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.

[@Bofadeez467]

yeah you're right

[@兔子和花椰菜]

totally agree, but its ok, he is legend

[@maiwanmussa1238]

I credit my Ochem success this semester to your videos. THANK YOU!

[@tomatrix7525]

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...

[@lebronjames5176]

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 🙏🏼

[@saliksyd4714]

God bless you.

[@Ralovelyb]

Do I understand this video? Hell yeah Does my teacher teach to make me understand? NaBro

[@Dr.ben.nutrition]

him not explaning it properly dosen't mean he dont want you to understand, that's kinda mean.

[@frukten7020]

For the last question wouldn't we have a racemic mixture because the carbon is Sp3 hybridized and connected to 4 different things

[@sambrailsford3800]

At 9:50 you label a carbon that's connected to three other carbons as secondary carbon. Shouldn't it be a tertiary carbon?

[@ethanlittlestone1122]

yes

[@janichka95]

@@ethanlittlestone1122 No, double bonds cannot be classified.

[@raeanne5793]

@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

[@someone-yj2im]

@@raeanne5793 So is it actually tertiary carbon or second?? Can you explain?

[@raeanne5793]

@@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! (:

[@prestonemulala7645]

How do you determine the major product for the Alkene where the both carbons in the double bond are secondary carbons.

[@RawDoggin_78]

you are my saviour

[@britneymack8664]

Shouldn't that be a tertiary carbon instead of a secondary carbon in the last example?

[@Shahboyy]

8:12 its actually 2-bromoPENtane

[@alvarez321]

Ahhh, ok....I still don't get it

[@sofzhuk1188]

ahh yes, here I am again, after attending lecture and reading my book and still not understanding :)

[@JayPatel-ql1pj]

Is there a chiral center on the last example, resulting in racemic enantiomers?

[@eliyahbohadana3172]

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

[@prestonemulala7645]

Dwell much on explaining how oxygen stabilizes the primary carbocation

[@amacgregor92]

Anyone know what application he uses to draw?

[@jaquelinerios2740]

What's an MTP orbital?

[@nourelshabassy8158]

Jaqueline Rios you heard a little wrong; it’s an empty ‘p’ orbital

[@amnalayth1841]

thank you very much ✌

[@olamideajayi247]

How do i identify the secondary carbon and the primary carbon?

[@janeb9986]

What are the products formed when Bromine Water reacts with 2-methylpropene ?

[@NguyenNhan-yk3sr]

I think besides the hydrobromination,the alkene also undergo a reaction with the hydroxyl group,forming pentanol as well.

[@ArshSahu]

When alkene react with bromine water anti addition takes place and it proceeds though cyclic transition state

Gannaa key rus ko khumbhi sey sadao to kya methane nahin ban jayegi??? Hydrogen mix karo kuch ghee jaise ban jayegi😇😇😇😇

[@夸父逐日-i2p]

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 ....

[@talyaxagh5291]

When do we perform hydrogen shift and when do we do methyl shift?

[@karanghuman3336]

Thank you for being helpful but do you have any videos on general organic chemistry reactions? I'm in first year Chemistry.

[@strugglingcollegestudent]

6:22 how did you know the structure switched like that

[@Andrew-kh7rz]

11:53 isn't that tertiary?

[@adityaanand2621]

Yes, I think he made a mistake there

[@sanchez5963]

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.

[@alhassanmichael306]

👏👏👏👏am crazy about you!!

[@sphanie]

why is the major structure more stable?

[@cilened.s1788]

Is that Br going to have and enantiomer since theres a chiral center

[@EllieStanek]

that was also my question

[@jessiez2807]

Why doesn't Br ever make a bond that's in the plane of the page: why is it always either dashed or wedged?

[@werewolwolf]

Csp3 is planar, the P orbitals are the only ones which can react, so it goes either up or down

[@siobhanquinn4635]

a what kind of mixture? receding????

[@TungstenWu]

Racemic

[@adhitya3573]

wbat if HBR is in excess
