sir there is no alpha hydrogen present when the carbon is attached to the benzene ring as carbon only has four bonds but there youve showed it to be 5 but the overall lecture was very helpful
8:08 metamer kese honge jbki 2 nd 3 m same c atom nh ke dono side position isomer toh tbhi honge jb diff posiotion hogi grp ki bo bi same solve this doubt if anyone
The alpha carbon (Cα) in organic molecules refers to the first carbon atom that attaches to a functional group, such as a carbonyl. An alpha (symbol: α) hydrogen is a hydrogen atom on an alpha carbon in an organic molecule; a hydrogen atom on a beta carbon is a beta hydrogen, and so on (α, ß, γ, δ…).
Hlo sir,,,,, tautomerism ke lia at least 1alpha hydrogen chahie, but example me ap bata rahe ha benzene me -cho group aya to alpha hydrogen ha,, but alpha position me carbon ka valency pahele se 4 ha,,, to fir -cho ki pas ka alpha carbon me to hydrogen nhi ayega,, to fir tautomerism nhi dikh ayega,,, 👍

They are metamers dear & in 2nd and 3rd the parent chain is of same number of c-atoms & functional group is at different positions because if we observe carefully the position of NH is at 1st position in 2nd and at 2nd position in 3rd example
At 6: 46 question is not clear. 1 and 3 rd should be correct answer. No. Of carbon chain same in 1 and 2 so they can be postional isomers and not same in 3rd . Also you explained in last vedio example. Check it.

At 17 : 21 and 18 : 42 there is on alpha hydrogen , sorry for the mistake
Nice proffersor of chemistry. The word dear generates a feeling of attachment to the teacher.
18:03 alpha hydrogen h hi nhi konsa sp2 carbon
Thankyou so much sir ......for your this great work.....☺️☺️☺️😊😊😊😊🙏🙏🙏🙏🙏 you are brilliant explainer 🙏🙏🌍🌍🌍🌍🌍
Awesome👍👍👍 Lecture & Your teching style is wonderful.
To good sir ji and very helpful this viedo .... Please keep it up sir ..... Thank you so much sir 🙏🙏🙏🙏🙏
Thank you sir....pls complete all.
At 19:43 you mentioned 5 bond of Carbon (there is no alpha hydrogen)
Yeah dude I think the ring is cyclic but not the benzene ring 😊👍👍
Yes....there is no alpha hydrogen.

Thanks for the video sir plz make video on inorganic chemistry plz🙏🙏🙏🙏
Thnkiiwwweeee sooo much sir 🤗🤗🤗🤗aapne bhot ache explain kiya h sb kuch 🤗🤗🤗
Excellent 👍💯 work
Awesome lecture sir
bhiaya..you should teach on front of camera ..best teacher of chemistry
Appp bhooooooot hi zyada acha samjhaty han thank youu🌼
Sir 17:27 pr dono carbons ki valency 4 complete ho chuki h, isliye un dono carbon atoms pr H atom nhi aayega i think
Yesss
Ha galti ho gyi sir se
So there will be ultimately no alpha hydrogen making it impossible for it to have tautomerism?
Thank you so much sir❤🎉😊
Questions are very good
Very helpful video dear sir😊
Sir sp2 carbon does not carry any alpha hydrogen atoms in benzene ring with the functional groups CHO think the ring is cyclic
Please explain your doubt more clearly dear .
@@Chemboost Sir there is no hydrogen at 17:00
18:59 first question mein aap ne benzene me 1 alpha hydrogen dikhaya hai but there is no alpha hydrogen.
Please explain
Carbon is tetravalent ( having a valency of four ) dear .
@@Chemboost but sir the valancy of c is full so there is no alpha h
very well explained .👍👍👍👍

Sir ur teaching style is fam☺️
I have a doubt in calculating D.B.E of C5H8 .. According toh BODMAS it's ans should be 0 not 2...
Please clear my doubt
Can you please mention the exact duration of your doubt dear ?

I am having same doubt
well explained sir
Nice 👍
Nice sir♥️
17:30 sir you are making 5 bonds on the carbon atom. There will be no hydrogen atom on the carbon atom.
Nice video Sir. 😀🙏
Sir can you upload minimum data size video.
Sirrr plzzzz ionic equilibrium krva dijiye,😢😢

Sir, try to use white board instead of black board😀
Lakin mast Inka explanation
Wese green board hai na ki black 🤣😂
@@tannugupta7225right 👍
18:02 par alpha hydrogen hai hi nahi sir
Sir please upload more videos for bsc 1st year new sullybus
In tautomerism benzophenoe does not have any alpha hydrogen because it is sp2 hybridized and full fill all valency and it's a quaternary carbon.
Can you please mention the exact duration of your doubt dear ?
Use white board and marker .. Please 🙏
Thanks you sir❤️❤️❤️
sir tautomerism mai sp2 carbon hai vo kaise pata chalega
If >c=c< is present dear then hybridisation of c is sp2
Sir what is alpha carbon and alpha hydrogen
The alpha carbon (Cα) in organic molecules refers to the first carbon atom that attaches to a functional group, such as a carbonyl.
An alpha (symbol: α) hydrogen is a hydrogen atom on an alpha carbon in an organic molecule; a hydrogen atom on a beta carbon is a beta hydrogen, and so on (α, ß, γ, δ…).

Sir C6H5-CO-C6H5 or C6H5-CHO me alpha Hydrogen h hi nhi😢
Bcz Ring wala jo C h uski to valency puri ho jaa rhi na
1 Double bond + 2 single bond🙃
Sir in the first question of this lecture answer may be option ( a) and (c) is correct
Yes...I also think...that
