Every video of yours is so helpful and concise, I seriously look forward to each one! A video on circuits and/or fluids would be super helpful too, thank you so much for these!
I'm so glad you're finding them useful for your prep! I will definitely put both topics on my list - I have a video on Archimedes' Principle coming out soon, so stay tuned!
redox and substitutions tend to come up the most on the AAMC materials, so that's why I posted videos for both of them! I cover the other reaction types in my course when we cover science passages, since those reactions (like condensation, etc) tend to be tested with as passage-based questions.
Good question! The short answer is that in order to form a double bond between carbon and oxygen, both the carbon and oxygen need to lose a bond to hydrogen so they have the electrons available to form a double bond while maintaining their preferred bonding goals (4 bonds for Carbon, 2 bonds for oxygen). The longer answer gets into the full mechanism of oxidation reactions, which is out of scope of the MCAT; BUT in general you can think about the two hydrogens (the oxygen-hydrogen and the carbon-hydrogen), and realize that the hydrogen bound to the hydrogen is more reactive due to the polarity of the bond, so it will actually leave first with an oxidizing agent present. Then, that negative charge will polarize the carbon-oxygen bond enough to allow the alpha-hydrogen (a hydrogen bound to the carbon next to the oxgen) to leave, re-establishing stability in the form of a C=O bond. Hope this helps!
testing on 8/2 and using these videos as last minute review! Thank you so much!
Glad we could be a part of your study journey! Good luck on your test, and let me know how it goes!
your explainations are amazing. i wish i found this account during my undergrad years
Better late than never! So glad they're useful!

perfect timing thank u! I was just rewatching SN1 SN2 video ◡̈
So glad it helped!
hey these are amazing, can you post some more. I test 9/6 and have been loving these videos.
I try to post weekly!
A video of magnetism would be awesome!!
I'll add it to the list!
could you please go over other rxns ahh

Hello, how come we're losing 2 Hydrogens on our hydroxyl group and from are carbon group instead of just losing it from our carbon group?
