LABORATORY WORK № 3

Comparison of properties of alkins and arenas.

Objective: To know classification, general formulas,
homology series, isomerism and nomenclature of alkenes
and arenes, electronic structure of ethyne and benzene
molecules, types of hybridization of electron orbitals of the
Carbon atom, orientation of substituents in the benzene
nucleus, laboratory and industrial methods of extraction,
specific physical and chemical properties, their use, genetic
interconnection of hydrocarbons.
To have information about the most widespread means of
protection of nature protection in terms of the use of
representatives of the alkynes and arenas.
To be able to experimentally obtain ethin in the laboratory
and to investigate the chemical properties of ethyne,
benzene and its homologues.
Reagents and equipment: calcium carbide, bromine water,
0.5% solution of potassium permanganate, dilute solution of
sulfate acid, benzene, toluene, 1,2-dimethylbenzene
(o-xylene), test tubes, gas vapor tube, tripod.
