1.1 Problems to solve

• Identify the presence of the main types of hydrocarbon groups (aliphatic, ethylenic, aromatic or acetylenic) and functional groups in the compound under examination.

• Specify the sequence of the various atoms in the skeleton, then determine the location of the functional groups.

• Identify inter- and intramolecular exchange phenomena.

• Examine tautomeric forms.

  At this stage, the molecule's planar structure is established.

• Determine stereochemistry. Two enantiomers give strictly the same NMR...
