Answer 1

Answer:

The IR region which is used for establishing the identity of two compounds is a. Far IR region b. Finger print region c.

Answer 2

Answer:

The IR region which is used for establishing the identity of two compounds

is Finger print region.

Explanation:

What is IR region?

• IR region refers to the Infrared Region of the electromagnetic spectrum.
• The range of the IR region is 600-4000 cm-1.

Division of IR region:

IR region is divided into three regions, namely:

1. Near
2. Mid
3. Far

What is Functional group region of IR?

• The region between 1450-4000cm-1.
• It is associated with stretching vibrations of a functional group.
• It consists of few peaks.
• It is used to identify the functional group of the compounds.

What is Fingerprint region?

• The region between cm-1450-500cm-1.
• Associated with the bending vibrations in the molecule.
• It is a complex region having large number of peaks.
• Fingerprint region of each compound is unique therefore it is used to identify two different compounds.
