Title: Organic question- how to alter an organic compund slightly?
Post by: redbaron on May 24, 2006, 04:44:52 PM
Hello,
We're learning organic chemistry in my chem class, and I have a question on my homework that has stumped me and my friends. It is a replacement reaction, which I haven't learned yet. The question asks how to get 2-methylhexanonitrile from 2-methylhexane. If I am correct, you would start with:
    CH3 H  H  H  H
      |   |   |   |   |
H3C -  C - C - C - C - CH3
      |   |   |   |   |
      H   H  H  H  H

and try to replace the ending CH3 (H3C) with and NC to get something like:
  CH3 H  H  H  H
    |   |   |   |   |
NC -  C - C - C - C - CH3
    |   |   |   |   |
    H   H  H  H  H

But how could you achieve this though without replacing all of the CH3 molecules? Can anyone help?

Check out the heating. However, you won't yield this product only.

That was my first thought too, but as Albert said, it will be messy.

Well, you know, Dan, it's just an exercise, isn't it? We may even use F2.

Ah, thanks for the help- I'll get back to you on what my teacher had in mind.  :)

Yeah I know, I was just agreeing with you, I wasn't criticising you.

Come on, Dan: you didn't get the meaning of my post. I know you weren't criticising me. :)

I just pointed out that, being this a high school exercise only, we should think about the answer just as a possible way of yielding the nitrile.
