[@ramavtarverma8454]

Ma’am you are an excellent teacher. I’m a retired chemistry teacher (70-yr old )

[@JChemistry]

Thank you so much for the encouraging words, Sir! It means a lot to me.

[@harshad6474]

Ky proof hai ?

[@anushaalugoju740]

😂​@@JChemistry❤❤

[@SapnaBSP--]

At 21:42 mins, the molecule has centre of symmetry cos; so it will be an optically inactive molecule

[@swatisharma4956]

Aapne constitutional isomer mein bromo gp lagaya to show different connectivity wrt to cis/trans dichloroalkene. Isomers must have same molecular formula

[@Tsss5168]

You have extremely great quality of teaching.. I seriously feel blessed that i found your video. Thanku very mch.. God bless u.

[@sridharaadhi1423]

Past three days i'm watching ur videos about Stereo chemistry,very nice explanation 🙏,thank god i know hindi fluently😊,keep rocking mam💥

[@vismiforever8357]

Very happy by seeing subscribers increment..... I subscribe when there is only 7k....happy to follow your lectures

[@JChemistry]

Glad to know that :)

[@anumgul6538]

JAZAKILLAH ALLAH apko khush rakhe bhot ❤❤❤❤❤❤❤

didi your explanation muje bahot acha laga ...want more video (ORGANIC MAINLY)

[@user-qz4yv4nj5m]

Very nice ma'am

[@deebikabaskar2067]

Mam, excellent work. I don't know hindi but as you write everything that you speak I could understand. Very dedicated

[@D_zone_18]

need to feel ashamed... You are a Indian

[@meghdeepmaity3558]

very simple method of teaching without any complexity ....great mam

[@abhilipsasahoo770]

at 28:52 min. a and c are not at all isomers rather 'c' should be geminal dichloride.

[@beastabhi001]

22:10 but these have centre of symmetry. Then why they are optically active.

[@RajeevRanjan-ud4lw]

Your explanation is so beautiful and teaching style is wonderful ma'am....🙏🙏

[@abhimanyumaharana2509]

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...

[@JChemistry]

Yes definitely Meso Compounds have COS as well as POS ....and they are optically inactive

[@nehahena1501]

Thnku so much jyoti mam.... Its suprb explanation... Brilliant...mujhe apke videos s hi stereo smjh aayi

[@mayankwasnikiitkgp3430]

I am watching it for JEE ADVANCED,,It is helpful 😄,Thanks!Alot Didi

[@ZahidHussain-fo3hp]

mam aap bahur acche se samjhati hai ...thanks alot

[@easytolearnhere5212]

At 20:10 min. Br and Cl are different group how can molecules be constitutional isomers?

[@easytolearnhere5212]

Sorry at 28:50

[@jeevanchouhan7727]

Yeah same question

[@akibmustahid6467]

They are different compounds, watch the organic chemistry tutor

[@mittupatel582]

Yes same question ⁉️

[@pushpakhare5053]

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

[@Rohan-dl2rm]

Thank you mam so much..your teaching technique is unique and very helpful,,,😍😍🥰🥰

[@pawanjanimehta7091]

Thanku di..u solved lot's of my problem this topic..ur teaching style mind blowing..I like it.. where are you from 🙏

[@sarveshgarg72]

Mam u r fantastic... U r superb 👍👍🎊🎊

[@kusumshibaranjanibohidar5996]

You're the best. God bless you 🙏😭❤❤

[@sumanthgs8297]

At 22:12 the structure has COS then it must be Optically Inactive, right???

[@rukhsarmughal9459]

Yes I also noticed .... 🤔🤔🤔

[@vanibabu6574]

Yes it is optically inactive....it has COS

[@satyamkhedkar7742]

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

[@Bankerav-nn8jh]

@@satyamkhedkar7742 COS ka kya?

[@shashwat3653]

Yup u r right

[@piyalidas7837]

At 37.04 min,the central carbon containing OH on dash bond is chiral as per your part 4 video you said...!

[@meenakshisingh4712]

Exactly my point!

[@beastabhi001]

How it's chiral according to you?

[@pankajsharma-ur7nm]

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

[@radheshyam-oo8hg]

mam yu are really great teacher in the field of chemistry

[@surendrabahetiaryabhattacl1929]

Last example in optical activity is active, how? Bcoz there is COS is present

[@han-rw1bg]

At 37:25 the middle carbon from which POS is passing through. Can we say it pseudosymmetric or not?

[@shashanktripathi8849]

Yes pseudoasymmetric

[@maiyadhruvx544]

yes

[@SërïòuSattitúde]

Mam anti conformation of meso tartaric acid ka (i) present hai optically inactivehoga according to 3 codition for optically active

[@trinapodder3992]

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???

[@yogeshmali8473]

Thanks a lot mam....way u teaching awesome 🙏

[@reemasahu5051]

You are really great mam.....

[@abcdchemistryclasses8313]

at 22:12 molecules have centre of symmetry but mam you are telling optically Active

[@indraneehazarika2914]

No the molecule doesn't have centre of symmetry.(draw in Sawhorse)

[@gauravsingh-fe3kw]

Fisher projection doesn't have cos .just draw sawhorse of it

[@ishitarajgaur5991]

@@gauravsingh-fe3kw we can't draw all the projection in the exam

[@pritykarmakar4937]

Thank you so much mam 🙏🙏🙏🙏

[@subhajitgoswami7336]

Plz plz plz make a vedio on concept of stereogenicity, chirotopicity, and pseudoasymmetry.

[@iqrarhussain9706]

Great

[@rishusingh3986]

thanks mam

[@MBA_wale]

Thank you mam 🙂

[@santoshkumaryadav3616]

Thank you so much mam for making this video 🙏🙏🙏

[@rimapatel1597]

At time 28:52 a & c are not isomer so they are not constitutional isomer

[@pratikshasalave5524]

Thanx di

[@yasaswinisaladi8001]

Awesome made my preparation easy🙏

[@ethicalhackingfact5139]

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.

[@dattubuchkul7730]

Mam very nicely explain.

[@dsoumya671]

Optically active mai jo last example tha usme to COS present hai , to optically inactive hona cahiya ... Please let me know..

[@chemistrywidbikash6934]

Mam why u r not uploading vdos in a regular manner.. We r eagerly waiting for ur vdos mam...

[@pallavibhosale6001]

Thanku so much mam

[@ishitarajgaur5991]

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 ??????????????

[@raviprajapati431]

Yes ... Ye molecule inactive hona chahia ....

Theeek hai madam jii

[@lokeshjatav5166]

Very nice video mam thank you

[@lokeshjatav5166]

Thank you so much mam

[@sharungarg2850]

At 35:31 though it doesn't have POS but it does have cos so how can we say it to be opticaly active?

[@parthshah3943]

It doesn't have cos, coz it's check from center, they are not at pera position. So it doesn't have cos

[@athirajoseph8537]

Great work

[@chiragdagar7938]

Thnku mam ❣️

[@rekharikhari8849]

Mam can you explain that plane light ki direction ko kese clockwise or anticlockwise rotatr kiya..

[@sakibvakaliya4009]

Why Diastereomers are Anisometric? Please mam give answer

[@gauravsingh-fe3kw]

Does centre of symmetry present in Fisher projection?

[@chemday8509]

Mam u r just best 😃...

[@priyankasogarwal8750]

Ma'am epimers and anomers dono m ek hi carbon centre ki configuration diff h toh pta kse chalga kya diff h dono me

[@IITian729]

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

[@umeshrawat9038]

at 22:19 in that compound there is COS present or not

[@chemistrylover7940]

Api Zimmerman taxler model p vedioo bnayy...plz exams ho ry mry h plzzz

[@avishkasrivastava100]

Ma'am ek confusion hai CH3 wale example me pos to mil rha tha then vo to optical inactive hoga Please clear my doubt 🙏🙏

[@ninjacooks5828]

Mam 22:47 mei 4th question mei COS hoga to optically inactive

[@nanotechnology107]

Mam , please re explain anomeric carbon????

[@biologyworldbyvaishaligaik3351]

Very nice please used mike

[@goumenbaite5742]

44:31 there is cos how come they r optically active

[@jagritichoudhary6924]

Mam no. Stereoisomer kaise nikalte h ye to bataye niii

[@udayshankar3817]

hello maim ..... so far it was very good but here at 35:10 if you rotate the molecule for 180 degree will get the same molecule; since the one Me point out the plane will go inside and the one which is pointing inside will go down, you can check in chemBio draw 3D it shows same then the molecule will become meso and the same way the next will not be a meso plz do reply; If I'm wrong.

[@anjalisharma1895]

mam said that only inplane rotation is allowed ..and also it has pos

[@rekhakailassonune1262]

Mam o connectivity kaise deside karte he

[@nidhakhan7608]

maam no of stereomers nikalna b sikhaye?

[@pragyanborah2254]

didi, video ki 22.04 min par dikhaia geya molecule mai COS (in the middle of the vertical bond) par hai toh!

[@Ganirage]

It is in Fischer projection so cos can't be predicted in this projection
