Solution

Difference between functional group region and fingerprint region in an infrared spectrum:-
FUNCTIONAL GROUP
FINGERPRINT GROUP
The range of the Infrared spectrum is 4000 ${cm}^{- 1}$ to 1450 ${cm}^{- 1}$ .
The range of the Infrared spectrum is 1450 ${cm}^{- 1}$ to 500 ${cm}^{- 1}$ .
The spectrum contains stretched vibrations.
The spectrum contains bend vibrations.
The pattern of peaks is simple.
The pattern of peaks is complicated.
These are characteristics of specific kinds of bonds.
These are characteristic of molecular symmetry or combination bands from multiple bonds.
The left side of the image is the Functional group region of propan-1-ol ( ${CH}_{3} {CH}_{2} {CH}_{2} OH$ )
The right side of the image is the Fingerprint region of propan-1-ol ( ${CH}_{3} {CH}_{2} {CH}_{2} OH$ ).
