Mam aap itni intilligent kaise ho Aapki hr ek video ek dam perfect hoti.. itna achha samjh me ata h ki Aapke alava koi aur teacher bhata hi nhi h...thank you so much mam 😘✌️👍👍👍
Aapke channel ke kho jane pr yuh lga jaise ab n ho payega yeh net hmse... Ye channel hmare liye.. Bahut important hai.. U know trust ka dusra naam J chemistry
Your way of explanation is tremendous but in this chapter it seems for every reaction we need a different concept. It is more memory base chapter rather than conceptual 🙄🙄
Ma'am I have confusion at 19:21 where you said that if R=R'=H then NT2 takes place. But if both the substituents are H atoms, then homolysis would produce primary radicals which will be unstable. So, I think that it should be cyclization if both the substituents are H. Please correct me if I am wrong.
Thank you mam😇 but ,We remove the hydrogen from the B-carbon where we break the A-bond, but did you remove the hydrogen from a different carbon in your first example? Why so?🤔 plz reply mi mam...❤
mam if allene is not the stable product then that four membered ring is also not stable ....that means we compare which is more stable among those two and then find the answer
Hello mam ..... Norrish type que me ...in presence of light ,photosencitizer just like acetophenone ....to product kya hoga ...n conrotatary hoga ya disrotatary ????
Mam in 5th question..gama carbon I.e 2 possibility one is right and left side. And other is upper carbon . It is possible to form cyclization with upper ring?
maam question no. 3 me CO kese release hua?? no liq. or vapour phase given and upar se jo radical form hua h wo bhi 1°radical form hua h... please explain maam
hy mam ... hope u r fine here i posted my question plxx rply ... when two alkyl groups are attached why cyclization is favoured process than norish type 2 ?why N,Type-2 is not favoured process here rply please!
In your 6th example , if you will go through Jagdamba singh's book it says it will follow Norrish type II mechanism..page no. 371...is there any reference for this mechanism that it goes via Norrish type I
In question 1 there is also bicyclic system then why not decarbonylation and if in bicyclic system vapour phase is not mentioned or other phase mentioned then what happens
But in qstn 1 there is ROH , a protic solvent, that's why. Bi cyclic system go 4 decarbonylation even in other phase. see example 3, vapour phase is not mentioned there.
Apki.jaise teacher agar main pehle pata to Shure jam clear krta......thank u mam ap aisehi video dete rahna Hum gareeb ki Ghar bas
jayegi
Mam aap itni intilligent kaise ho
Aapki hr ek video ek dam perfect hoti.. itna achha samjh me ata h ki Aapke alava koi aur teacher bhata hi nhi h...thank you so much mam 😘✌️👍👍👍
Absolutely
Coaching li hai unhone...aur jaha se li hai wha ye sab bataya jata hai...baki unki apni mehnat
Everytime at the end you say "thank you so much for watching" I repeat "thank you so much for explaining 🙏" 😊❤️
😊
@@JChemistry you replied 😃🙏❤️
Who won't reply to such a sweet comment ?
@@JChemistry ❤️🤗🤗
Axomr nki
Actually mam reality is that we should no words for ur unconditional support really. We will be very lucky to have you with us.. Thanku so much
Aapke channel ke kho jane pr yuh lga jaise ab n ho payega yeh net hmse... Ye channel hmare liye.. Bahut important hai.. U know trust ka dusra naam J chemistry
J chemistry is written on ur neck piece .....🤗🤗🤗🤗🤗.....looking 👌👌👌😍
You write very neat & clean and I really appreciate it.. thank you for everything you doing
Very helpful video. Thanks for nice upload.
Confusion door kr di apne is vdo me 1 no. Ki vdo hai apki sari...
You ve such so helping nature... Stay blessed mam...
Right♥️
Bht hi achhe se smjhaya apne thanku mam ...
Mam you are genius of organic chemistry 🔥🔥💫
Ma'am the way you explained the concept 😍.
Thank you mam for u r guidance.Explained very well .
Vry well
world was totally different that time 😢. Btw Thank you so much ma'am for explaining this wonderfully.
Outstanding explanation mam.. thank u
Ma'am, your classes are really good.
Thnkiu soooo much mam and gd mng 💐🌷🌺🌻🥀
Thanks ma'am.... You r looking gorgeous also...😊😊😊
Thank you ma'am
Very useful video. Thanks a tonne!😊
Mam u r grt 💯👍👍👍👍
Sister❤️ isolobal concept ka video karo plz...
Nice mam ...
Thank you mam
Ma'am Photochemistry ka assignment upload krdo..
thank you mam ...........................
Your way of explanation is tremendous but in this chapter it seems for every reaction we need a different concept. It is more memory base chapter rather than conceptual 🙄🙄
In first example there is also bicyclic complex system then why CO not loose from compound
First example is not bicyclic....it's tricyclic
thanks to clear my mistake
thank u for wonderful session
Ma'am I have confusion at 19:21 where you said that if R=R'=H then NT2 takes place. But if both the substituents are H atoms, then homolysis would produce primary radicals which will be unstable.

excellent
Ji thanks mam
THANKS 🙏
Thanx ma'am 🙏🙏
at 24:03 , even the cyclization of the reactant leads to a strained 4 mem ring ,then why cyclization is preferred over NOrrish type 2 rexn??
Thank you mam😇 but ,We remove the hydrogen from the B-carbon where we break the A-bond,
but did you remove the hydrogen from a different carbon in your first example? Why so?🤔 plz reply mi mam...❤
Mam tautomerism rule follow kr skte hai hmmm isme, enol se keto form ke liye, H ka migration karke, Direct bhi kr skte hai hm, exam main,
mam if allene is not the stable product then that four membered ring is also not stable ....that means we compare which is more stable among those two and then find the answer
Thank you very much mam 😊
Que no. 4)me allene unstable hai isly nahi favour nahi kara...bt cyclisation me bhi to 4 memebered ring banri jo strained hai...uska kya?
Mam cyclic me norish type 2 reaction kese hota h , bataye plzzz
Nice mam
Hello mam .....
Norrish type que me ...in presence of light ,photosencitizer just like acetophenone ....to product kya hoga ...n conrotatary hoga ya disrotatary ????
Mam in 5th question..gama carbon I.e 2 possibility one is right and left side. And other is upper carbon . It is possible to form cyclization with upper ring?
Mam ur calling elimination as NT 2. It is just the path of rxn
Mam we expect photochemistry should be upto gate level means that are mentioned in gate syllabus
Thanks mam
thanks ma'am
Mam plz explain some more examples
mam mai net ki coching ke liye delhi jana chahta hu ap bataiye ki kon se coching centre jau please mam bataiye
maam question no. 3 me CO kese release hua?? no liq. or vapour phase given and upar se jo radical form hua h wo bhi 1°radical form hua h... please explain maam
5th example me bicyclic consider krrke decarbonylation q nhi kiya h ma'am? Anyone please clear my doubt..
Same dout
Bicyclic nahi hai kyunki carbonyl bahar hai satured hai ....
hy mam ... hope u r fine
here i posted my question plxx rply ...
when two alkyl groups are attached why cyclization is favoured process than norish type 2 ?why N,Type-2 is not favoured process here
rply please!
In your 6th example , if you will go through Jagdamba singh's book it says it will follow Norrish type II mechanism..page no. 371...is there any reference for this mechanism that it goes via Norrish type I
Mam, u r writing in the black board but we have not seen clearly ur writing
Mam 1st example mai beta cleavage ho sakta hai kya kuki usme 3 membered ring hai jiski wjh se alpha beta bond weak ho jayega.
thx mam
Tysm Ma'am
Thanks
Thnku🤗
East or West, South or North.. J Chemistry is Best
In question 1 there is also bicyclic system then why not decarbonylation and if in bicyclic system vapour phase is not mentioned or other phase mentioned then what happens
Kunki decarbonylation ke liye ring se hi carbonyl gp attach hona chahiye....
But in qstn 1 there is ROH , a protic solvent, that's why.
Bi cyclic system go 4 decarbonylation even in other phase. see example 3, vapour phase is not mentioned there.
Norish type 1 = if -c=o participated in ring
Let me know if i am wrong
j smile is so 😘😘😘😘😘🤣
I have a question from norish tpye 1 can i ask???
madam bahat achha.madam apka ghar kon state me haee??
👍
Mam itne examples dekh ke complications badh jati hain
Mam 5 vi reaction ko ketone se kare to kya banega
looking so beautiful 💝💝💝💞💞
1st view
Luv u mam😘
Sound badhao
U r beautiful u r teachings very beautiful
In last..... veryyyyyyy fast.....
Mam take ur classes in english.Its sometimes difficult to follow hindi for a south indian
I want to meet you mam
Thanku so much madam
Thank you mam
Thanks mam
Thanks mam
