I will help you out later on today if someone doesn't beat me to it. If I forget, shoot me a PM in a couple of hours. I am currently at work.

 

ok thanks

 

Are these supposed to be redox reactions?

The first one looks like a Reduction reaction; it converts from Cyclohexanone -> Cyclohexanol (OH, not =O)

Second appears to be the opposite (an Oxidation Reaction); Your Hydroxyl group on your Carboxyl Group at the end will lose it's "H" from the Hydroxyl and gain an electron.

The third is a matter of kinetics. Whichever bond has the weakest "link" will break off. In this case it will be your Carboxyl Group - if I remember correctly. If you ask why this happens, it's because of the EWGs and EDGs. The oxygens on your Carboxyl group are extremely strong EWGs making the C-C bond much weaker. When heated to a certain temperature they will break (before any of the other bonds will). Let me see if I can find my notes for all of this from last semester - Looks like Org. II.

Or Heads can correct me later if he gets around to it.

 

thanks i pmed both of you and it is orgo II. have a couple others i need to check if you have the time.

 

I'm pretty sure szskateman22 got it right on the first two. And I don't know about the last one because I don't really understand it either lol. You might wanna PM Sypherz also--I think he's also pretty good with this.

And you said you had others that you wanted to check?

 

Can you draw out the products for any of these as well?

please excuse how sloppy they look...I made them with paint -_-

 

Try this program: http://www.acdlabs.com/resources/freeware/chemsketch/

It's the "free version" of a program known as ChemDraw - used by professionals. It should make everything a little more neat for you.

As of now, I will look into the files tomorrow. I thought I had some on my computer, but I was mistaken (then again it is 1 A.M.). I will skim through my notes tomorrow and help you out from there. If I run across my professor's notes in the process I will scan them in as well and let you look at those. ^_^

 

Sorry for the late response. Been very busy lately.

Check your pm

 

Could you zoom in on the 4 problems please? It's difficult to see them. >_<

Also, could you tell me what you are up to in Org. II? Diels-Alder yet? Dienes? If you can provide me that I can help even quicker.

 

Ill pm you a more zoomed in version now

 

I think Heads has it right... Sort of too lazy to check right now. =|
