Ok,
the first week of classes is open,
There is 3 lectures worth of work,
So get those pencils going,
I have been finding heaps of good sites, for reference,
So there is no excuse, about getting a bad mark,
This lecturer,me, doesn't even mid if your a bit late,

I am putting up the first lot of homework now, so be sure to give it your best shot

p.s. if you like orbitals, which wwill be explained 3 rd week,
Here's a good link

Where did you get that list.
I would like to review SN1 and SN2 reactions and crossed aldol reactions.
Could anyone post some info about it or give a link where there is good info about it because I have got a test about those things next week.
About sn1 and sn2 reaction, about aldol crossed aldol and about R and S configuration and ee configuration optical configuration...

icecool this list is taken from info file of the cd

that's cool, you able to make ISO images?

Alice · Fri Mar 25, 2005 4:15 pm

sure
already did
looking some public place to upload it
need 250 mb of web-space

Guest · Sat Mar 26, 2005 4:41 am

We have the space,

pm me,
An that can go into our superuser stuff,

wow looks like i found this site just in time to go thru this...
what an awesome idea, well done all! Cool

I am currently doing Environmental science and didnt study chemistry past year 11 so i know the real basics (at least that which has managed to stay inside an active part of my brain), however i will be studying chemistry as part of my Herbal Therapies degree which i hope to be starting next year so this will be an awesome intro.. ill try to keep up,
peace, and nice site, i look forward to contributing to the tryptamine and phenethylamine pages once im back in action. Twisted Evil

Thanks Synthetikal....this is something I think will be very interesting and unique--a free education....and its not a simple subject either. I am looking forward to following along with diligence.

I took two semesters (with two labs) of organic chemistry in college (this is 15 years ago) on my way to what I hoped would be medical school. [Unfortunately, the typical university distractions changed my course and now, strangely enough, I am a lawyer]

While I got Bs in just about every one of the 4 courses (2 classes + 2 labs), my main problem was that I approached the subject like I did most other subjects--by attempting to memorize more then comprehensively understand what was taking place.

For about the last 3 years, I have been trying to re-acquant myself with organic chemistry--although somewhat in an erratic fashion. And while trying to relearn it, though I quickly recalled many of the reactions I tried so hard to memorize (e.g., nucleophilic/electrophilic additions and eliminations), I realized that my problem in college was that I gave the least amount of my attention to the first month of my first semester...valency and electron transfer...so as you can guess, this made the subject inordinately hard to master.

About a month ago, I purchased a copy of Morrison & Boyd's Organic Chemistry (6th ed) and am trying to start over (once again) at square one. I can see now that some of the complexities in sp hybridization theories and dipole movement, etc. are what caused me to gloss over it the first time around.

I look forward to relearning this fascinating subject the right way now--15 years later and would like very much to be an active participant, working along with you and everyone else as I am sure I will have some questions.

I will PM you about the ISO, since I think understanding valency in the most effective way is with some sort of visual/audio tool.

Thanks again!!

That is a good way to start,
The book i use is kotx, and triecal? 5th edition,
If you were to read, and answer all the questions from start to finish,
slowly, of course, you would know as much as anyone that has done a degree, often those books can go into even more detail,

Yes, if you can find a book, that say, a university is offerering in the syllabus,
then that is essentially the books that if learnt, would solve any questions,

The Kotz, book i am working through is brilliant, he was a passionate man, and a great teacher, everything is explained in great detail,
It is a work of art,
It is mentioned in my online lecture notes,

Does anyone happen to have a site about SN1, SN2, E1 and E2 reactions?
I already know this:

1*Rx with a strong base is an Sn2 reaction
1*Rx with bulky base is an E2 reaction
3*Rx with strong base is E1 reaction
3*Rx with weak base is Sn1
3*Rx with bulky base is Sn1
And a 2*Rx depends on the temperature and the concentration.
Exept in a protic solvent the concentration doesn't matter since it will be Sn1 anyway.
For a aprotic solvent Sn2 will occur and when you have twice as concentrated base the reaction will go twice as fast.
Does anyone have some more info on the temperature what will happen than?

There are some fine text books over at the reference section I liked McMurry when I started my re-eduction after decades since I visited a classroom, also Morrison&Boyd , although not yet available in the reference section and if you really feel good read March's text, the 5th edition is available.........remember to contribute to our fine library with your e-books, because the one that benefits is you...............java
