Answer 2

The presence of a functional group in a compound can be established by using IR spectroscopy.

Explanation:

• The presence of functional group  is determined using IR spectroscopy.
• IR spectroscopy or infra red spectroscopy is the branch of spectroscopy which deals with the infra red region of the electromagnetic spectrum.
• In this the light with a longer wavelength and lower frequency than the visible light is used.
• In this technique, the basis is on absorption spectroscopy.
• Here In IR spectroscopy, the measurement of the interaction of infrared radiation with the matter takes place by absorption,emission and reflection.
• This spectroscopy is used to identify and study the functional groups in solid,liquid and gaseous form.
