I hope you don't mind me copying the relevant parts of your PM to me, but some parts of your PM didn't make sense, and I thought some of the info in it may be helpful to others trying to assist you. In your PM, you say:
unknown A- I think is 1-butanol.
All i know about the formula is that there are 10 H's and a O somewhere.
The Pmr is as follows and the IR is 3420.
1.0 t, 3H
1.5 d, 3H
2.0 m, 2H
3.6 m, 1H
4.4 s, 1H exch.
The compound is clear and forms bubbles which means it is carboxcylic acid.
Stop. You say you think it is 1-butanol, but then say because it forms bubbles it is a carboxcylic acid. 1-butanol is not an carboxcylic acid. Also, what do you mean by the abbreviation "exch." If it is an alcohol, that may possibly be the OH group, and would also explain your IR peak. Last part of your PM...
For compound B I am totally lost. I think the formula is either C8H7ClO or C8H7O.
the PMR is 2.1 s 3H
6.9 - 7.4 4H
IR 1715.
You keep stating what your IR is. I was wondering, do you have a printout from doing an IR scan, or do you just have a list given to you of what peaks are there? If you have an actual scan, can you please list other peaks that are present, especially for compound A. Take a look at
hexanoic acid If you look at the
1H NMR (Which, btw, I've never heard referred to as PMR, *shrug*), and the
IR, you will see the result of a typical alkyl acid. See the big peak in the IR at 1700? Do you have one like that?
There should be more than just the one peaks in the IR, that are noteworthy, so if you have access to them, listing other peaks may be helpful. Or, if you can do even better, and scan them, that works also. More info would be very helpful.
