Great video explaining these reactions! My professor tends to lose me by going into too much detail and forgetting that we are not all professionals in OCHEM. This video gives me exactly what I need to know about each reaction in a simplified manner! Thank you!

[@Leah4sci]

So many professors forget that the reason they have students is that it is their job to teach chemistry to those who don't yet know it! I'm glad my videos are able to fill in where your professor is unable to

[@mickikeiser2028]

This was so great! It eliminated the need to review all the videos (that I have already watched several times while learning the concepts), in a compact, "remember these" concepts way. Perfect for day before finals review!

[@Leah4sci]

that was exactly the point! so glad to help Make sure you try the practice quiz once you feel confident with all the reactions

at 4:43 shouldn't the oh group attach to the tertiary carbon because of the stability of the 3° cabocation?

[@DJoeLawless]

I was thinking the same thing. I expected a hydride shift

[@OPT15]

In this case there is no carbocation intermediate. The nucleophile (H2O) attacks the delta positive carbon on the bromonium. Because there's no true carbocation, no rearrangement

[@Leah4sci]

There's no 'free' carbocation in this reaction. Instead it's a partially positive carbon held in place by the bromonium. OH is attracted to the partially positive carbon and IN attacking, breaks the carbon-bromine bond. Without a free carbocation there is no shift

How do I know if a reaction will do an anti markovnikov addition or a markovinkov addition? Is it just purely memorizing which reaction does what or is there some trick

[@Leah4sci]

To understand why any given reaction produces a Markovnikov or anti-Markovnikov product, you must understand something about the reaction mechanism itself. Determining the favored product of the reaction is really all about identifying the reaction intermediate. In short, Markovnikov reactions usually have highly stable carbocation intermediates, while anti-Markovnikov reactions do not show a carbocation intermediate.

how can we apply the reaction on the alkene working backwards

[@Leah4sci]

Look at the clues you see in the products and ask 'what reaction do I know that will give me this product?' this is how I start

[@dejurejones2783]

Im not sure if you realized but you contradicted yourself for the halohydrin. you mentioned that the halogen goes to the less substituted (markovnikov because more H bonds) but then you said that this is a markovnikov reaction because the solvent without the H adds to the more substituted carbon which is the opposite of markovnikov.

[@Llamitadelosandes]

Dejure Jones omg I’m so glad you saw that too!

[@Leah4sci]

Thanks for watching and for your comment! I do not believe I contradicted myself. Halohydrin formation is a Markovnikov reaction because the nucleophile (in this case, the polar protic solvent) adds to the more substituted carbon. It is the solvent, not the halogen, that adds last in the reaction mechanism. For the complete breakdown of the reaction mechanism, visit leah4sci.com/halohydrin-formation/

[@RichBest8910]

[@Leah4sci]

Hi! I was wondering why there is a hydride shift in the hydrohalogenation, but not any of the others shown given that true same alkene is being used in each mechanism. Doesn’t each alkene reaction exhibit a carbocation intermediate, and if so, why do the other examples not go through a hydride shift?

[@joeburreaux7953]

My textbook (Wade) says that Oxymercuration-Demurcation/Alko... has no stereochemistry, so there's no Anti/Syn

[@Leah4sci]

From a stereochemical perspective, oxymercuration is an anti addition. This has to do with the formation of the mercurinium ion as an intermediate. The nucleophile cannot attack from the same side as the mercury because of steric hindrance.

[@Leah4sci]

Listen to my explanation in the video one more time. For this example, there is a hydride shift that allows the carbocation to be formed on the more substituted, tertiary carbon.

for the last reaction, cyclopropanation an alkene can be reacted with CH2N2/UV light for the same product?

[@Leah4sci]

Yes, those are also acceptable reagents for the cyclopropanation of an alkene.

[@pmat2757]

In the halohydrogenation 4:32 would there be a carbocation shift towards the tertiary carbon so that OH would be on the more carbon

[@Leah4sci]

Actually, no. The formation of the halonium ion intermediate prevents the possibility of a carbocation rearrangement. For more on this reaction, watch my video at kzbin.info/www/bejne/iV6VdJR-ec2AnKs

[@deepanarayanan9119]

can u xplain markovnikov and anti markovnikov effect?

[@lilmissexotic]

It depends on the reaction/reagent you're using. For example, in an HBr reaction, the Br gets added on to the side of the pi-bond that is MORE substituted and the H gets added to the less sub carbon (this is Markovnikov addition). In contrast, an HBr reaction using ROOR (peroxide) as a reagent would follow Anti-Markovnikov addition ----> where the H would be placed on the more sub carbon and the Br would go on the LESS sub carbon.

[@Leah4sci]

Yes, I have an entire video on it (new) see it on this page: leah4sci.com/alkene-reactions

As such, I would watch this video either first (as a preview of what’s to come) or watch it last (as a quick review of everything). For the entire series, in correct order, visit my website at leah4sci.com/alkene-reactions

[@Amy-se5ld]

How do you know when a carbocation will form?

[@Leah4sci]

If the pi bond reaches out to attack another atom, it only attaches to ONE of the 2 sp2 carbon atoms. The other will be a carbocation as a result of being abandoned by the bond

[@haanhnguyen8776]

hii, thanks for the video, it was really helpful. but im still a bit confused at the Halohydrin process, according to what u said it should be following mark's rules, but if thats the case, why does the H-shift from tert-C to sec-C doesnt happen to form tert-Carbionium ion, since it would be more stable, and the end product would then be 4bromo 2methyl 2ol butan ?

[@haanhnguyen8776]

i am having my finals next week and now im going through all of your videos, they are really helpful, thank you so much

[@haanhnguyen8776]

im currently thinking its because of the intermediate, where both C of the double form form a bond with Br, which gives them the positive partial charge, and the H-shift doesnt like the positive charge so much, but the OH- ion does, thats why the OH-Ion jump right into the sec-C, but wouldnt that make it an anti marks product?

[@Leah4sci]

The intermediate is the key here! Rather than having any sort of hydride shift, what we see in this mechanism is the formation of a halonium intermediate where the halogen (in this case, bromine) forms a bridged intermediate across the former pi bond. But even in this bridged intermediate, we see a preference for the partial positive charge to fall on the more substituted position. Therefore, the alcohol comes in and attaches to that more substituted carbocation (the Markovnikov position) in the second step. For more on the mechanism of the halohydrin formation, make sure to see my video at Leah4sci.com/halohydrin

[@haanhnguyen8776]

@@Leah4sci Thanks for the explaination x) I had my orgo 1 final today and your videos really helped me a lot !

[@chander.261]

4:46 ma'am could you kindly explain why the hydroxyl group didn't go to the more substituted tert carbon next door ?

[@Leah4sci]

To understand, we need to look more closely at the mechanism of the halohydrin formation. There is no carbocation intermediate formed, but rather a halonium ion which stabilizes the positive charge and prevents rearrangement. Check out more on this mechanism by visiting leah4sci.com/halohydrin-formation-alkene-reaction-mechanism/

[@SpeakOutShyness]

at 4:07 why does it look like both bromines are added to the same side? If the reaction is supposed to proceed with anti stereochemistry doesn't that mean both Br atoms come from opposite faces of the double bond? You only form the trans isomer right?

[@Leah4sci]

while you are absolutely correct this version of the product does not show stereochemistry as denoted by the lines rather than dashes and wedges. It does however state 'anti' to remind you that this is an anti addition

everything was purely explained and thnc for clarifying some tricky things. But mem i only have ONE PROBLEM "HOW DO YOU SEE IF YOU AN HYDRIDE SHIFT"??????

[@Leah4sci]

Glad I helped clear things up for you. Regarding your questions, a hydride shift can occur in organic chemistry reactions that involve a carbocation intermediate. If such a rearrangement will place the carbocation on a more substituted carbon, then the hydride shift is highly favorable because of its ability to stabilize the intermediate.

Hello leah can you check back the oxidative cleavage with hot KMnO4 in your cheat sheet..? the 2nd products in the cheat sheet gives formic acid (HCOOH) but in your video 11:57 it gives CO2

[@affin1176]

I'm guessing the CO2 as the 2nd product is correct. After cleavage the unsubstituted carbon should become CO2, monosubstituted become COOH and disubstituted become ketone

[@Leah4sci]

Yes, you are absolutely right! Thank you for pointing this out. The correct second product of the oxidative cleavage reaction with KMnO4 would be CO2. A terminal carbon on an alkene will be fully oxidized. Again, thank you! We will correct the alkenes cheat sheet on our site.
