Summary
The essence of HNMR (Hydrogen Nuclear Magnetic Resonance) analysis lies in understanding the number of peaks, their integrated area, and peak positions to deduce the structure of organic compounds.
  • The number of peaks in an HNMR spectrum corresponds to the number of chemically different hydrogen nuclei.
  • The integrated area under these peaks represents the relative abundance of these nuclei.
  • Peak positions reveal the chemical environment or shielding of the nuclei, indicating the presence of electron-withdrawing groups.
  • Coupling or splitting occurs when chemically different nuclei on adjacent carbons interfere with each other's peaks.
  • Through a detailed analysis of peak number, area, position, and splitting, one can deduce the structure of compounds, such as identifying 1,1-dichloroethane from its HNMR spectrum.
