Updated On: Jun 16, 2025
- 100–500 cm\(^{-1}\)
- 500–1500 cm\(^{-1}\)
- 1700–2000 cm\(^{-1}\)
- 400–800 cm\(^{-1}\)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The fingerprint region in IR spectroscopy lies in the range of 500–1500 cm\(^{-1}\). This region contains complex absorption patterns unique to each compound, which helps in compound identification.
