RWLD is the best trick sis..it's working too good....keep teaching us with ur easy tricks Di..❤️
Please have a contact with me if u have good knowledge of chemistry

i hated the organic chemistry but your way of teaching makes it easier. thanks for J CHEMISTRY
I'm watching this just an hour before quiz, now this concept is quite clear. Thanks a lot!!
"RWLD" Nice trick m
I'll never forget
Nice command on Organic chemistry..Keep it up..
Thank u mam specially for RWLD trick 😊😊😊
Ma'am your way of teaching makes organic chemistry so interesting!
Thank you so much.
Mam can u take the same in English....
Very nice mam
In last example mam why not R group goes down and allylic alcohol goes up.. If it happen product will be change i think plz explain.. 🙏
Yes my also same question. Pls can u xplain
Yes same question
Yes i also got this problem plzz explain....
Your chain has to be a zig zag chain. Except the alkyne portion which is straight. When it's reduced to alkene, then whole chain becomes zig zag. Now if u start from the left end of molecule and move towards right U'll note that the allylic C (on the left of triple bond) is up in zig zag chain. So automatically the alkene C attached to it will be down in zig zag chain. Then next alkene C will again be up in the zigzag chain. And now since it is E alkene, the C having OH with it will have to be down in the zigzag chain to make E alkene. If it were Z alkene then this C would remain up in the chain like the previous alkene carbon, so that this double bond becomes Z.
@@abhivyaktichauhan6960
Yes exactly my point is that if we follow the zigzag pattern of chain which is already given into the question we get the left carbon of alkyne dawn (not up) and in that manner the pri alcohol part goes dawn so if we check the str. we get it as wedged str not dashed one.....
If some one having more doubts on it you can check this question in june 2012 paper where the str. is given more clearly....
Please make videos on electrochemistry and thermodynamics formulas which should be essentials because we don't have enough time to study all the stuff of that chapters.
Good explanation,makes chemistry easy and simple thanks mam
Thankyou mam , aapke pdane ka trika bhoot hi aacha h ...sare concept clear ho jate h,,,,,, thanx once again 👍👍
It's just an awesome trick!!
You're too good ma'am. Keep helping our nation.
RWLD trick amazing.
Awesome best video mam
Thanku so much
Mam, at 28 min. What if i show the linked hydrogens in opposite directions to show trans as u have shown.
Mam..last bala example ke structure pe thoda doubt hai..app carruther ke 130 page ka (2.62) equation thoda dekh lijiye.. aur mereko confirm kijiye app ne wo trans alkene ka structure wrt OH group sahi draw ki hai ya nahi..
Dear Jyoti Your way of teaching is very impressive......You are doing great job..Keep it up...
Bahut achha padhati ho ma'am
Thank you so much mam 🙏🏼🙏🏼🙏🏼🙏🏼
Mam u tech very well this topic... thanks 😊
Kya bat h mam RwLD nic trick i m impress
Mam you really very best
Yasir from Kp Pakistan
Brilliant ma'am.👩🏫
Yes
Nice aap ache video bnate ho hme bhi aapki class mate Jo ab hmare teacher h aarti mam ne btaya tha ye chanal
Please convey my thanks to her 💚
In the last example, you have written the trans alkene which can be also written in another form where allylic alcohol will be on right side.so which configuration we should consider. Kindly clear my confusion ma'am..
Yes mam..
Classy explanation.I am damn sure that you will get a call from Unacademy very soon.
I got a call from unacademy today itself !
Thanks for the appreciation :)
@@JChemistry what's ur gate rank?
In last example, there is reduction of alkyne into trans alkene but another alkene present into compound also reduced into alkane .....I did these type chemistry in lab ....In my compound both nitro n alkene present n both are reduced by LiAlH4
Ma'am 🙏🏻 kya trans wale example mai epoxy linkage str ki left right kahe bhe laga sakte hai ya only left side lagana hai
Red(right ) allyilic -OHwall ( above the plane ) mean laal deewar ( below the plane )
thank you, ma'am, for brilliant explaining
Amazing way of explaining the concepts.. you made it very easy for everyone... Thanks mam. ❤️
Left_wedge
Right_dash
For +DET both
This is really helpful.
Thank you very much.
Madam last example me OH right side bhi ho sakata he to left consider karane ka koi specific reason he kya
Incredible teacher
Thank you so much this much information will be very helpful from exam point of view..
Nice mam RWLD nice trick to learn
Mam plz make vedios for x-ray differection spectroscopy
mam 2k soon 👍👍
thanx mam .great work n help . make more video
Maam aap bahut jyada intelligent
you explained this too well mam thanks
In the last question, trans alkene two types k bn rhe and so wedg and dash dono types k product bn rhe.ma'am pls explain ma'am pls.
Wedge product should be major
Same doubt... My answer is also wedge
Both answers are correct according to the positions of R group and alcohol... We should answer according to the options given in the paper.
k yesss
@@aishwaryachauhan349 mine too
If there is -I effect operating on wittig reagent but the reaction occurs at negative temperature, then Trans product is favoured or Cis...??
Mam plz also make videos on assymtric catalysis like u make on mcpba and sharpless epoxidation ...similary make video on hydrogenation via assymtric hydrogenation ...and also other rxns too
Ma'am last question was asked in June 2012 and answer is wedge prduct.ma'am the E alkene Jo aapne draw kiya hai ar Jo maene draw kiya hai wo different hai issliye jo mera ans hai wo wedge product hai.
You are right....
Yes you are right
You are really good teacher mam thanku so much.
Thanks man you r really superbbb
Please upload a video on cram's rule on conceptual based and trick based
Mam
Rotation of allylic alcohol, clock wise or anti clock wise
Wooow very nice superb 😍
Plz make videos on sterochemitry with basic
I have already uploaded
ruclips.net/p/PLYXnZUqtB3K_Z1y56fUgFh0wl9lHclY2P
Mam very thanku for reagents
Mam please upload shi& katsuki .jackson rearrangment with steriochemistry. Because I only follow your chanel. I Understand ur videos clearly than other
Mam I have problem that -If we change alkene of last example then wedge form is obtained
Yes for the last one wedge form is obtained if we change the alkene . Ma'am can you just explain this once.
Mam iske saath Payne rearrangement bhi aata hai.. Saath mein
can you please tell what does "=" symbol indicates in the sharpless epoxidation reaction means. I saw it in a book by "mundy"
Very nice tricks
Ma'am last example me LiAlH4 reduction ke baad 2 tras product mil sakate hai... To rotate karke RWLD kaise apply kare..plz reply
Superb mam nice tricks
Please make video a reagent of lithium Isopropyl amine(LDA)
Mam coordination chemistry k videos upload kr do plzzz
Please mam!! Really needed.
Nice vedio thanks mam.
Happy durga saptami from me from kolkata. I wish that you get all success in your life.
Thank you for the wishes :)
Wish you the same 🌺
Maim 3 membered fulvene aromatic hoga ya anti non aromatic
Sharpless Asymmetric epoxidation Exmple ke sath mechanism solve krke Dona mam
Best mammm
Love from pakistan
Mam ye wrong he becoz + DET he toh RDLW hota he.plz mam mene claydon se refernce liya he aap ek bar check kr lena.
I will wait for your reply
Thanks mam so simple trick.... Awesome...
Thank Q so much😘❤️
mam second last question mein phosphene to hai hi nhi
mam, epoxide me sesh or weig -OH side lagate ya uski opposite side par
22:50 where was the oxygen atom which was bonded bonded to cyclohexane? ....i didn't get madam?.....i don't know Hindi....i am from karnataka madam
MAHESHA MAHESHA K P ...its a trick to get the wittig reaction pdt without mechanism
Thank you sister.....
Does alkynes get reduced by LiAlH4?
U complete reagent chemistry
Namste mam, i have got 18 marks in IIT Jam 2019 (not qualified) for me
This reagent seems too difficult mam,
This reagent is important from CSIR-NET and GATE point of view Ayush ...you can leave it for now ...it won't be asked in any of the MSc entrance exams ..don't worry :)
Mam..can you daily upload videos for 2 reagents..plz
Nice trick
Madam your teaching and everything was good but please talk slowly we cannot understand your language quickly
Thank you very much mam
Very helpful trick
mam in last example if i form another trans product then oh comes on right side .... then final product become change .... mam then how we can choose which trans form we take ?
Try drawing other trans form and you'll realise that it's looking like trans but it's Z (cis)
Thank u mam
Better to rotate the question paper itself. Another small trick! :-D
Mind blowing
What is the configuration of -CH(me)OH ?
Please do explain in english it feels difficult to understand hindi sometimes
Suggest a best book for reagents
Thank u for trick
Thank u so much ma'am
How hard do you work
Extraordinary😍
Thank u so much mam😇
Mam 18. 13 how u remove Br??pllzz reply mr i have pprz
Thank-you mam🙂🙂🙂
Very Thanks mam
Houk model ke bare m Btna kuch
Mam rotation within the plan hi krna h??ya out of plane v kr skte h
Double bond is planar only ...I don't understand what do you mean by out of plane Rotation
Mam last example me trans alkene two types se ban sakte hai to major product kon sa Hoga ??? plz explain
I also have the same query....as other trans alkene leads to wedge epoxide
Waaw maam
How alkyne is reduced with LAH..... It reduces only isolated triple bonds...
