The naphthalene molecule has a structure that corre-
sponds to two benzene molecules fused together:
The ™ electrons in this molecule are delocalized over the
entire molecule. The wavelength of maximum absorption
in benzene is 255 nm. Will the corresponding wavelength
in naphthalene be shorter or longer than 255 nm?
The infrared spectrum of a compound is unique to the types and number of bonds in the molecule. Draw the structures of salicylic acid and aspirin. What are the key differences of the IR spectrum of aspirin with that of the starting material, salicylic acid? What are the similarities? Interpret the IR spectra of each by assigning the major peaks.
What are 2-3 organic compounds that each contain at least one of the following: carboxylic acid, ester, amine, or amide. How it is synthesized and used, and how the function of the compound is facilitated by its structure and, specifically, its functional groups.

- How to draw the line bond formula or lewis structure of a methyl ketone with the chemical formula C6H5C3H5O? Based on the results of the solubility tests, the compound can be grouped in VI, which is insoluble in water, 10% NaOH and 10% HCl but soluble in concentrated H2SO4. If the compound is water-insoluble but soluble in concentrated H2SO4, it is most probably an alcohol, aldehyde, anhydride, ester, ether, ketone, or an unsaturated hydrocarbon The functional group/class is identified to be Methyl Ketone, base on the results of the chemical tests on Table 2.
