totally random --- anyone good at Organic Chemsitry?

I need help on my homework its kicking my *kitten*

Help?

Also How can I get an image of the question into here? I don't have flikr or photobucket...

OH i'll add it as a picture of me, it'd probably be too small tho... well help with that too please!

I did take an Organic Chem. class at one point, but I think I barely passed LOL!

If you ever have math/physics questions, give me a shout

Oddly enough, I'm a chemist... While organic wasn't always my fav (I'm more analytical/inorganic), I might be able to help.

im great at organic chem whats the question

Had to re-take orgo 2, so it kinda got drilled into my head, but that was a few years ago and has probably been replaced by other slightly more useful knowledge. But maybe I remember enough to help.

The subject we are on is Alkenes and Alkeynes Addition reactions, that should give you a reference.

We are given hepta-1,6-diene and it reacts with catalytic H+ and I am supposed to guess the two constitutional isomer products

The hints we are given:
Composition of the products is C7H12
Both isomers react with one equiv. of Br2

When's the assignment due? All my organic books are at work...

alecta337

I think the answers are hept-6-en-2-ylium but the composition of that is C7H13!!!!

UGH!!

We are also asked to predict the products if the same reactant reacts with KMnO4, OH-, and heat

Tomorrow morning 11am. I am a true procrastinator =]

Well, I'll check back in the morning at 7:30 ish. If you don't have the answer by then, I'll work on it.

Can you give the actual question as it is written?
I aced organic chem, but I need to know how the question is being asked.... (sort of a quirk, but its the type of thinker I am...)

alecta337

Draw bond-line structures of the products corresponding to each boldfaced letter in the following
reaction sequence. The composition of A and B is C7H12. Both react with only one equiv of Br2.

> A + B (constitutional isomers)

| KMnO4, OH-, heat

C


I need to find products A+B+C

alecta337

In the rxn for C, the fact that there is heat added makes me think its an elimination reaction, We always learned that heat was elimination. And its a small base, so probably E2 right?

My brain hurts... Turns out Orgo has been blocked from my memory. Probably too traumatic.

Yeah I don't blame you. Unfortunately I'll probably need this crap for my career.

I'm going into biomedical engineering. Yay for the hardest major at my school!!!!

definitely agree about elimination rxn...

I am having difficulty recreating the bond diagram (im too much a visual learner that I need the images)
as soon as I get all that straight I will get it....
lol

Thats the picture, except there is another double bond on the other end of the carbon chain also

Im sorry I couldn't get to you,
I kept getting something that didn't quite work out.
Hopefully you were able to figure out the assignment....
