Recall IR spectra range for functional groups:

  1. Ether (C-O-C): 1000-1300 cm-1
  2. Aldehyde 
    • -C=O: ~1720-1740 cm-1
    • -C-H: 2700-2800 and 2800-2900 cm-1
  3. Alcohol (-OH): ~3200-3600 cm-1
  4. Carboxylic acid (C=O stretch): 2500-3000 cm-1 (broad)
  5. Alkane
    • C- H: 2850- 2990 cm-1
  6. Alkene:
    • C=C: ~ 1630-1680 cm-1
    • C- H: 3000-3100 cm-1
  7. Benzene:
    • C-C: ~1600 and ~1500cm-1
