Circled ones doubt unless question number is mentioned.
4)-C? Carbocation rearrangement
4 C 5 A? @seshu_ram
3 pic Q-5 this is a case of ring expansion
4 B 5 A.
Guys one doubt..
Please watch this
At 7:00 - 7:40 hasn't sir made a mistake by calling the products cis trans? I think you should use EZ nomenclature.
He continues saying cis trans through the rest of the video in some places. But for cis trans isn't it necessary to have 2 same groups?
For the last doubt,
Use 1 eqv HBr at 40° C or at a higher temperature to form the TCP.
Guys I got these questions. Sorry I forgot to mention and really sorry for wasting your precious time. Now I just need to know the doubt in the video(ATP waala).. Anyways, thanks for taking time off your tight schedule!
@seshu_ram E, Z would have been neat but it isnt mandatory.
Here you may use E,Z nomenclature without giving it a second thought
and vice versa
The most prior groups needs to be on the same side to qualify for being cis. End of story.
Yes bro but in the case which sir has shown, in one part bromine is attached to alkyl part and the other is a simple alkyl chain. This cannot be cis trans.
This is what I got from IUPACs' website
Then going by your logic.. Lets say we have 4 halo groups attached in 2 butene.. cis trans? Naming?
Gotcha. Silly me😂
imo There's nothing wrong with cis trans bro.
Watch this from 15:00 @seshu_ram
I forgot the question bro. Let me revisit and come back.
What I meant was for something like this.
That's what I was saying (refer the video above)
That if there are exactly two hydrogen attached to alkene we can use cis -trans
cis when the two other groups are on the same side of the double bond
Yes bhaiya but Sir has attached alkyl groups there in the example but here I’m attaching bromine and alkyl. Will it be applicable in both cases? See reason I’m asking so much is because I’ve never come across this in any good book.
