Id just like to thank you for all the videos you put out. It has helped me get a 95/100 on my Ochem Exam and I am so beyond greatful that you are here to teach. Keep doing what you are doing because you're making positive changes in students lives. I was in a negative mindset due to my first exam score being soso low. But these videos gave me hope and it really did change my thoughts and how I felt. I no longer feel like a failure and these videos are the reason for that. Keep fighting through everyone!! I am taking my final exam today :)

Honestly I wasn’t doing great in organic until I started skipping class. I’m great at pattern recognition (need a ton more data than is provided in class) and learning but horrible in the class setting teachers always talk to slow and don’t challenge me enough to be interested. Here I can just play everything 1.5- 2x speed pause and solve the problem and easily and quickly figure out where I messed up. Normal pace in class kills me and I can not help but zone out. But i can easily absorb everything discussed in class in 20 min by myself. Which is probably the amount of time I actually pay attention in normal class. I can’t remember anything but if I just throw myself into the information and expose myself to as many situations and problems as possible it clicks and all of a sudden and I see everything as images and videos in my head. It makes learning feel like a drug and you get high on the excitement of everything magically fitting together. Learning in class feels like hell the education system has a way of sucking the excitement of even the most interesting of things.

@49:40min the protected -NH2 forming amide group, is it still possible to be protonated under acid conditions (HNO3/H2SO4) to deactivate the reactivity of the benzene ring?
@felipe-n9t
@felipe-n9t 9 месяцев назад
56:23 would it even be possible to add a terbutyl group to this ring? Considering that the Friedel Craft's reaction can't occur because the ring is being deactivated by two EWGs, and the other reaction that leads to an alkylation of the benzene ring shown in the video is the one where you add a bromide and then you react this product with (R)2CuLi, but here you already have a bromide on the ring, so you would have many possible side products here(although the product where the Terbutyl group is in the Para position with respect to the nitro group would be the major product of this hypothetical bromation+alkylation reaction route if it is even possible). So i don't think this synthetic route shown in the video is even possible, and if it is, then it's not entirely accurate. But given that this clearly was not the best synthetic route to get to the intended product anyways, it doesn't really matter if it's not 100% correct.

At 22:55 why is the benzene with the more substituted carbon the major product? Does benzene prefer more more substituted rearrangements in general?

7:39: 🔬 The video explains the reaction of benzene with concentrated sulfuric acid and heat. 14:18: 🧪 The video discusses the reaction between br2 and febr3 with isopropyl and methyl groups, and predicts the major product based on steric effects. 21:34: 💡 The major product in the Friedel-Crafts alkylation reaction is determined by the accessibility of the para position and the bulkiness of the substituent group. 27:59: 🔬 The Friedel-Crafts alkylation reaction has limitations and does not work with strongly deactivating groups like NO2. 34:18: 🔬 The video explains the Gatamine Koch reaction as a method to convert benzene into benzaldehyde. 41:05: 🔬 The video discusses the synthesis of benzoic acid through the addition of an alkyl group and subsequent oxidation. 48:03: 🧪 The video discusses the conversion of an amine to an amide and the subsequent nitration reaction. 55:12: 🔬 The video discusses the use of blocking groups in organic synthesis to control the placement of substituents on aromatic rings.

two questions, 1. at 43:26 I realized that he's using potassium permanganate in heat and basic conditions to oxidize to a carboxylic acid, but shouldn't it be acidic so you can go straight to the acid, or use water? I was a little confused on that but I get the rest. 2. can you use other things for iodination because I thought it had to I2/CuCl2, does using nitric acid also work? sorry for the weird question, thanks so much for the help
