The 3200-3500 cm-1 region can be used to distinguish between alcohols and amines by frequency alone. Question 9Select one: True False

Analyzing the Statement

1. Understanding the Functional Groups:

   • Alcohols generally have OH (hydroxyl) groups.
   • Amines possess NH (amino) groups.

2. Infrared Spectroscopy:

   • The region 3200-3500 cm^-1 in an IR spectrum is typically associated with O-H stretching of alcohols and N-H stretching of amines.

3. Frequency Overlap:

   • Both alcohols and amines can absorb in this range, but their absorption peaks might be slightly different, with alcohols usually showing broader peaks compared to the sharper peaks of amines.

Conclusion

• While there is a difference in the peaks that can help distinguish alcohols from amines, using frequency alone in the 3200-3500 cm^-1 region may not be sufficient due to the overlap in absorption characteristics.

Final Answer

False. The 3200-3500 cm^-1 region cannot distinctly be used to differentiate alcohols from amines by frequency alone due to the overlapping absorption bands.
