Explain how you would prepare each of the following compounds from benzene:
a. phenol b. o-ethyltoulene c. 3-chloroaniline d. p-nitrobenzoic acid
Starting with butane, explain how you could prepare:
a. 2-bromobutane b. 1-bromobutane Note: for the following targets, you may also choose to begin with either 2-bromobutane or 1-bromobutane as prepared above without repeatedly showing how you made these two compounds Be sure to choose the best starting material for each job. c. 1-butene d. 2-deutrobutane e. 3-methylheptane f. 5-methyl-3-heptyne
