explain how infra-red spectroscopy can distinquish between acetone and ethanol.
IR vibrational frequency spectrum shows different frequencies are:
CO functional group in acetone shows IR frequency at 1715cm-1. and alcohol functional group in ethanol shows IR stretching frequency at 3600 cm-1.
explain how infra-red spectroscopy can distinquish between acetone and ethanol.
How can you use IR spectroscopy and UV spectroscopy to distinguish between o-xylene and p-xylene? Please explain how you get the IR values.
Describe with appropriate diagrams, the concept of Raman scattering spectroscopy. Name 2 primary differences between Raman and Infra-red spectroscopy. What is the fundamental property of a molecule that is probed by Raman scattering? [6 Marks]
How can you separate a mixture of ethanol and acetone besides doing a distillation?
(i) Describe with appropriate diagrams, the concept of Raman scattering spectroscopy. Name 2 primary differences between Raman and Infra-red spectroscopy. What is the fundamental property of a molecule that is probed by Raman scattering? [6 Marks] (ii) What are the three possible deviations from the Beer Lambert law? Explain why they might arise. Give an example using chemical equations of a deviation in the Beer Lambert Law due to a chemical shift. [
Which subtrate produces NADH the fastest between Ethanol, Methanol, Isopropanol and Acetone? What does this imply about how well each substrate binds to the enzyme ADH?

How can IR spectroscopy distinguish between: a. diethyl amine and butyl amine b. pentanoic acid and methyl butanote
Can anyone explain this: H2O and acetone are miscible, acetone and hexane are miscible, but water and hexane are immiscible
ii) (4 marks) Briefly explain how 1H-NMR spectroscopy would allow you to distinguish between the 3 isomers of butyl alcohol. MOH LOH
List the three solvents, ethanol water and acetone in order of increasing solvolytic power. is this the order (of polarity) you would expect based on the mechanism of the SN1 reactions? explain.
