How do you determine positions

Takron - 18-10-2011 at 18:10

I was curious if anyone had a good online or physical text I could read that gave information on how to determine where on a hydrocarbon ring things will attach to.

For example: If you nitrate a benzene ring, why does it attach to the position it does and how does one determine where other things will attach to similar carbon links?

Not looking for an explanation, just possible texts I could read.

ANY ORGANIC CHEMISTRY TEXT. See directing groups. Try google.

See also, inductive effects and resonance structures.

For the specific example you gave, check the Wikipedia entry for Electrophilic Aromatic Substitution. There is a pretty clear description of directing effects given there. As Ozone says, any basic organic chemistry textbook will give you plenty of additional information - this is one of the major topics in first-year organic chemistry courses in colleges.

As Ozone said, any textbook on basic organic chemistry will explain it to you. A textbook on organic chemistry is an invaluable investment. :)

The attached pdf gives a short introduction to the topic.

Darn it, my connection is too slow at the moment - all my uploads failed. I'll try again later.

Here you go :)

Edit: Wtf, didn't work this time either. I've tried with two different connections now, so I'm betting the problem isn't on my side.

What needed is a Kama Sutra for molecules.
Anyone know where to get a copy?? ;)
