Questions & Step-by-Step Solutions

What does the term 'chromophore' refer to in UV-Vis spectroscopy?
  • Step 1: Understand that a chromophore is a part of a molecule.
  • Step 2: Know that this part is responsible for the color of the molecule.
  • Step 3: Learn that chromophores absorb light in the UV-Vis region, which is a part of the light spectrum.
  • Step 4: Realize that when light is absorbed by the chromophore, it can cause the molecule to appear colored.
