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.

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.

@hamidmanzar2537 2 года назад

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!

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

@kingmprincea3571 4 года назад

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 4 года назад

@khamvongsa09 4 года назад

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 4 года назад

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

@torpezaincreible8692 4 года назад

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.
