- Hello, Guys. In this Lecture we are going to explain all the important points, concepts and questions from Iodoform test.
This is the most powerful Lecture for jee advanced and AIIMS. Here, We will discuss this topic for Jee Advanced and AIIMS level.
First of all u need to understand the basic mechanism behind this reaction. In this reaction you treat a compound containing methyl carbonyl group with X2 and NaOH. Here NaOH is a strong base which extracts a proton from the alpha position i.e. the methyl group, thus producing an anion. This anionic group attacks the halogen molecule extracting X+. This leaves us with a compound with one alpha hydrogen replaced with a halogen atom. This same process repeates two more times. This produces a compound with all three alpha hydrogen atoms replaced with halide groups.
Now a new molecule of base NaOH attacks the electrophilic carbonyl carbon to replace the tri halide methyl anion. This anion extracts a proton from the carboxylic acid formed to generate a haloform molecule with by product as the carboxylate anion.
This complete reaction is known as haloform reaction.
The rate determining step in this reaction is the formation of a stable alpha carbanion. So stability of this carbanion enhances the forward reaction.
Hope this helps :) . Feel free to ask any further doubts in comment section.

#IodoformTest #Exceptions #IITianExplains
He is again here to deliver the best content on TH-cam. Iron(Fe)Man of Chemistry.
Sir aap plz aise hi exceptions ke uper videos banate rehna......they are extremely helpful.......koi coaching institute ka teacher itna deeply nahi padhata h jitna aap......fan ho gaye aapke🔥🔥
sir u truly deserve 1M views on every videos....
i guess more and more people get to know abt ur awesome videos...
and ur channel may grow bigger and better...
BEST WISHES❤️
Sir, I am JEE Advanced student from Resonance, Last year my rank in advance was 11209, i am appearing this time once again.
Sir, Do you know dushyant kumar chemistry channel ?
He is teaching absolutely wrong about Tollens and iodoform tests according to my resonance lecture notes and your channel as well..........I asked him on their channel and mistakes......He blocked me even without replying....... They are really Axxxhxxle teachers.
Thanks for clarification on this topic.
Love from Resonance Kota.
He blocked me as well for same questions, I hate him. he is ridiculous.
I also noticed the same and that's not a good thing, his organic chem. Lectures aren't much beneficial..... btw we should respect every teacher who is providing free education 😅....
Broooo, No-one is going to eat that Shit 💩 on the name of free education.
Whenever I see his content. - me. " ye toohhh tattiiii hai.." 💩
But he teaches inorganic good.
@@tanmaysarkar8384 nope , he is also very good, you can't judge a teacher by his 2-4 mistakes, his revision videos are good 👍
Must for JEE.......
1. HCV
2.Cengage
3.MKA sir.....
😍😍🙏🙏🙏🙏🙏🙏
Agreed
Lol 😂
Not cengage
Correction required
For me:
Must for JEE
1.cleared concepts + thinking in physics
2.deep knowledge and application in chemistry
3. Practice and intelligence in maths 🙂
No jee oriented books required

waah sir aap unacademy aur apne youtube channel dono itne acche se manage kr lete ho aur yha hamse 3 subject bhi manage nhi ho paa rhe 😂😂
Same here
Today's lecture is an absolute beauty,
No chain pulling....😎
.🔥🔥
Now that is called a Boom Boom 💪💥 concept from guruji only for jee advance there is no mains level for guruji 😎🌠
Thanks for great video!
Please consider tollen reagent exception for a video.
Thank you
Guruji 🙏🙏SN2 v/s SNAE v/s Addition par bhi ek video bana dijiye bahut dikkat hota hai pahchane main ki kahan par kya hoga
Sir plz biomolecules and polymers ki vedio bnado sir plz... aapne unacademy pr karaya hua hai..pr fir bhi plz meri request pr youtube pr bhi bnado sir plz.....plzz sirrr
Sir, really bahut maza aaya kuch naya jaan kr
Aap pls biomolecules aur polymers pr bhi videos bana dijiye
Very very much useful...
Thanks a lot sir..

Yes sir CSIR net ka chalu kijiye na apka teaching style osm h sir
Plz sir
15:20
Isme phir OTf leave hone ke baad jo product ka methyl-ketonic part hoga, woh dedega iodoform?
(Provided I2/OH- is in excess.)
Sir plsss can u upload videos on full isomerism topic
22:00 Oh my god😵😵😵👍👍
Thanks a lot sir , was really waiting for tests of organic compound , Please complete all the organic tests in jee advanced.
🙏🙏🙏
😊😊😊
Thanks sir for unique lec please next lec CFT in coordination comp please sir
Made notes now,I was travelling that's why it took time😅
Awesome lecture sir, pure gold on TH-cam 💓
bronze silver toh Kahi bhi mil Jata but Gold Aapke pas hi h💝
The video that I have been waiting for and wow sir uploaded it thank you sir ji , you are really very good at explaining and making it very easy for us .
Thank you sir ❤️💕
Sir one request please make videos on Michael addition🙏
Sir ji chemistry in everyday life kab hoga class 12th ka ???????😥😥😥😥😥😥😥
Sir please help by making video for jee main and also help us for boards on this topic
Sir pl also make a video regarding reagents like jones reagent ... including some others jo aapne reagent waali videos me include nhi kiye hue
Really awesome teaching !!!! Thank you sir
MKA sir is best for Chemistry ,,,his way of explanation is just Awesome ... his channel is the inner core part of the TH-cam ,,,,
and to be frank ,,,, let it be here only ,,,
Sir mast padhaya thanks
Maza aagaya sirji
Mka sir on fire , u sir are unstoppable from providing true and helpful knowledge to students like me ,........... THANXX..., SIRR......🙏🙏🙏🙏🙏🙏🙏🙏 #JEEADV
So nice video
I was waiting for it.😊
Thanks you gru Ji....🙌
Boom boom concept 💪💪👊
Don't you feel that the H removed for being acidic should not be very relavent in few cases as the base is in excess so more base can come up and take away the alpha H that gives iodoform..like ethanol can also give iodoform..
Boom boom 💥🔥🔥🔥😎😎😎
Mast h bhaiya....
Sir i have a doubt...if we have basic medium then why not after abstracting the most acidic hydrogen,the base goes to abstract the second most acidic hydrogen and form iodoform.
GURUJI YOU ARE GREAT........❣
Yeah
Greatest
Plzzz teach isomerism in coordination compounds😊
first VIEW .. OSSM VIDEO SIR JI
You are just mind blowing guru
Thank you 🙏
Dil khush ho gya sir ye video dekh kr..😀
Sir please make a playlist chapterwise
In that c 14 question the c14 containing ring is attached to 2 electron withdrawing sites so it should go out as iodoform even though its bond dissociation enthalpy is more
Boom boom explanation of idoform test , Thank you so much sir.
Mind got blown away now sir, I am totally in awe of you sir 🔥 What a lecture
I have always thought that only (CH3-C=O)- and (CH3-CH-OH)- can give this test even though I knew the mechanism still i was dumbstruck when I solved your examples
Thanks a lot sir, ❤️
Best content on iodoform. Thank u sir 🔥🙏
Done
Thank you guruji
Definitely one of the best chemistry in this field
Sir plz make viedo on named reactions plzzzzzzzzzzz sir u teaching is very nice and very specially for advance plzzzzzzzzz sir
Sir you were asking which part of video you liked the most, I would ask anyone who is watching this that which part of the video one doesn't like, as not a single minute waisted and gain so much knowledge thank you🌹.
sir. Can you Show any one archive question where this exception case has been asked? Please I just want to check which type of these can be asked?
ZAHAR CLEAR HUA AAJ SIR THANK YOU SIR FOR QUALITY EDUCATION FOR US AND PLZ BRING MORE SESSION ON THIS TOPIC
Sir, but in last example I have a doubt that even in very small amount iodoform is possible ??? Because as you said for precipitation as a driving force for reactions, is it possible?
Sir your class so amazing
Keep watching
Best ...Awesome and Quality Content ..
Defines why you are an iitian 👍😁😁
Best iodoform lecture ever🔥🔥🔥🔥🔥🔥🔥🔥🔥
Thanks Sir 😊😊😊😊
Really great explain sir 🙂🙂🙂🙂
Chemistry is nothing with out uuu sirr 😘😘😘
sir why in 17:54 oh- didnt attack the other c=o carbon to open the ring , it seems more electropositive than the top carbon c=o
very nice session sir. your energy is infectious. concept crystal clear now, thank you sir
16:05 ispe c2h5oh jo leave kiya wo to dedega iodoform ...?
never
Sir in the last question, after one hydrogen gets extracted, the chain will have a negatively charged electron cloud hence even if we have methyl group beside a ketone, OH- attack is very less probable.
Is my reasoning correct?
Please make a video on different rearrangements in organic chemistry
Amazing lecture sirji
Jai Ho Guruji...
Very op content sir thanku so much 👍👍👍
Badhiya sir bahut Maja aaya
Super sir g
Just wow!!!
Sir CH3COCX3 me dobara acid base kyu nhi hota OH- ke attack se🤔🤔🤔🤔🤔
Because-CX3 is an excellent leaving group
@@IITianexplains thanks sir I am very confused and you helped me a lot sir mka बाबा की jay😊💛
Sir please make a vedio on strength of neucleophile and base
Sir at 22:07 will the nitric acid from oxidise the CHI3 which is formed in the reaction along with it? Sir plzzz reply!!
Nope, it required elevated temperature.
Thank you sir!!
9:47 woh jo OC2H5 bana woh toh iodoform deta hi hai na
Sooper dooper mka sir
Thank you so much sir. Your vedio is very valuable. Plz sir make vedio on chromatography and some imp questions. Plz sir this is very important for bhu msc entrance
MKA GURUJI BOOTIPHOOL......THNKW SIR
Aap jaisi chemistry shyad koi itne interesting trike se padha paye
Sir, ethyl acetoacetic ester mein aapne ester wale carbonyl pe attack kyu karwaya? Dusra wala carbonyl better E+ hoga since it doesn't have resonance.
Because system OC2H5 ko leave krwa kar, immediately system ki entropy increase krwa Lega.
Thank you sir
@@IITianexplains but other carbon is much more electrophilic...
Sir i am your plus but still i am watching ,🙏🙏🙏♥️♥️
Oh man i totally love his energy
Yoo🤘🏻
Is it just me who thinks that some places he sounds exactly like technical guruji.. 25:00
Sir Ispe to aap pehle bhi lecture de chuke h
Fir kyun laye
