Just wanted to let you know that you are amazing and your videos are lifesavers, please do make more videos like such ❤️ from Canada
Thank you so much 🌺
Love from India :)
Pls tell me what is pilot atom
@@shreyagarg634 first atom which is out of the plane
THANK U DIMDIJI , MERE IIT KGP KE PROFESSORS SE BETTER PADHA DIYA AAPNE TOH!
Mam u r explaining so nicely..even this stereochemistry is...3d unit hard to understand..Mam.u r my...role model....i am following...ur rules...of chemistry...u r really.. efficient and nice ....teacher...that i have not seen in my last 20 years...
Mam u r great!👍
May God bless uh with whatever u want..
Tysm
Madam aap great ho ......Itne piyar se samjhati ho aur achhe se samjhati ho pura smjh aata h .....
Thank you so much
Awsm explanation. I have never seen teacher of chemistry like u.. God bless you
I know Im kinda randomly asking but do anyone know a good website to stream new tv shows online?
@Hayden Jeremy I use flixzone. Just google for it =)
@Marvin Rodney Definitely, I have been watching on flixzone for months myself :D

@Hayden Jeremy You are welcome :)
U r really professional teacher..just awesome 👌
Superb Explanation Ma'am 🙏🏼🙏🏼🙏🏼
simplified explanation ... thanks a lott madam
Great effort.. thanks you so much
Superb.... keep goinig
Video Created interest in stereochemistry and also easy to understand.
Need a teacher like u ma'am...God bless u❤
Thank u very much for your efforts to make us understand.
Great explanation. I enjoyed a lot👌
Thank You Ma'am 🙏🏼❤️
i really enjoy your lectures ma'am 👍
Really very informative lecture.......

Mam thanks for this....very helpful👌👌
Very impressive mam
Less time me best metter 👍👍👍
And I understood very well
Nice examination mam Thanku so much
Such me dear maam u very great talented not only teacher but great explainer with sweet voice of organic chemistry which make me easy to learn thank u maam 😊...love from Pakistan ...
Thank you mam... best explanation 💫💫📚
Thanku so much Mam👌👌
Very nice Explained 👌💙
Thank you Ma'am
Good morning mam . happy upcoming durga puja
Great

Very simple and understandable
Thank s madam garu
Awesome mam
Mam I'm from ICT Mumbai .......... Your lecture helps me alot
Mam you are really awesome 😘😘
Fabulous explanation maam
Thankuuu so mam great video
Thanks ma'am
amazing explanation ...though I am not from chemistry background . (I am a pharmacist ),, still I understand ur whole lecture ,, u r really talented BEAUTY WITH BRAIN … thanks a lot mam..
thank you ma"am
Good job Jyoti
dii.. you are just awesome.... app na jam k liye bhi coaching class kholdo.... bohot help hoggi... hum baccho ko...
You r going to teach group theory .. i want to learn form you .. you are teaching like a professional teachers .. thanks
awesome😍
Thanks again mam
good teaching
Mam there is no such requirement to place the lowest priority group on the dotted wedge in allenes to determine/designate them as R or S stereomers. Such a requirement arises in chiral centers attached to four different groups pointing in different direction. In allenes groups have fixed geometries in two different planes at the terminal carbons. This modified R and S nomenclature is applied to allenes with even no of double bonds as they are considered as extended/elongated tetrahedrons. Also, you can view the molecule from either end. The groups attached to the carbon from the viewing end get priority over the farther end while designating them as Ra or Sa.
You have very nicely taught
Thank u soo much mam
Thanks Mam
Thankyou mam you are really good
Thanks
Wonderful. One small qn
If stereo chemistry is not mentioned for Biphenyls and we are asked to find Configuration, how do we find?
Thanks ma'am 😊😊
Thanks ma'am 💐💐💐🙏🏻🙏🏻
I love chemistry mam thanks♥~♥~
Thank you mam💖
Thk hn🔥
Tqsm mam
Thankyou so much
Aj aap chemistry ka... Exam hai kya..?
Thanks mem ❤❤
Sister thanku ❤️
Thik he ji
At 28:10 cyclophanes for upper ring we write opposite config bcoz very simple,you rotate your finger towards clockwise now lift your hand with rotating only above your head then look at your finger it moves anticlockwise.Same here we have to look from lower ring side view.
👍👍
Very good explanation mam plz make a video on geometrical isomerism
Didi aapke expalen krene ka trika muje pasnd aa gya
Mam please make videos on which chapter you should cover from books like d nasipuri,clyden and others book..
Mast
👌👌👌👌👌👌👌
Thnkyou mam
thanks
Ma'am, your lectures are awesome,👍lekin app agar thik hai ka use thoda kam kar dengi tab aur achcha lagega.Thank you
Good
Bdw. ..great great great great...... (Infinity) video..
owsom hairs.....................
Ma'am I have a confusion. You said that the cumulene (in 6:10) has plane of symmetry. But ma'am, the extreme two carbon atoms contain different groups. So, will there be POS?
Mam ansa compds me jha Br and Cl lga h vo carbon no.3 kase h.smgh nhi aaya
👌❤️👍
❤❤
Ma'am is there any video on the R S nomenclature of epoxides?
I am facing few problems in that topic
Plz madam make a vedio syn/anti nomenclature for aldols. And E/Z descriptors for C=C, conjugated diene, triene, C=N and N=N systems. Plz plz plz make a vedio on above topics...
very very nice medam
Hello ma'am ,
Ma'am 31:51 pr aapne ek m numbering right hand s ki h, doosre m left hand s jbki hm apposite b toh skte th?
Is there any reason for this ?
