God bless you.
I think at 9:52, we have a primary carbon and a tertiary carbon. Thank you so much for making these videos. They have been saving me.
yeah you're right
totally agree, but its ok, he is legend
I credit my Ochem success this semester to your videos. THANK YOU!
My professor had to go through multiple examples and I was still confused at the end. I watch your 12 minute videos and understand everything I should know by now. Thanks 🙏🏼
Do I understand this video? Hell yeah
Does my teacher teach to make me understand? NaBro
XD
him not explaning it properly dosen't mean he dont want you to understand, that's kinda mean.
@@SIZLIANO a😂ap😂😂
I like the explanations. My teacher just explains this as ‘ok so simply, hydrogen attaches to end breaking the double bond, carbocation in middle, that bonds with negative bromine. Done , easy see...’ and that’s her done...
At 9:50 you label a carbon that's connected to three other carbons as secondary carbon. Shouldn't it be a tertiary carbon?
yes
@@ethanlittlestone1122 No, double bonds cannot be classified.
@shyl venk he did in the example prior..if you "cant consider the carbon attached to double bond", then the last example would only have primary carbocations sooo
@@raeanne5793 So is it actually tertiary carbon or second?? Can you explain?
@@someone-yj2im it would be a tertiary carbon, I believe he just made a mistake in the video. It is a tertiary carbon because when the electrons from the double bond attacks the H-Br, that double bond goes away and you are left with two possible carbocations. I think viewing the skeletal structure makes it easier to see this so I linked the google doc I created that shows you. here is the link: docs.google.com/document/d/1QXvka44V0s5bEpC-orfS9ECNug5IbPx2CXonhBiCBzE/edit?usp=sharing
Carbocation #1 in the google doc shows that it is a tertiary carbon, and Carbocation #2 is a primary carbon. Let me know if this helped, or if you need it explained differently! (:
Shouldn't that be a tertiary carbon instead of a secondary carbon in the last example?
How do you determine the major product for the Alkene where the both carbons in the double bond are secondary carbons.
ahh yes, here I am again, after attending lecture and reading my book and still not understanding :)
you are my saviour
Ahhh, ok....I still don't get it
What's an MTP orbital?
Jaqueline Rios you heard a little wrong;
it’s an empty ‘p’ orbital
8:12 its actually 2-bromoPENtane
In the second reaction, correct me if I’m wrong but it isn’t you major product because u had to do a hydride shift
thank you very much ✌
When do we perform hydrogen shift and when do we do methyl shift?
How do i identify the secondary carbon and the primary carbon?
In last example for HBr, there is 3rd carbonation, and a primary one, there is no 2ndery carbonation in the question, while you keep say 2nd ....
Anyone know what application he uses to draw?
Dwell much on explaining how oxygen stabilizes the primary carbocation
Is there a chiral center on the last example, resulting in racemic enantiomers?
Gannaa key rus ko khumbhi sey sadao to kya methane nahin ban jayegi??? Hydrogen mix karo kuch ghee jaise ban jayegi😇😇😇😇
Thank you for being helpful but do you have any videos on general organic chemistry reactions? I'm in first year Chemistry.
What are the products formed when Bromine Water reacts with 2-methylpropene ?
I think besides the hydrobromination,the alkene also undergo a reaction with the hydroxyl group,forming pentanol as well.
When alkene react with bromine water anti addition takes place and it proceeds though cyclic transition state
You helped me through out hard times please don’t ignore me and respond it I’ll mean much more than a reply to me.
11:53 isn't that tertiary?
Yes, I think he made a mistake there
6:22 how did you know the structure switched like that
👏👏👏👏am crazy about you!!
why is the major structure more stable?
Why doesn't Br ever make a bond that's in the plane of the page: why is it always either dashed or wedged?
Csp3 is planar, the P orbitals are the only ones which can react, so it goes either up or down
Is that Br going to have and enantiomer since theres a chiral center
Why are you ignoring hyperconjugation effect
wbat if HBR is in excess
a what kind of mixture? receding????
Racemic
I LOVE YOU
Going to National sains competition
this nothing but carbocatiom rearangement mechanism
I’m cooked bro
We're all Cooked
