An experiment is described involving the nitration of ortho or meta monosubstituted benzoic acids (XC[subscript 6]H[subscript 4]CO[subscript 2]H, X = Halogen, Me, OH, or OMe) and monochlorinated acetanilides with nitric acid to determine the regioselectivity of addition by [superscript 1]H NMR spectroscopy and molecular modeling. Students were…

The nitration of six benzene derivatives having a range of substituents that differ in electronic effects were followed by GC-MS analyses of the crude reaction mixtures and adapted for the second-year organic laboratory. Students pool their results and identify the products by analyzing the mass spectral data of the isomers and by comparing them…

Reviews the dangers of benzene as a toxin as well as a flammable substance. (CS)

Suggests alternatives for benzene, carbon tetrachloride, and chloroform and offers safety precautions when these solvents must be used. (JN)

Presents cautionary information to science teachers concerning the use of benzene and of Plutonium 239 radioactive sources. (PEB)

Describes an undergraduate chemistry laboratory experiment involving the production of phenol from benzene with the intermediate production of isopropylbenzene and isopropylbenzene hydroperoxide. (SL)

Describes an undergraduate spectroscopy laboratory experiment involving the absorption spectrum of benzene. (SL)

Describes a physical chemistry experiment involving the analysis of the spectrum of benzene vapor in which the resolution in terms of wave length is a limiting factor. (CS)

Describes a lecture demonstration method to illustrate some aspects of the nitration of alkyl benzenes. (SL)

Reports on an organic chemistry laboratory experiment of the bromination and nitration of benzene to illustrate the nature of electrophilic aromatic substitution reactions. (SL)

Describes a laboratory experiment in which benzene fluorescence is quenched by bis(acetylacetonato) copper(II). Discusses how this experiment can demonstrate a special technique used in the field of photochemistry. Provides an outline of the experimental procedure and discusses its results. (TW)

In this experiment, benzylic hydrogen reactivity is used to prepare dimers of a variety of alkyl benzenes, and the benzylic hydrogen reactivity of these compounds are compared. (BB)

This booklet, one of a series of 17 developed at Prince George's Community College, Largo, Maryland, provides an individualized, self-paced undergraduate organic chemistry instruction module designed to augment any course in organic chemistry but particularly those taught using the text "Organic Chemistry" by Morrison and Boyd. The…

Describes exercises using simple ball and stick models which students with no chemistry background can solve in the context of the original discovery. Examples include the tartaric acid and benzene problems. (GS)

Discusses the relationship between adsorption isotherms and elution peak shapes in gas chromatography, and describes a laboratory experiment which involves the adsorption of hexane, cyclohexane, and benzene on alumina at different temperatures. (MLH)
