 2 signals mam,not 4
Yes , that's true
mam
how many signal does propene give?
Enantiotopic ni hoga wo to diastereotopic hoga na... q k chiral center jab banta h to wo diastereotopic ban jata h
Good job...
Cyclobutane mein to POS dono protons ko bisect kar raha hein toh wahaan par dono protons k same single kyun aaye?
Mam cis trans kese dekhte h
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
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
Mam can you plzzz explain the eg. At 22.48
Can we give iit jam if I'm pcb from cbse and maths from NIOS????
Yes you can
@@JChemistry Thanks mam
Mam why neopently chloride do not split please reply anyone????
For THF there supposed to be 2 signals, you are explaining it as 4 can you please elaborate
Sry now I saw your comment 👍
Mass spectroscopy ki problem please upload kariye mam
Di aap ne kon se coaching centre se coaching li h
Career endeavor
Mam can you plzz explain the last two examples
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.
Plz upload raman spectroscopy's vdo
Sure :)
Ap ka notes mil jayega massbauer ka mem
Hello maam apki online classes kese join kr skti hu?
New batch will be started from first week of June
You can join then by downloading J Chemistry app from the playstore
20:03 there must be 2 signals. Kindly check
🔥🔥🔥👍🏻
mam muse mail kare answer of dimethylformaamide ke signal at rt and at 295
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
