Q: What type of information can be obtained from a UV-Vis spectrum?
Solution: A UV-Vis spectrum can provide information about molecular structure, concentration of absorbing species, and presence of functional groups based on absorbance patterns.
Steps: 5
Step 1: Understand that a UV-Vis spectrum is a graph that shows how much light a substance absorbs at different wavelengths of ultraviolet and visible light.
Step 2: Recognize that the peaks in the spectrum indicate specific wavelengths where the substance absorbs light.
Step 3: Learn that the position of these peaks can give clues about the molecular structure of the substance, such as the types of bonds present.
Step 4: Note that the height or area of the peaks can be used to determine the concentration of the substance in a solution.
Step 5: Identify that certain patterns in the absorbance can indicate the presence of specific functional groups, like alcohols or carbonyls.
