Chemical nomenclature question

[Chaotic42]

I'm trying to learn a little about naming chemicals. My organic chem book isn't in yet, and I'm not patient when it comes to learning.

Anyway, my conclusion is that this should be named trans-2,3,7,8-dichlorodifluorodibenzo-p-dioxin. Is that correct? If not, why?

man... i use to know how to do these back in my organic days... good luck

you know, they prolly have a short name for it lol.

Oh, yeah. I'm sure. I don't even know if it exists.

I just picked something weird to see if I could get it right.

If your orgo class is anything like mine naming will not be a huge part of the course. There are more intresting things in orgo to read about.

I think you're confusing interesting with boring.

Ahhh, the googles they do nothing...

Well, I'm not in organic chem. I've got another two semesters before it's even an option, and even then I'm not sure if I have room to take it. It's just something I'm interested in.

Not really, im saying there are other subjects in organic chemistry that are more interesting than nomenclature. Whether those things are interesting in relation to other subjects or activities is not the issue here.

I do not think that is right because having 2,3,7,8-dichlorodifluoro. . . doesn't tell you exactly what it is. It would have to be something like 1,7-difluro, 2,8-dichloro . . . which will tell you exactly where the F and Cl needs to be. In your name you couldn't tell exactly where the two flourines and two chlorines are supposed to be amongst the 2,3,7,8.

I am not sure on the rest of the name off the top of my head. I do have a NIST database naming program thing and I will see what info that gives me.

I had organic chemistry in '83 that was quit a few bongs ago 😉

Sorry, organic leaves a bitter taste in my mouth. It was the lowest grade I've had in college.

Doh just noticed that you did use 'trans' in your name, so maybe that is right. The thing in the middle, the two benzen rings connected with oxygen is just dibenzodioxin.

Isn't it p-dioxin because there are two oxygens parallel to each other joining the benzene rings?

Damn I thought organic Chemistry was easy...I got a 4.0 in it and I was stoned to the bone 😉

Why wouldn't a druggie be interested in organic?

A little battery acid, some Sudafed... 😉

You're trying to make me remember things that I took 6+ years ago!!!

Yeah, you know what I think that is 'technically' correct to have dibenzo-p-dioxin, but the common name is dibenzodioxin. So I guess to play it safe you should have dibenzo-p-dioxin.

If I remember right that is the only way you can have that compound (due to the aromatic rings), so the "p" is redundant hence why a common name is dibenzodioxin.

it all depends on the school and the competition for grades there

I'm that guy in class who asks obscure questions and pisses the class off. 😛

UW-Madison good enough for you? I was stuck in a class with a shatload od stuck up pre-med students.

I have no idea, im just saying classes in college are always relative to the students taking the course.

I had a 3.0 in it, but I've have already been accepted into Vanderbilt med school. Now who's e-penis is larger. 😛

Ok I have been bitchslapped 😉

I was majoring in Chemical Engineering and Madison was in the top ten back then.

Arrgh, I give up. I think your prof gave you an imaginary chemical!
I have this NIST database that damn well has every compound that can be put through a GC/MS system. Many tens of thousands of chemicals. Anyhow, typing in the formula I did not get a single hit for it!

If you took away the fluorine and just had 2 chlorines I did find that it was called: 2,7-dichlorodibenzo-p-dioxin

Therefore if you wanted to throw in the fluorine just put them were appropiate which I *think* would be like: 2,7-dichloro-3,8-difluorodibenzo-p-dioxin

I do not think trans would work because trans could imply that the Cl and F could go at the top (or bottom) of the 'apex' of the benzene. Then again if you do have the carbon position number things it may work.
When I looked up the dichlorodibenzodioxin in my NIST database, it did not mention "trans" in the name and usually the program has just about every possible synonyms for a compound.
