Question

Functional group determination can be done with:

• A. \( \text{IR spectroscopy} \)
• B. \( \text{NMR spectroscopy} \)
• C. \( \text{UV spectroscopy} \)
• D. \( \text{Mass spectrometry} \)

Hint:

IR spectroscopy helps identify functional groups based on absorption peaks in characteristic regions of the IR spectrum.

Answer 1

The Correct Option is A

Infrared (IR) spectroscopy is used for functional group determination by analyzing molecular vibrations. Different bonds absorb specific IR frequencies, allowing identification of functional groups like carbonyl, hydroxyl, and amines. This technique is widely utilized in organic chemistry for structural analysis.
