Nelson chemistry

[khalil]

I was looking through a pile of CD's and found out that i had the Nelson CHemistry CD.
I put the CD in my computer and discovered there a lot of questions on infrared and NMR spectroscopy. I was so excited.
But I went to the 'answers' section of the book and discovered there were no answers for section 5.7 except for question 3.

What's the point of doing the questions you don't know whether the answer is right or not?

So my question is: Do the answers exist? If they do, then where are they and how can i get a copy of one?

Thanks

I'm not sure as I've never used Nelson Chemistry but would you mind uploading the textbook for us all?
Thanks.

i would but i dont know how

ok, here are some quickly produced answers

1a TMS

1b  peak 1 OH
     peak 2 CH2
     peak 3 CH3

1c ratio of peak heights corresponds to the ratio of number of protons

2  the closer the proton in to the electronegative O the further downfield it shifts

    peak at ~5.8 singlet, OH proton shielded by O => no splitting
    peak at ~3.7 quartet, 3 equivalent neighbours (CH3) => n+1 = 4
    peak at ~1.2 triplet, 2 equivalent neighbours (CH2) => n+1 = 3

3 on CD

4a  because it has a single charged, spinning proton which creates its own tiny magnetic field

4b  resonance frequency energy falls within the radiowave frequency range => proton can absorb the right amount of energy to spin flip

4c  because nearby electrons can shield the effect of the external magnetic field

4d  so that the solvent doesn't produce any peaks that could interfere with the sample you are testing

4e  because of its prevalence in organic compounds and that >99% of H is 1H

5a  beacuse if a protein can't be crystallised its structure can be determined by NMR

5b  Iron is itself magnetic => will interfere with the technique

Yes they exist in the teacher's CD, which I do not have.

i would but i dont know how

Enter the CD and there should be a heap of files. Find the ones that are, I assume, in .pdf with what should be obvious filenames like ch1.pdf or part1.pdf

Zip it up so it's all in one file and upload it to www.sharebee.com

Thanks man

Thanks Chem nerd, how do u know all this stuff?
