Carboxylic Acid Part 6 : Acid Derivatives
Very clear explanation sir.. thankyou so much 🥰
Thank you so much sir
Do quinones react like this too?
But sir that product is not coming in solid it is coming oily what should be done to make it solid
The heating of three components together at 90 degree gives yellow solid as product. In last week, we have carried out this synthesis. Roughly, yellow solid start to accumulate in flask after 45 to 50 minutes. So, I would suggest, plz heat properly for 1 hours.
Best explanation
Sir plz explain in Beckmann rearrangement Benzophenone to oxime to Benzanilide
It is very easy to understand it sir....Thank you soooo much❤🎉
Jai Hind Sir
Why it is stand for 2 hours??
thank you,it was very helpful.
nice sir g🥰
sir , is beta cleavage always heterolytic ?
Sir please ek video Mass spectrometry of carboxylic acids and ester py bhi bnadein
Ok...I will
This video is very helpful 🤗🤗 Thank you sir.
Si Hindi me video banaye
I have explained in Marathi language because of need of our students. Thanks for suggestion.
Sit I am from Gujarat ..i am understand only Hindi and Gujarati proper .... My English very weak ...but sir ..i have not problem for explaination Hindi .....sir creat a videos in English. I need that.
@@manjulabenmehta3833 sure. I will try. .
@@manjulabenmehta3833 Agar apko specific point ka explanation chahiye to point bhejo
Sir Please upload a video lecture on lead tetra acetate, Periodic Acid, Lithium dispropylamide,and 1,3 dithiane My exams are in 5 days please help me by uploading a video lecture it will be a great Help
Thank you so much sir 🌸😊
This video is very helpful for us 🙂
🙏
Thank u so much sir ..
Welcome
Sir in mechanism why we are adding 4 hydrogens on nickel surface randy nickel has only one hydrogen know
Metalic surface Nickel has number of Nickel atoms. Each Nickel atom forms weak bond with one Hydrogen. Therefore I have shown four hydrogen but there are number of hydrogen on Nickel surface.
Something is wrong because you told that sulphuric acid but here use hydrochloric acid...
Thanks for your comment. I have gone through the video. I have said hydrochloric acid i.e. HCl. But, if I have said sulfuric acid, then take it as hydrochloric acid.
खुप छान Excellent Teaching in simple language , concept clear ,Thank You very much sir ,it's really helpful and useful 👍
🙏
nice sir thanks
Nice sir
In 2pentanol Gemma hydrogen is that one you're doing sir
I am not getting your questions properly
@@ECHIMICA I want to say that Gemma hydrogen is not that one you're doing in case of 2 pentanol dehydration
Thanks for correcting me
I need mechanism of this reaction
Plz see video from 2.18 to 6.25 minutes... mechanism is explained
Works on which green principal??

Why electromagnetic radiation in the visible region are coloured? Why this colour is observed? Whether this observed colour is due to electric field or magnetic field?
Human eye detects the radiation in the range 400-800 nm. Colours are observed in this region is due to reflection or absorption phenomenon. When the radiation in 400-800 nm range falls on any object, then it may be completely or partially reflected or absorbed. As sun is source of light. This light is reflected by objects around us. The colour of object that we see is the colour of light reflected from that object. In this way, visible light appear coloured. It is due to reflection, absoption not due to electric or magnetic field.
Why we are taking distance between two successive crests or clepts?
We are taking distance between identical points on successive crests of clefts because this distance is nothing but complete wave. In addition, we can take distance between starting point of crest and ending point of cleft and vice versa
Very well detailed explanation with suitable examples sir. I request you to give more examples based on CSIR/NET
Thank you...i will try
Sir please provide remaining part of mass spectrometry like fragmentation pattern in sulphur , either etc
Very useful.... Thank you for your crystal clear explanation sir
Thank you
Very good lecture sir
Well explained
Very nice thank you
What I didn't understand sir, is how the (+) charge is gotten by the carbon which has a deficiency of electrons in the aromatic compound?! Please I need your answer.
When aromatic compound (say benzene) undergoes ionisation, one pi electron is lost that causes electron deficiency on carbon. Ultimately it becomes positively charged
Thank you so much ❤️
Nice explanation 👍
Thank you
Lecture 12 sir
Excellent
Thank you
Nice
Thanku you very much sir🙏 . It is very nice teaching and very helpful to me
Sir, please provide the notes and explanation fragmentation of Carboxylic acid, amide and ester like you mentioned in this group at the end
Very good content
Thanks sir
Explanation Very nice sir
Thank u
What is the driving force required for formation of free radical?
Grinding Energy and mild oxidising nature of FeCl3 is the driving force for formation of free radical.
Plz Lcms bragrand ion fragmention class.provide sir.
I am not getting what you are writing.
Please write in english if possible
Good sir
Very good,,💐💐💐
