Michael addition reaction
This lecture describes Michael addition reaction of alpha beta unsaturated aldehydes or ketones. A comparison of 1,2 (direct)and 1,4 addition (conjugate ) is also made. Conditions to that favour a particular addition are also discussed. At the end of the lecture, few examples have been discussed.

Markovnikov's rule: misquoted or misunderstood?
มุมมอง 13Kปีที่แล้ว
This lecture describes the Markovnikov's rule operated in the electrophilic addition reaction of unsymmetrical reagent. The rule has been misquoted in many textbooks and hence misunderstood by learners. #markovnikov rule#
Is Methane (CH4) really tetrahedral?
มุมมอง 1.3Kปีที่แล้ว
This lecture describes how chemists came to know that methane has a tetrahedral structure. The lecture takes you through various possible structures one can expect for methane and how they were refuted based on experimental data and why only tetrahedral structure is the only viable choice for methane. #tetrahedral structure of methane#

Baeyer Villiger Oxidation/ Rearrangement
มุมมอง 3.3Kปีที่แล้ว
The transformation of ketones into esters and cyclic ketones into lactones by peroxyacids is called Baeyer-Villiger oxidation or Rearrangement. In case of unsymmetrical ketones, different groups migrate at different rates depending on their ability to stabilize the transition state. The migrating group migrates with retention of configuration.
Hell-Volhard-Zelinsky Reaction
มุมมอง 1.9Kปีที่แล้ว
This reaction is given by carboxylic acids having alpha hydrogen. The acid on treatment with PX3 (formed from Red P & X2) forms acyl bromide, which undergoes tautomerization and reacts with elemental halogen to form alpha haloacyl halide. This compound can undergo many reactions such as, (a) it can be hydrolyzed to form alpha halo carboxylic acid. (b) it can be converted to other acid derivativ...
Clemmensen Reduction of Aldehydes & Ketones

The Reduction of carbonyl group of aldehydes and ketones to methylene group on refluxing with hydrochloric acid containing amalgamated zinc. That is zinc surface treated with mercury.
Enamine: Formation, properties and Reactivity
มุมมอง 2Kปีที่แล้ว
This lecture describes the formation of enamines by reaction of carbonyls with secondary amines. The mechanism is similar to Imine formation except that last deprotonation occurs at carbon since iminium ion doesn't contain any hydrogen attached to nitrogen. Enamines beta carbon is more basic than its nitrogen due to pi donation by nitrogen lone pair into alkene pi bond. Enamine nitrogen is less...
Wolff-Kishner reduction
มุมมอง 2Kปีที่แล้ว
Reduction of carbonyl group of aldehydes and ketones to methylene group by heating their hydrazones or semi-carbazones in the presence of a strong base such as KOH or t-BuOK in ethylene glycol or DMSO solvent. Semi-carbazones are first hydrolyzed to hydrazones before reduction is attempted.

Much more helpful ❤❤❤❤ ... Allah blesses on u sir. Amen .
Thank you so much for your lesson
Obliged....🙂
Asalamualikum sir.. U hardwork and dedication behind these lectures... Is so appreciable.. I am. Confused why the people are taking lectures from. Unprofessional chemistry teachers.... Learning from u sir.. How. To. Understand actual ethics of this precious subject Now. a days people have made markets of this subject but u r the one who. Is providing new life to this subject ... These lectures r very much different and are rare to find on u tube .this is the way how to teach organic chemistry....@ Dr Niyaz sir...❤ Regards .. Idrees Riyaz.
Explanation is too good 👍
thank you so much😊😊😊
Most Welcome. Share if you like this.

It is not your voice sir G.
Offcourse not mine, I had some problem recording voice, so had to use alternative.
Thnku
Sir please make video on stereochemistry of hydrogenation of alkenes reactions
Will do.
Gr8 initiative sir......
Very nice lecture...
Thanks and welcome
i think your original voice is much better and has a coherence
🙌🙌🙌
Nice
Asalamualikum sir ji... This is totally unbelievable and specfic lecture.. On u tube... This is how the organic chemistry is to be taught... We r eagerly waiting for ur other videos on organic chemistry sir.. Hope so u will.. By help of ur videos we people have understanded these topics with clearity as u had provided the best version of understanding organic chemistry.. Live long sir ji... Amen... Regards idrees Riyaz
❤️❤️❤️
Nicely explained...
Glad it was helpful!
Waiting for more ❤️
I am on it.
