A molecular formula constrains composition but can correspond to multiple constitutional or stereochemical structures.
Key ideas and conditions
Structure
A molecular formula constrains composition but can correspond to multiple constitutional or stereochemical structures.
IR evidence
Infrared features reflect vibrational modes and can suggest functional groups. Overlap and context limit one-peak identification.
NMR evidence
Chemical environments influence NMR signals. Symmetry and experimental conditions can change how many distinct signals appear.
Combined reasoning
Use formula, spectra and other evidence together. This paper-based lesson avoids chemical synthesis or hazardous procedures.
Explain without looking
- Describe how to report an uncertain structure assignment honestly.
