Correct name for the given compound has to be given and the condensed structural formula for the same has to be redrawn. Concept Introduction: Any organic molecule can be named by using certain rules given by IUPAC (International Union for Pure and applied chemistry). IUPAC name consists of three parts in major namely Prefix suffix and root word. Prefix represents the substituent present in the molecule and its position in the root name. Suffix denotes the presence of functional group if any in the molecule. It can be an alkene , alkyne , alcohol, carboxylic acid , alcohol etc... Root word represents the longest continuous carbon skeleton of the organic molecule. To Identify and Draw: The correct IUPAC name for the compound and redraw the condensed structural formula.

Question

Wintergreen from Aspirin: 1. In isolating the salicylic acid, why is it important to press out as much of the water as possible? 2. Write the mechanism of the esterification reaction you did. 3. What characteristic absorption band changes would you expect in the IR spectrum on going from aspirin to salicyclic acid and then to methyl salicylate as you did in the experiment today? Give approximate wavenumbers associated with each functional group change. What signals appeared/disappeared/shifted that indicate that you have your intended product and not starting material? What other impurities are present in your product and how do you know?
