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

Kyonki sir aapka content bahut accha he toh usme thoda sa increment aayega toh hum acchi acchi coachings ko beat kar sakte he. Thodi si effort or lagaiye her chapter me revision vedios or banaiye. Questions community post per daliye.or bhi bahut kuchh tarike he. Sir ab voh din dur nahi jab apan History Kayam kar denge. If you agree what i m telling then please reply me. Thanks.

Hey can you please explain the first ans as my answer is 1-ethane phenyl
Sir today I have exam your class helped me a lot...... Tq🙂🙂
It's true bro

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

Answers of homework questions -
1) 1-ethenyl benzene
2) 1- methyl cyclo hex-1-ene
3) i) [ SN1 ] - butane-2-ol
ii) [ E1 ] - but-2-ene
*all are major product*
After 12th, I opted for b.pharma.
Now I am again watching this lecture after +2😎😍
Thank you so much alakh sir
Are u pcm student?
matlab pehli baar dhang se nhi dekhe the lectures ;-;
Yes u r right, me too watching for Gpat...

19:30 Sir singing "Candy po po" 🤣
23:44 SN1 & E1 goes together.
1) temp is high, E1- major product,
2) temp is low, SN - major product.
HW:
(i): 1-phenyl eth-1-ene
(ii): (major) -> 1-methyl cyclohexene, (minor) -> 1-cyclohexyl ethene
(iii)(i): butan-2-ol
(iii)(ii): (major) -> but-2-ene, (minor) -> butene.
(ii) minor---> 1-methylidene cyclohexane
Methylene cyclohexane is minor
And in 3rd trans bute 2 ene

Alakh sir, I have a suggestion for you. Aap sabhi lectures bahut hi acche tarike se complete kar rahe ho. Agar aap apna content thoda sa badha doge or her chapter me 2-3 vedios bada doge jisme Advance level tak ke conceptual questions ho. Kyonki sir aapka content bahut accha he toh usme thoda sa increment aayega toh hum acchi acchi coachings ko beat kar sakte he. Thodi si effort or lagaiye her chapter me revision vedios or banaiye. Questions community post per daliye.or bhi bahut kuchh tarike he. Sir ab voh din dur nahi jab apan History Kayam kar denge. If you agree what i m telling then please reply me. Thanks.
look you told absolutely correct. just to remind you of your comment u did 3 yrs ago , nice bro

Understood the concepts well. Thanks, Sir ❤️

Wow Awesome voice start at 19:22
19:10-9:52 Tony kakkar ki aatma aa gyi thi sir me, ek hi lyrics repeat kiye ja rhe the😂
Wow sir u are the best.......Best Lecture on elimination in whole RUclips.....
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😊
Sir love you from bottom of my heart ❤😊. Sir ye reaction mujhe kab samjah me nahi aarahi thi abhi sab clear hogaya thanks a lot sir 🙏. Love u sir ❤
Always ethentic ideas clear concept topic completion only physics wala thank uh sir 😍 u r doing great job sir ☺️
43:23 Major product - Saytzeff product &
minor product - Hoffmann product.
@19:36 you write R-CH(OCH3)-CH2 in which Carbon valency is not full filled in CH2 please correct it
Bhai itne samajhdar ho ki tum khud bhi thick kar sakte ho
You take fix 1hr in E1 reaction , that's the property of intelligent teacher, ''JUG JUG JIO''
Sir i have no words for appreciating you
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
Very well explained.. Thankyou for ur efforts.
