Q: In IR spectroscopy, which functional group is indicated by a strong peak around 1700 cm-1?

Solution: A strong peak around 1700 cm-1 in IR spectroscopy is characteristic of the carbonyl (C=O) functional group.

Steps: 4

Step 1: Understand what IR spectroscopy is. It is a technique used to identify functional groups in molecules by measuring how they absorb infrared light.
Step 2: Know that different functional groups absorb infrared light at specific wavelengths, measured in cm-1.
Step 3: Recognize that a strong peak around 1700 cm-1 is a specific absorption that indicates the presence of a carbonyl group (C=O).
Step 4: Remember that the carbonyl group is found in compounds like ketones, aldehydes, and carboxylic acids.
