Markovnikov’s Rule vs Anti-Markovnikov in Alkene Addition Reactions

[@michelleacquaye8771]

I laughed out loud at your answer to the question: "Leah, which one of these rules should I memorize?" Your answer "Neither"; that was great! Thank you so much for this clear video! Your pace and tone are great! Also I think your rule : "the rich get richer" can also be applied to the Nu because the C that is richer in substituents gets richer in substituents ? Again, Thank you SO much!!

0:50... instead of just saying that you are forced to name the lowest number first...and though it's correct I feel that it's easier to also add..." Everything takes the path of least resistance if no outside force is used on it"...why I think it's better is because not only are you learning a/the rule...you also learn exactly why it is the rule...understanding it instantly become extremely simple to understand and remember...the goal is to know information and remember it...not only just know it...tying multiple things together is easier to remember... even better if you have to remember lists of things is to make a short story using the first/or a few.. letters of the names of things you are trying to remember and use that in a short story /sentences... essentially it's a human zip.file and keeps more space to remember other things... people try to brute force information into their brains... guarantee that everyone struggling in school does not understand how information storage works in their brains and they try to force themselves to learn

15:26 I am so confused here - Is it correct that the product with the Bromine atom on the primary carbocation at the bottom reaction related to your alkene practice problem 1? When I clicked on the link to learn more about the material tested in that problem, the examples solely portrayed Markovnikov rule. Does this difference have something to do with the peroxide solvents? Thank you for the content!

[@Leah4sci]

Yes, the major product of this reaction will have bromine on the primary carbon. But it's important to note that there is NO carbocation intermediate in this reaction. This is a radical reaction, with a radical intermediate, that is initiated by the use of peroxides.

Leah, Just BRILLIANT! Everything is about stability yes. But you didn’t explain WHY it would be more stable adding in that position. Would adding onto the more substituted group be more stable because it can spread the extra charge load better across more carbons in the nearby vicinity? Please help.

[@utkarshbajaj8917]

Can u please tell what's the reason we use markomikoc in a reaction instead of anti markonikov

[@Leah4sci]

In organic chemistry, many reactions are regioselective, which means they follow a particular path or mechanism to produce a particular product. The product you make is heavily dependent on the reaction intermediate and its stability. In the case of alkene addition reactions, some make Markovnikov products while others are anti-Markovnikov. And this can depend on the individual mechanism of the reaction and what intermediate is formed. To learn more about the differences, make sure to read my tutorial at Leah4sci.com/Markovnikov and then print my Alkene Reactions cheat sheet where each reaction is labeled as either "Mark" or "Anti-Mark".

[@prateekshaprasad5182]

in the halo hydrin formation....why does water attack and not Cl-

[@Leah4sci]

Cl- gets completely surrounded in an aqueous solution making it feel 'trapped' and unable to reach the carbon. Since there are so many water molecules around, one of them ultimately finds the partially positive carbon and takes the opportunity to attack

[@superded6092]

How do you know when a reaction will become anti-markovnikov?

[@Leah4sci]

It really depends on the particular reaction mechanism. For instance, in radical reactions, the substituent adds to the alkene before the formation of the radical intermediate. Since we want that radical to be as stable as possible, we see the substituent adding to a less-substituted carbon to begin with. Another reason for Anti-Markovnikov products might include steric effects. To view my cheat sheet on alkene reactions, visit leah4sci.com/alkene-reactions

Leah at "9.30" (time stamp) you said the nucleophile doesn't attack the more substituted Carbon because it's greedy !! What it means !! I'm collapsed at that point. Please clear me at that point Leah. Thanks a lot for that. Looking for your answer.

[@Leah4sci]

Thanks for asking so I can clear this up for you! The nucleophile DOES attack the more substituted carbon. I think you misunderstood my statement. It’s greedy in the sense that it is negatively charged and will naturally be drawn to attack anything with a positive charge. The reason why the majority of our product is the more substituted halide is because more of the tertiary carbocation is present as an intermediate.

[@srianitha3142]

It s only hbr you can do anti markovnikove in it or al the halogene

[@Leah4sci]

The non-radical hydrohalogenation of an alkene always follows Markovnikov's rule. That would work for HCl, HBr or HI. But, the radical hydrohalogenation of an alkene with HBr would be anti-Markovnikov. Make sure to visit my tutorial and download my cheat sheet on these Alkene Reactions at Leah4sci.com/Alkene

[@rudro5784]

Thank you mam

[@Leah4sci]

Most welcome 😊

[@adiliraliyev5882]

Does Mk's rule governed by electronegativity: c-c-c (carbon between other carbons would be more positively charged, since electrons are more evenly spaced out) and h-c-h ( carbon between hydrogens would be less positively charged since it is more electronegative than hydrogen, thus pulling electrons closer), there for negative halogen would be attracted to carbon that is more positive because it is between other carbons that's share electrons more evenly making it more positive? Rule is more positive carbon would attract more negative atom.? Could this be it?

[@Leah4sci]

Yes, this is a correct observation. Markovnikov’s rule is governed by electronegativity in the sense that the more positively polarized atom will be attracted to the less substituted carbon and the more negatively polarized atom will be attracted to the more substituted carbon. As you said, a carbon between other carbons is able to share electrons more easily with neighboring atoms and, ultimately, holds a positive charge better.

The anti markonikov is really confusing passed through it a couple of times but still couldn't get it

[@Leah4sci]

Sorry you're having problems with that. Some reactions choose NOT to follow Markovnikov’s rule, and this is not because they don’t want to have stable intermediates. Actually, it’s quite the opposite. Depending on the mechanism, some reactions find that their more stable intermediate allows for addition at the less substituted carbon.
