Q: What does the peak position in an IR spectrum indicate?
Solution: The peak position in an IR spectrum corresponds to specific functional groups, allowing identification of the types of bonds present in the molecule.
Steps: 5
Step 1: Understand that an IR spectrum is a graph that shows how a molecule interacts with infrared light.
Step 2: Recognize that different parts of the spectrum correspond to different types of bonds in a molecule.
Step 3: Learn that the position of a peak on the spectrum (measured in wavenumbers, usually in cm^-1) indicates the type of bond or functional group present.
Step 4: Use reference tables to match the peak position to specific functional groups (like -OH, -NH, -C=O, etc.).
Step 5: Conclude that by knowing the peak positions, you can identify what types of bonds are in the molecule.
