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!

[@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 🙏🏼

[@Ralovelyb]

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

[@jcmick8430]

XD

[@Dr.ben.nutrition]

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

[@saliksyd4714]

God bless 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...

[@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! (:

[@frukten7020]

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

[@britneymack8664]

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

[@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

[@Shahboyy]

8:12 its actually 2-bromoPENtane

[@strugglingcollegestudent]

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

[@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

[@JayPatel-ql1pj]

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

[@sofzhuk1188]

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

[@talyaagha]

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

[@Andrew-kh7rz]

11:53 isn't that tertiary?

[@adityaanand2621]

Yes, I think he made a mistake there

[@karanghuman3336]

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

[@jaquelinerios2740]

What's an MTP orbital?

[@nourelshabassy8158]

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

[@olamideajayi247]

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

[@amacgregor92]

Anyone know what application he uses to draw?

[@alvarez321]

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

[@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

[@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 ....

[@alhassanmichael306]

👏👏👏👏am crazy about you!!

[@prestonemulala7645]

Dwell much on explaining how oxygen stabilizes the primary carbocation

[@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

[@cilened.s1788]

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

[@EllieStanek]

that was also my question

[@sphanie]

why is the major structure more stable?

[@adhitya3573]

wbat if HBR is in excess

[@ArshSahu]

Why are you ignoring hyperconjugation effect

[@siobhanquinn4635]

a what kind of mixture? receding????

[@TungstenWu]

Racemic
