I have tried to work out the following problem. Attached to this is a file that show NMR, IR and Mass spec info. I have come up with what I think the compound is but it does not work because the formula has more than one o. I have circled the carbonyl peak as well as the sp3 C-H peak.
See the attachment please.
The first thing you must do when trying to find the structure from an NMR, or IR, is to calculate the degrees pf unsaturation. Thus,
Degrees of Unsaturation =# Carbons - (# Hydrogens + Halogens)/2 + (# Nitrogens)/2 + 1
= 6 - (12+0)/2 + ...
The solution is in the attachment, given as a 200-250 word explanation with equations.
