Two students are given the starting material benzoic acid and are asked to prepare benzaldehyde. The first student starts by refluxing her sample of benzoic acid in thionyl chloride in the fume hood. Upon completion of the reaction, she evaporates the thionyl chloride to isolate compound A. She treats compound A with a stoichiometric amount of lithium tri-tert-butoxyaluminum hydride at -78 °C in diethyl ether, producing compound B. Adding water, she isolates her product, compound C. The second student takes a different route. She treats benzoic acid with an excess of lithium aluminum hydride (LAH) in diethyl ether, followed by careful addition of ethyl acetate to remove any unreacted LAH. She adds water and isolates her product, compound D. Draw the structure for compound A, compound C, and compound D.

You are given a mixture of benzoic acid, 2-naphthol and 1,4-dimethoxybenzene and you are asked to separate the mixture into its following compounds. You are limited to using dichloromethane, pentane, cyclohexane and ethyl acetate as organic solvents. This doesn't involve solvents used to convert the 3 compounds to ionic salts. Suggest possible organic solvents and explain a procedure you would carry out to separate the 3 mixtures briefly.
When bromomethane undergoes solvolysis in a solvent mixture composed of 90% water/10% acetone, the reaction rate is faster than when the same compound is solvolyzed in 80% water/20% acetone. Explain.

Isoerythrogenic acid, C18H26O2, is an acetylic fatty acid that turns a vivid blue on exposure to UV light. On Catalytic hydrogenation over a palladium catalyst, five molar equivalents of hydrogen are absorbed, and stearic acid, CH3(CH2)16CO2H, is produced. Ozonolysis of isoerythrogenic acid yields the following products: formaldehyde, CH2O, malonic acid, HO2CCH2CO2H, adipic acid, HO2C(CH2)4CO2H, and the aldehyde carboxylic acid, OHC(CH2)6CO2H. Provide a structure for isoerythrogenic acid.
