Questions & Step-by-Step Solutions

What type of information can be obtained from the IR spectrum of a compound?
  • Step 1: Understand that IR spectroscopy is a technique used to identify different functional groups in a compound.
  • Step 2: Know that functional groups are specific groups of atoms that determine the chemical properties of a compound.
  • Step 3: Learn that when a compound is exposed to infrared light, it absorbs certain wavelengths of that light.
  • Step 4: Recognize that each functional group has a unique pattern of absorption, known as absorption bands.
  • Step 5: Analyze the IR spectrum to identify these absorption bands, which correspond to specific functional groups.
  • Step 6: Conclude that by examining the IR spectrum, you can determine what functional groups are present in the compound.
