How can we use UV-Vis spectroscopy to identify the presence of specific functional groups (such as carbonyl, aromatic, or alcohol groups) in a given compound? Can we determine the concentration of these functional groups using UV-Vis spectroscopy? How can we compare the UV-Vis spectra of different functional groups in order to distinguish them from one another?

How can Raman spectroscopy be used to determine the presence of a specific compound in a mixture of similar compounds? Specifically, how can the unique Raman spectra of the target compound be identified and distinguished from those of other compounds in the mixture, and what is the minimum concentration of the target compound that can be detected using this technique?

A chemical engineer needs to separate a mixture of ethanol and water using a distillation column. The feed to the column has 30 mol% ethanol and 70 mol% water, and the desired distillate composition is 95 mol% ethanol. The feed rate is 100 kmol/hour and the reflux ratio is 2. Calculate the number of theoretical trays required in the column to achieve the desired distillate composition.
