Questions & Step-by-Step Solutions

Which of the following is a common application of infrared (IR) spectroscopy?
  • Step 1: Understand what infrared (IR) spectroscopy is. It is a technique that uses infrared light to analyze substances.
  • Step 2: Learn that IR spectroscopy measures how much infrared light is absorbed by a sample.
  • Step 3: Know that different chemical bonds absorb infrared light at different specific wavelengths.
  • Step 4: Realize that by measuring these absorptions, we can identify the functional groups (like -OH, -NH2, -COOH) present in organic compounds.
  • Step 5: Conclude that a common application of IR spectroscopy is to identify these functional groups in organic compounds.
