Analyze the data given in each of the problems below, deduce the
structure and give the name.
A fishy-smelling liquid with elemental analysis of C=68.93%, H= 15.04%
and N=16.08%. The Infrared Spectrum has a characteristic weak double
peak at 3300 cm-1 (3.0 µm), and the 1H-NMR shows resonance peaks at
0.8(s,9), 1.1 (s,2), and 2.3 (s,2)ppm.
Okay well obviously I know that the atoms in this molecule are only
carbon, hydrogen and nitrogen. If the infrared has a weak double peak
at 3300 then I know that it is probably going to be an amine and a
primary amine to be exact. Since the percentages of carbon are 68.93% I
assume that there are at least six because its molecular weight is
approximately 12.01 amu, for H there are at least 15 hydrogens and there
are at most 1 nitrogen atoms. The only thing that is stumping me is the
1H-NMR resonance peaks. My molecular looks like this
CH3(CH2)5NH2
And the name of the compound would be 1-hexamine, but I don’t think
this right because of the 1H spectrum.
