Question 1 - 1-phenyl ethene Question 2 - 2 products will be there but major one is 1- methyl cyclo hex-1- Ene Question 3 - SN1( low temperature product) Butan-2-ol E1 product ( But-2-ene) major + (But-1-ene) minor.
@john nelson In question 1 it is not the major product ,it is the only product. Here rearrangement is not allowed bcz it will break the aromaticity of benzene. Hope it will help.
1: 1-phenyl-ethene 2: 1-methyl cyclohexene (Satzeff product) and 2-cyclohexyl ethene (Hoffman product) 3: butan-2-ol (SN1) at low temperature and but-2-ene (Major) , butene (Minor) -----> for elimination rxn at high temperature

In SN1 lecture, sir ne 1 point likhaya tha, "Rearrangement of carbocation takes place. This will not effect the rate". Arrangement sirf carbocation mai hota hai.. free radical and carboanion mai nhi hota hai.

I LOVE ORGANIC CHEMISTRY LEARN AT MIGHT
RIP english
What the heck do you mean lmao. "learn at might"
Refractive index = velocity(+)/velocity(+) so + extensive
As density = mass(-) / volume (-) so density + so extensive

Answer 1). 1-ethenylbenzene
Answer2). 1-methyl cyclohex-1-ene. {Major product }
1-methylene cyclohexane {minor product}
Answer3 ). EN1. But-2-ene. {major product}
But-1-ene
SN1. But-2-ol
19:30 Sir singing "Candy po po" 🤣
#Homework
1)ethenyl benzene
2)1 methyl cyclo hex-1-ene (major)
Methyledene cyclo hexane (minor)
3)at 10°C-SN1 : butan-2-ol
at 60°C-EN1: Trans but-2-ene(major)
Cis but-2-ene(minor)
but-1-ene(minor-hoffman)

Concept crystal clear sir ✨✨📙📒
39:09 Zaitsev Rule ( Beta - elimination reaction dehydrohalogenation )
Sir today I have exam your class helped me a lot...... Tq🙂🙂
It's true bro
I think Sir apka channel esa Pehela study channel hoga jiske 1 million subs hone vale he🎉🎉🎉🎉
Understood the concepts well. Thanks, Sir ❤️
Answers:-
1. 1 phenyl ethene
2. Major-> 1 methyl cyclohexene and Minor-> 1 methylene cyclohexane
3. SN1-> butan 2 ol
E1:- major-> but 2 ene minor -> but 1 ene
Last one elimination reaction would have structural isomers so
{Trans-But-2-ene} is more correct😊
23:44 SN1 & E1 goes together.
1) temp is high, E1- major product,
2) temp is low, SN - major product.
In 49:54 why aren't we taking ring expansion??????????
0 disliked one and only one teacher that is alakh sir🥰🥰🥰🥰🔥🔥🔥🔥
To all the people out here, It's OK that you are requesting for a particular chapter but at least appreciate the efforts of the teacher before requesting
As electric flux= electric feild(-)×area (-)=+ so flux scalar
As p.d (potential diff)= work (+)/ q(+) so p.d (+) scalar
Force = mass(+)× displacement(-)
So force vector
SCALAR

My name is "physics wallah "and this is your beautiful sa channel "Alakh Pandey " Sir this is so funny 😜 aap hmlog ko padhate padhate bhul gaye ki your name is Alakh" pandey" And this is your beautiful sa channel "Physics wallah" This also happens in our school sometimes teacher forgets what to teach and they used to say aap jaise bacchon ko padhate padhate bhul gaye ki padhana kya h 🤣🤣🤣🤣
Wow Awesome voice start at 19:22

@47:28 sir Sn1 me toh rearrangement nhi krte hai na.....apne Sn1 me ekk example ke through btya tha....
In SN1 lecture, sir ne 1 point likhaya tha, "Rearrangement of carbocation takes place. This will not effect the rate". Arrangement sirf carbocation mai hota hai.. free radical and carboanion mai nhi hota hai.
