Concept explainers
Interpretation:
The structure of a given molecular formula C8H16 to be predicted using spectrum details.
Concept introduction:
1HNMR : The 1HNMR spectrum gives information on the different electronic environment of protons. The number of signal (proton types) generated in 1HNMR are predicted by performing symmetry operations (rotation or reflection symmetry).
The 13CNMR spectrum gives information on the different electronic environments of carbon. As like 1HNMR, the number of signals generated in 13CNMR are predicted by performing symmetry operations (rotation or reflection symmetry). Only chemical shift values are reported in the spectrum but not the multiplicity and integration values because the coupling between two neighboring 13C - 13C nuclei are weakly involved due to the low abundance of 13C isotopes of carbon atom.
HDI Calculation:
Where
C represent number of carbons.
N represent number of nitrogens.
H represent number of hydrogens.
X represent number of halogens.
