A) if you were to use IR spectroscopy how would you differentiate between acetone, water, and diethyl ether? (include values and relate them to functional groups)

b) you want to carry out chemical reaction that is water sensitive, however the glassware contains salts and you need water to wash them out. the reaction you are going to perform can be done either in acetonitril or toluene. After rinsing out the flask with water, what solvent would you then use to clean the flask: acetonitril, toluene or either of these

c) Someone give you 3 flasks one contains choloform, one is cyclohexane and one is toluene. How can you identify them from physical properties? try to identify them in order give above and do so without using boiling points/distillattion.
