Ma’am you are an excellent teacher. I’m a retired chemistry teacher (70-yr old )
Thank you so much for the encouraging words, Sir!
It means a lot to me.
Ky proof hai ?
😂@@JChemistry❤❤
At 21:42 mins, the molecule has centre of symmetry cos; so it will be an optically inactive molecule
Aapne constitutional isomer mein bromo gp lagaya to show different connectivity wrt to cis/trans dichloroalkene. Isomers must have same molecular formula
Past three days i'm watching ur videos about Stereo chemistry,very nice explanation 🙏,thank god i know hindi fluently😊,keep rocking mam💥
JAZAKILLAH ALLAH apko khush rakhe bhot ❤❤❤❤❤❤❤
Thnku so much jyoti mam.... Its suprb explanation... Brilliant...mujhe apke videos s hi stereo smjh aayi
You have extremely great quality of teaching..
I seriously feel blessed that i found your video. Thanku very mch.. God bless u.
Very happy by seeing subscribers increment..... I subscribe when there is only 7k....happy to follow your lectures
Glad to know that :)
at 28:52 min. a and c are not at all isomers rather 'c' should be geminal dichloride.
Very nice ma'am
didi your explanation muje bahot acha laga ...want more video (ORGANIC MAINLY)
mam aap bahur acche se samjhati hai ...thanks alot
Maam onething i wd suggest nevermind.. In meso compounds also having center of symmetry... As in case of meso tartaric acid while we do its staggered sawhorse conformation having a plane of symmetry also...
Yes definitely
Meso Compounds have COS as well as POS ....and they are optically inactive
very simple method of teaching without any complexity ....great mam
I am watching it for JEE ADVANCED,,It is helpful 😄,Thanks!Alot Didi
Mam, excellent work. I don't know hindi but as you write everything that you speak I could understand. Very dedicated
need to feel ashamed... You are a Indian
Ma'am 2,3-dihydroxy 1,4 but -dicarboxylic acid optically inactive hona chahiye because plane me rotate krne per superimpose ho ja the hai
Mam tartaric acid ke second example me jo threo form h usme bhi agar first str. Ko 180 degree rotate kar de to vo second par super imposable hogi to vo bhi optically inactive hona chahiye plz explain mam
At 20:10 min. Br and Cl are different group how can molecules be constitutional isomers?
Sorry at 28:50
Yeah same question
They are different compounds, watch the organic chemistry tutor
Yes same question ⁉️
At 37:25 the middle carbon from which POS is passing through. Can we say it pseudosymmetric or not?
Yes pseudoasymmetric
yes
Your explanation is so beautiful and teaching style is wonderful ma'am....🙏🙏
Mam u r fantastic... U r superb 👍👍🎊🎊
Last example in optical activity is active, how? Bcoz there is COS is present
At 22:12 the structure has COS then it must be Optically Inactive, right???
Yes I also noticed .... 🤔🤔🤔
Yes it is optically inactive....it has COS
Bich me se cut karne par upar ke carbon ka H left hai and niche vale carbon OH left mai hai Isliye o POS Show nhi krte isliye vho Opticaly Active hai
@@satyamkhedkar7742 COS ka kya?
Yup u r right
22:10 but these have centre of symmetry. Then why they are optically active.
You're the best. God bless you 🙏😭❤❤
You are really great mam.....
Mam I am new students of your channel.20 minutes e Jo example Apne Bola optical activie but there is centre of symmetry.how it will be then optically active???
thanks mam
Thank you mam so much..your teaching technique is unique and very helpful,,,😍😍🥰🥰
At 37.04 min,the central carbon containing OH on dash bond is chiral as per your part 4 video you said...!
Exactly my point!
How it's chiral according to you?
mam yu are really great teacher in the field of chemistry
Thank you so much mam 🙏🙏🙏🙏
Mam anti conformation of meso tartaric acid ka (i) present hai optically inactivehoga according to 3 codition for optically active
Thanks a lot mam....way u teaching awesome 🙏
Thank you mam 🙂
at 22:12 molecules have centre of symmetry but mam you are telling optically Active
No the molecule doesn't have centre of symmetry.(draw in Sawhorse)
Fisher projection doesn't have cos .just draw sawhorse of it
@@gauravsingh-fe3kw we can't draw all the projection in the exam
Thnku mam ❣️
Thanx di
Thanku di..u solved lot's of my problem this topic..ur teaching style mind blowing..I like it.. where are you from 🙏
Thanku so much mam
Awesome made my preparation easy🙏
22 min mai jo molecule hai ...usmai cos toh hai , toh yeh optically inactive hona chahiye ....cooh ke opposite cooh hai H ke diagonal H hai , OH ke diagonal OH hai ??????????????
Yes ... Ye molecule inactive hona chahia ....
Thank you so much mam for making this video 🙏🙏🙏
Thanks mam
At 35:31 though it doesn't have POS but it does have cos so how can we say it to be opticaly active?
It doesn't have cos, coz it's check from center, they are not at pera position. So it doesn't have cos
25:00
Optically active mai jo last example tha usme to COS present hai , to optically inactive hona cahiya ...
Please let me know..
Great
Does centre of symmetry present in Fisher projection?
Thank you mam...
Mam very nicely explain.
Mam pls explain,enatiopure
Theeek hai madam jii
Mam u r just best 😃...
Thank you ma'am!!!
Mam why u r not uploading vdos in a regular manner.. We r eagerly waiting for ur vdos mam...
Ma'am epimers and anomers dono m ek hi carbon centre ki configuration diff h toh pta kse chalga kya diff h dono me
At time 28:52 a & c are not isomer so they are not constitutional isomer
Ma'am ek confusion hai CH3 wale example me pos to mil rha tha then vo to optical inactive hoga
Please clear my doubt 🙏🙏
Thank you ma'am.
Great work
Thank you very much mam
What about Pro R and pro s
at 22:19 in that compound there is COS present or not
Thank you mam....🙏
44:31 pe pos kaise ho skta h mam ?
Why Diastereomers are Anisometric?
Please mam give answer
Very nice video mam thank you
Thank you so much mam
Plz plz plz make a vedio on concept of stereogenicity, chirotopicity, and pseudoasymmetry.
Thanks mam.
thank you mam❤️
Mam, what is homomers?
So nice mam😊
Thanks you so much mam
Mam can you explain that plane light ki direction ko kese clockwise or anticlockwise rotatr kiya..
Mam aapne ek galat pdya hai...meso compound me aapne btaya hai ki bsss pos hii hona chahiye.......
Lekin sahi ye hai ki koi ek hona chahiye pos ,cos ,Aaos meso compound hone k lyyyyy
Didi... Is cis/ trans diastereoisomers r called pi-diastereoismers..?
Hlo mam . Ap please white board and marker la lo plzz... us sa acha smj aya ga is sa thoda clear ni dikhta. Plzzz nd thnkwee so muvh apki vedios awsmm han mam.
Mam 22:47 mei 4th question mei COS hoga to optically inactive
Thank u mam
thanks
Thnx
Thanks maam🙏🙏🙏🙏
29:06 a b constitutional hai but a c isomers hi nahi he .. please check
ap achhe lgte hoo ma'am. love u soo much
Api Zimmerman taxler model p vedioo bnayy...plz exams ho ry mry h plzzz
Mam no. Stereoisomer kaise nikalte h ye to bataye niii
Mam , please re explain anomeric carbon????
@22:12but mm COS present h
Kindly upload English version videos
Mam anomers sirf haworth mein hi dekhte hai kiya
Very nice please used mike
44:31 there is cos how come they r optically active
Mam o connectivity kaise deside karte he
Steriospefic and sterioselective pr bhi plz video bna do
didi, video ki 22.04 min par dikhaia geya molecule mai COS (in the middle of the vertical bond) par hai toh!
It is in Fischer projection so cos can't be predicted in this projection
Mast
I'm doctor so l will help you
Do you in rush?
