Anyone take organic chemistry lately have links to lectures notes I can see?

Members don't see this ad.

I want to kind of compare what was taught in my semester of organic chem 1 versus what your school did

Our prof didn't go over alkynes and the various reactions, we only mainly went to alkenes with the various configurations and reactions

sooo i'm wondering if ill be hurt on the ASCE exam at the end of organic 2

Alkynes don't do very much. If they're primary they can be deprotonated in very strong base and act as a nucleophile to bond with alkyl halides, but that's about the only unique reaction they do. Otherwise you can treat them just like alkenes. For example, add one equivalent of Br2 to ethyne and you get 1,2 dibromoethene. Add a second equivalent and you get 1,1,2,2 tetrabromoethane. It's the same reaction, only with an extra step to convert the alkyne into an alkene.

PM me with your email and I'll send you a copy of my professor's lecture notes on alkynes if you want. He did a good job teaching the class.

Except if you want to turn an alkyne into an alkene. That may show up... hint hint... just took acs final

Wait, orgo profs are supposed to teach?

Here are the alkynes we covered in Orgo 1:

Alkyne --> Alkane via H2 gas/ Pd/C
Alkyne --> E alkene via Na/NH3(l), works for internal alkynes only
Alkyne --> Z alkene via Lindlar or poisoned catalyst (H2/Lindlar)
Alkyne --> acetylide ion, Na, NH2/NH3(l), aka dissolving metal reduction - useful for opening epoxides and generally acting like a very strong base
Alkyne --> Carboxylic Acid via Hg(OAc)2/H3O+
Alkyne --> Aldehyde via 1) 9BBN 2) H2O2, NaOH

Definitely get the review book for the national exam, and go through that to see what it'll be like.

Part 2 is on ITunes U

MIT posts notes, homework, tests, and answers online as part of an open courseware initiative.....

might be helpful. I doubt the subjects have changed much since they were posted
