Questions & Step-by-Step Solutions
In IR spectroscopy, which bond typically shows a strong absorption around 3300 cm-1?
Step 1: Understand what IR spectroscopy is. It is a technique used to identify different chemical bonds in a molecule by measuring how they absorb infrared light.
Step 2: Know that different types of bonds absorb infrared light at different wavelengths, measured in cm-1.
Step 3: Recognize that the O-H bond, which is found in alcohols and carboxylic acids, is one type of bond that absorbs infrared light.
Step 4: Learn that the O-H bond typically shows a strong absorption around 3300 cm-1. This means that when you see a peak at this value in an IR spectrum, it likely indicates the presence of an O-H bond.
Step 5: Remember that the reason for this strong absorption is due to the stretching vibration of the O-H bond when it is exposed to infrared light.
