What a lecture mam outstanding the best lecture of spectroscopy in RUclips
The way u teach in every single video...nobody can do this for free....you r superb mam...
Best explanation of.. DBE...
जय हो... Jyoti di... Ki
Mam aap padati hi itna aachha ki samjh me na aay aisa to ho hi nhi sakta

Mam aap BADMAS rule follow nahi kar rahe hai 😕... wrong calculation
Your Sound Of Voice Is Just Unprecedented Awesome Ma'am
❤️ You Ma'am
Mam ur amazing muje apne hod ka kabhi samj nhi aaya but aapne it's amazing mam ur my fav mam 💕💕 love you mam
You made this topic easier to me.. please make a video on transition state theory as well
Excellent explanation...thanks for putting so much efforts dear
Thanx a lot mam specially u select que nd solve properly really we motivated
Bht hi accha explain Kiya mam aapne
Nice video
Mam for C4H6 .. triple bond will also possible right ?
For DBE -2 . One triple bond is also possible right .
Ya I was thinking the same
Thankyou so much mam. It was very useful to me.❤❤❤❤
Thankuuuu sooo much mam it's too useful
Thank u very much madm.i was very worried for nmr..now its okay.😊😊😊
Best lecture mam
Aoa..i am from pakistan & doing my MS in Chemistry. Ur lecture is very helpfull even in MS level. jazakillah😇Allah bless u ever.
Thank you mam
Dear maam, your teaching and especially problem solving are excellent.... kindly help me solving a problem provided with following information-
molecular weight- 286.24
UV - 253.2 and 348.1
IR - 3404, 3325, 3290, 3159, 1664, 1610
1H-NMR - 1H-d (6.18), 1H-d (6.37), 1H-s (6.62), 1H-d (6.82), 1H-d (7.42), 1H-s (9.41) and 1H-s (11.79)
13 C-NMR showed presence of 15 carbons with delta ppm (chemical shift ) at- 94, 99, 103, 104, 114, 115, 119, 130, 144, 148, 155, 156, 162, 164, 181
pagle kar denay wala question ha
Why divided with 13. When asking mol.wt
Thank you mam 💗
Nice mam great work
S we got it.
Ma'am, C4H6 ke structures me allene bhi toh possible h?
Jyada dimag ni lgana h
Thanks Ma'am
Thnk you so much mam.. You are extremely good..
Incredible teaching skills thxx
Good effort madam,
very good explanation mam.
❤❤❤
U r great maim nice video.thank U.
Easy to understand..

Mam aapne carrear endeavor se coaching ki hai kya... Aapke notes same hi hai?
👍
Beautiful and outstanding class
Just speechless
u made nmr very easy.... thanx
Great efforts mam......topic well understood
Thanku sososooooo much mam 😍
Didi in last question, why we doesn't consider "N" as per previous question.
This was very much helpful..thank you so much.
Thanks
its osome....mam
Thnxxx mam
Most lucid explanation 😍
Excellent explaination ...thnx a lot ma'am👍
mam isme jo aapne ring bnaii he jisme 10 btay he us me 10 carbon na hokr 11 carbon he or isme 3 ring na hokr 4 ring he
or aapkii abhi vdo ak dm best he
ad tkq you mam
Very nice
Excellent grip mam❤️
NYC lecture mam
Thank you mam g
Yeeehhhhhhh smaj me aaya heeee
Pyridine ka DBE 1 nhi arha Kia ? Num of carbon say minus krna hy na ? 5-4 1 hoga phir ?
Awesome explain mam
Thanks you mam 🙏🏻🙏🏻
You are awesome❤❤
Ma'am,ek question, state lecturer (ODISHA) ke competitive exams ka bhi yahi syllabus hoga na...Ya isse Kam ya isse zyada..
Pls reply sure.. Thanks
Thanks di
In which type questions we need to use dbe formula madam
Mam in 120 m.wt vale example me mo.wt ko 13 se kyu divide kiya???
C & H ka molecular mass ka sum : (12+1)
Ma'am you tube pr spectroscopy ki video part 1,2,3,4 delete krdi aapne
Delete show ho rha h you tube pr .
Good
Is Double bond Equivalence rule is always Correct for every molecule....?
DBE = C+1+N/2-H/2
I got stuck at C3H7NO formula.... Butanamide..... help me in this....?
👍
Outstanding
Ma'am NMR ki 1,2,3,4, video delete show ho rhi hai.kya aapne video delete kr di
❤
Mam why the nmr part1, 2,3,4 is not there.?
Mam,if M.W is even,then no. of 'N' is present even no.,but in case of 'O' is even/odd ??
Phir se gayb krneka kam krte hai ,,😝😝 very nise mam
Please show 4 video in nmr spectroscopy ...
Thank you ma'am ......
Awesome mam 🥰🥰🥰
Mam ir,uv,pmr,nmr combination problem series lona...
Mam Mai msc chemistry se hu first year
Kya Mai AAP ke video se study kr skta hu please
Thank u maam❤️❤️
mam isse phele ke video nahi show kar raye hai
Thnkuu mam🤗🤗
I understand well
The compound that exhibits following spectral
data is
'H NMR: 8.0 (d, J = 12.3 Hz, 1H), 7.7 (d, J=8.0 Hz, 2H), 6.8 (d, J = 8.0 Hz, 2H), 5.8 (d, J=12.3 Hz, 1H), 3.8 (s, 3H), 3.0 (s, 6H) ppm.
Please solve this mam
So good mam
Mam 13 se kyu divide karna hai ?
