This video made me understand the D/L configuration accurately

Jazakallah Khair, .. Ek Itna Major Topic 2 minute me samjha dia.. So thank you.. Kal mera exam hai and it really helped Alhamdulillah. .. ❤

[@hemvatiaditya2045]

Short and concept clear vidio...thank uu very much sir ji..🙏🏻🙏🏻 god bless uu

[@atpstarkota]

Most welcome ✌🏻

[@kimseokjin4752]

thank you sir this is the first video which gave me exactly what i wanted instead of wasting my time

[@mandiramaji794]

Excellent👍👏😆!!!!!

[@anuragrajpurohit5265]

And please explain about "+" and "-" notation too

[@nishantjangra5386]

If a compound rotates plane polarised light in left direction it is devoted by leavorotatary and '-`and if it rotates in right it is dextro and denoted as +

[@py_yogesh_1435]

Does that mean + and d or the same?

[@nishantjangra5386]

@@py_yogesh_1435 no '+'and'd'is not the same thing
'+'indicates dextrorotatory compound and 'd'incates a similar configuration to d glyceraldehyde

[@py_yogesh_1435]

@@nishantjangra5386 Do u mean that we can't give the + or - notation by simply Seeing the Structure? Please give me the right explanation

[@tranquil1021]

See mate , let me explain ,
I also find same kind of confusion in this topic .But after VK sir my eyes opened .
small d and small l represent drextro- rotatory and levo rotatory.This is related with optical activity .If the PPL is turned towards right then its d or if it is turned left then its l .d is also represented as + , l is also represented as -
But this is D , L (capital D and capital L )which has nothing to do with optical activity .If OH group of last chiral carbon is on right side , it is called D form .If it is on left side it is called L form .
The optical activity of Carbohydrate (d or l ) is independent of D or L .
Although the carbohydrate is optically active as it hs chiral carbon

[@abhijeetmehta93]

Thank you sir... I got my concepts crystal clear

Sir, how can we convert Fischer projection of multiple chiral carbon to wedge and dash?

Lekin sir hydrogen ka Jo bond hai glyceraldehyde mai use back side me krne baad toh hydroxy group left Mai Aa jayega....

[@sarthakshukla7217]

seedhi baat no bakwass !!!!!
thanks sir 🙏🙏🙏

[@palshah2463]

Great content 👌🏽👌🏽

[@saivenkatpokala8137]

Excellent

[@snehaa2165]

Thankyou sir ji

[@nishantkumar6924]

Sir lowest chiral carbon should be second one(closer to aldehyde group because aldehyde is given priority over alcohol in iupac naming)..... PLEASE REPLY ANYONE

[@mallaramkumar2731]

i too have the same doubt pls any one reply

[@rajaryanvishwakarma8915]

Uhm if you haven't got it cleared, it's the last chiral carbon actually that can be said as the farthest chiral carbon acc to iupac nomenclature

[@prabhatmishra1194]

Sir is wrong
It should be highest chiral carbon

[@atharvashile1196]

Me too have same doubt

[@Anurag9344-q1i]

​@@prabhatmishra1194he meant to say lowest in terms of height i.e The bottom carbon .

[@Fyi5700]

Your videos r just excellent!! Keep making them

[@shannu_forever]

Thanks sir

[@knowledgewithfunmood4458]

Thank u so mach sir

[@nishattahsin1158]

Sir.. what does lowest chiral carbon mean?

[@kunalsingh6961]

According to iupac numbering , find out the lowest carbon which is chiral .

[@Roguecanvas]

Carbon chain me sab saii lowest jo haii..

[@lokendrapatel_01]

Why do not assumed CHO NEXT CARBON

[@sahilsinha3566]

Kitte video dekha smj ji nhi aa rha tha
But now it's clear
Tqssss soo much 😘😁🙏🏻 love you sir.....

[@aizakhan7541]

Sir ,why OH group is at doted position ,in general H is at doted position

[@sahilatri5927]

2:53 pe H to dash pr nahi ha usko rotate ni krna padega pehle?

[@jagdishoswal7704]

What if Oh and Nh2 are not present on right and left (horizontal)
Instead they are on vertical line

[@biologyexplorer2721]

You are the best organic teacher in world .What was your marks in chemistry in IIT as you are IIT Roorkee alumni.

[@royalhussain6285]

In wedge structure, if OH is not on dashed bond , then how to look for DL??

[@gamechanger1785]

Thanks

[@harsithc9441]

sir what happens when molcule is rotated 180* when aldehyde comes down then which is lower most chiral carbon

[@mehnazashabir125]

[@srivastavtamannah02]

Sir can i say that D and L are mirror image of each other in any such compound??

[@hussainshaik6985]

yes bro

[@MujisimFathimaMohammad]

d and l ...anyone explain

[@aparnajhariya3495]

Dextro and leavo

[@allgamesyt2151]

​@@aparnajhariya3495No for dextro and laevo we use + and -, D is for the compounds which are derived the glyceraldehyde in which OH is on right side while L is used for those who are derived from the glyceraldehyde in which OH is on the left side they have no relation with the optical dextro or laevo

[@sohammehta5369]

Sir aapne conformation in hexane nhi padhai

[@sunilkhillare9551]

What is meaning of D-(-) and L-(+)

[@roshankumar4989]

Sir we better understand when you teach on the front of slide. 💖💞💕 please can you teach on the front of slides 🙏🌹🙏🌹🙏

sir can I contact u in whatsapp??

[@theporcupine9993]

Why put the titel in english, if it's in Indian ?

[@nawnitsinha9332]

India is the 2nd country in terms of speaking English!!...so we are not surprised to see the thumbnail in English language....we can understand both Hindi & English!!😎😎😎😎😎
