I'm usually not one to leave comments on youtube videos but man have you saved my life in orgo! I'm personally thanking you for me being successful in this course. Seriously every topic I've struggled on this guy has a video on and explains it perfectly! get this guy a nobel peace prize. give him a million dollars. You are a service to humanity!! Thank you for these awesome videos and have the happiest of holidays. YOU ROCK!

Great video, but the reason the pi bond attacks the boron in the borane molecule is because the boron has an empty p-orbital, not because of the inductive effects or partial charges.

I think there was a mistake I thought anti-Markovknicov added the H group to the less substituted group, the video shows that it's added the more at 11:22 that would be just the normal rule wouldn't it?

[@KingSpriteOSRS]

king m prince a marks tool

[@khamvongsa09]

Markovnikovs rule is when the H atom is bounded to the less substituted carbon atom as in hydrohalogenation so when it’s anti markovnikovs rule H is bonded to the more substituted carbon. There is not a mistake what he did is correct. Since the OH for hydroboration and oxidation is on the less substituted carbon atom.

[@LianaFadliyeva]

anti-Markovnikov - adds to the most substituted side of the double bond. Markovnikov - adds to the least substituted side of the double bond.

[@hamidmanzar2537]

One thing I'm still confused about is how to decide if BH3 or OH will react with our given hydrocarbon. For the first reaction, I thought it was going to be the BH3 that would react with the alkene carbon chain and was surprised that you reacted with OH instead, and this was also the case with me with the reaction at 10:57. Could you make a video on how to determine which reactant is going to react with our given hydrocarbon? If you already have such a video then could you direct me to it? Thanks!

[@josgamingarena2465]

the alchohol will go to the less substituted carbon according to anti markovnikovs rule

[@arias8ale]

I guess it’s just deciding and knowing when to use anti markovovnikov

Please clarify the 2:54. Which one is partially positive? Negative?

I just don't understand how Boron has these R groups at 3:43. Where did they come from?

[@manikantan4809]

see the reactant side it has butene that is the R group. don't confuse or assume to yourself that we can only use one mole of the given reactant.

Why syn addition at 12:20 ?

[@AbdullahAlyasiri]

because they are added on the same side, both of them are wedges.

[@chacha9674]

@@AbdullahAlyasiri so why are they added on the same side? What if I draw them not wedges? Does it matter?

[@qarif9380]

@@chacha9674 No it doesn't matter. Both wedges or both dashes. They just have to have the same stereochemistry.

Yes :)

[@lavdeepsandhu2731]

No it means it’s added to the least substituted side

[@torpezaincreible8692]

It depends on whether you're talking about -ve or +ve substrate. If it's -ve it will go on more substituted carbon and if it's +ve substrate then it will be added to least substituted one.

I think this mechanism is incorrect. Up until the addition of -OOH is good. But -OOH should be added 3 times to make BO3R3 according to both my textbook and professor's slides before any leaving of -OR

Boron chemistry is so weird, like its similar to carbon in properties but it acts almost like a proton most of the time- since it can actually make lots of bonds as well, it also can do so much complex catalysis. Wack.

What if both are same degree Carbon?

then it would be symmetric and it would be the same deal if you do with any one of the carbon so no worries
