11.1 Introduction to Organic Synthesis | Retrosynthesis | Organic Chemistry

Chad provides an introduction to Organic Synthesis (Retrosynthesis), one of the more difficult types of questions appearing on Organic Chemistry exams (particularly in 2nd semester). Chad outlines five important functional group conversions that should be familiar to the undergraduate at this point in the curriculum giving a framework for how to organize the set of organic reactions in one's memory. He then moves on to show how to increase and decrease the length of the carbon chain and the one type of reaction that can be used to open up a ring in the carbon chain.

Thank you sir. I haven't taken og chem yet but your prep is so nicely comprehendible.
I think I am going to look through your series to give me a jump on the subject, I really appreciate you making these :) !

what chapters is the last reaction in 9:00 from

[aszasq]

sir, at 17:30 wouldn't the acetylide ion be more attracted to the secondary carbon since it have more positive charge? why would it be different than the oxymercuration demercuration reaction?

Chad never tell someone how to think unless you want 🤖 robots . Remember that science has not been fully worked out completely, I only know this because we rely on explosions and consuming way too much to get minuscule distances . So unless you can figure out how to carve perfectly symmetric masterpieces with materials harder than diamond, or have a back of copies of the scrolls burnt up in the library of Alexander, then I think you don't have what it takes to be the one to tell me how use my brain .
