Questions & Step-by-Step Solutions
In infrared spectroscopy, which functional group is typically identified by a strong peak around 1700 cm-1?
Step 1: Understand what infrared 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 common feature in infrared spectra.
Step 4: Identify that this peak is associated with the carbonyl (C=O) functional group.
Step 5: Conclude that the strong peak around 1700 cm-1 indicates the presence of ketones, which contain the carbonyl group.
