Title: NMR question !
Post by: hyperblade01 on March 27, 2009, 08:04:25 pm

Hey guys, today got a worksheet in class and unfortunately the teacher wasn't able to explain it well.

Basically there's an empty graph and we have to construct the NMR spectrum we would expect for X compound.

It says at the top a method on how to do it:

1. look up the chemical shft, place a line at the approximate value
2. Add the splitting information from adjacent H's
3. Add the intergration trace reflecting the number of H's in the group

I was hoping that someone would be able to explain/draw how 2-propanol and 1-chloro 2 methylpropane would look like on their respective graphs

Thanks in advance :)

Keep in mind that protons closer to electronegative elements (oxygen) are more to the left.
