Is there a good website for naming of stuff?

I get so confused when they randomly go from Isopentane to ter-Butyl. I have no idea how to write out the structure...

I know there is a pattern but I can't see it 🙁

Yeah it can be really confusing when you first start out (and the tert stuff is especially confusing - it's all just structural). To be honest ... I usually just wikipedia/google stuff. Like I just type stuff into google and usually wiki is the first result with a break down on what I need. Don't use it like the bible, but it can usually get you past an annoying point you can't get over to continue ... an activation energy, if you will

tert butyl is just a tertiary carbon...(3 carbons attached to central carbon)..to go from isopentane to tert butyl there must be bond breaking.

Also use the search function. There are lots of O-Chem threads.

Some of the non-IUPAC names you just have to memorize; even then, there are patterns.

n-alkane= straight chain alkane
isoalkane= straight chain with one methyl branch
neoalkane=straight chain with two methyl branches

sec/tert (or secondary/tertiary) simply tell you how many carbons the first carbon is attached to at the point of attachment in an alkyl group. You've just gotta be able to recognize what the letters or prefixes mean.

Ohhhh, I never knew that.




OP, just wait till you get to the reactions.... I've got 104 reactions to memorize for the Orgo II midterm. The number will double by the time of the final.👍 And I hear biochem is worse.....

I would help you out, but after I got done with that course I went straight to my schools bookstore and sold that book for every single penny I could get back.

there's a book called organic chemistry I as a second language by klein (sp?) that's supposedly really helpful for ochem in general.

i flipped through it at a local bookstore and i must say, i was impressed. not exactly a textbook replacement but good nonetheless. only 30 bucks.

actually, biochem is memorizing/understanding a whole bunch of rxns and mechanisms but not like ochem where you have to apply those reactions to synthesize something. so it's more like biology where you just understand/memorize instead of trying to apply what you know to a problem.

thanks for all the advice guys! This subject is killing me 🙁
