Thanks everyone. With your suggestions I eventually determined, in relation to what the assigned reading was for the Unit, that the reaction they were "implying" to happen was an elimination reaction like this... OH H H H | acid | | |...

Hello, I came across this quetion... Complete and balance the following reactions: OH | CH3-CH2-CH2-CH-CH3 -> Now, I don't know if I've gone crazy or something, but what's supposed to happen to that? Its a simple alcohol (2-pentanol) standing there all...

That it does not specify. Sorry. I'm in Chem 20 and currently completing the Unit on Organic Halides and Hydrocarbon Reactions. What I posted is what the question completely is. I'm thinking, since I'm just beginning to learn organic chemistry, that the most simple assumption would be the...

Hello, I know I should have knowledge of this, but I can't seem to remember very well what happens in combustion reactions with a very short supply, limited supply, and abundant supply of oxygen. What is the difference? I know complete combustion hands down, but what happens in a problem such...

Yes that does. Thank-you. I didn't know it was significant if the branches were on the first/last carbon atoms. That clears up my confusion. :smile:

Indeed. For example, in music, the "smartest" musical being is DEFINITELY not famous. Such as in East India, there music takes skill and talent far surpassing western music's requirements. None of us will probably ever know who the smartest person is in anyone area. But, none the less it sure is...

*yawn* I get up at 3:00 am to go to work. The bad part is, I can't fall asleep until 11:00 pm so I end up feeling like this -->[zz)] at 10:00 in the morning. My biological clock makes about as much sense as working the early morning shift Heh. But, such is life... I guess. BTW - Flood-lights...

Hello, I was quite curious about this one here... If I were asked to draw a structural diagram, for example, of trimethylbutane, where would I put the three branches of methyl. When they don't specify the location of the branches what does one do? I'd normally be expecting something like...

Excellent. Thanks so much for your help. If I encounter any more problems in this area I'll be sure to post them in this thread again. Thank-you!

Hmmm. Well, going piece by piece here, I think I understand how you came to making a dot diagram of nitrogen tri-iodide. It would end up looking something like this... correct? .. .. .. :I : N : I : .. .. .. :I : .. ...and the CO2 example would end up looking like...

Hello, I was hoping someone here might be able to explain to me how to determine electron dot diagrams and structural formulas of diatomic/polyatomic elements and compounds. For example... Nitrogen Tri-iodide ( NI3 ) I know the basics of electron dot structures, but when the atoms start...

Thanks so much for your wonderful responses. I think I get it all completely now. Your help has been appreciated. :smile:

Ahhh, I get it. Alright, I understand everything up until this line... O2 + 4Li + 4e- ---> 2O (2-) + 4Li (1+) + 4e- Why does the 4e- still remain in the products and then disappear afterwards? Thank-you.

Hmmm... *reads over information* It somewhat does. I have a question... can you explain this line and how you got to it... 4Li + O2 --->2Li2O Normally I would see Li and 02 occurring together like so... Li2O (lithium oxide). In this case I'm stumped. I have a hunch it has to do with the...

Hello, I was curious if anyone could explain to me the simple procedure/guidleines to carrying out oxidation (half-reactions), reduction (half-reactions) and overall net reactions. I've read my Chem book over and over, but I don't quite understand it. Even a pointer to a good site with a...
