Descriptive Chemistry of Halogens	4a	Light Initiated Bromination of Pentane	Bromine is added to 2 test tubes containing pentane. One tube is masked, and the other irradiated with light. The tube exposed to light looses the bromine color and pH paper shows evolution of an acidic gas.
			Structure of 3 monobrominated isomeric products are shown.
			Mechanism of free radical substitution is shown
	4b	Bromination of Hexane Isomers	Relative rates of reaction of 2 hexane isomers with bromine in light
	4b	Bromination of Hexane Isomers	Mechanism of free radical bromination
	4c	Bromination of Alkyl Benzenes	Bromine is added to benzene, toluene, ethyl benzene, and isopropyl benzene. Order of reactivity parallels the stability of the free radical intermediates.
	4c	Bromination of Alkyl Benzenes	Correlate with 8c -Reaction of Bromine with Benzene, Phenol, and Toluene
	6c	Addition of Iodine to alpha -Pinene - Relief of Ring Strain	reaction of alpha -pinene (from turpentine) with iodine results in a highly exothermic reaction accompanied by a large purple cloud of sublimation of excess iodine
	6c		formerly used to treat infected horses' hooves
	7b	Spontaneous Combustion of Acetylene in Chlorine	Acetylene produced from reaction of calcium carbide and chlorine water bursts into flame and produces a copious amount of soot
	7b	Spontaneous Combustion of Acetylene in Chlorine	Combustion Reaction
	8b	Reaction of Bromine with Cyclohexane, Cyclohexene, and Benzene	Bromine reacts with the double bond of cyclohexene but not with alkanes or aromatic hydrocarbons.
	8b		Addition reaction
	12c	Iodoform test for Methyl Ketones	Methyl ketones react with basic iodine to produce the solid iodoform.
	12c	Iodoform test for Methyl Ketones	Use to illustrate the formation of trihalomethanes during the chlorination of public water supplies containing organic compounds such as humic acids.
	16e	Beilstein Test for Poly(vinyl chloride)	Bottles of poly(ethylene terphthalate) (PET) and poly(vinyl chloride) (PVC) are touched with a hot copper wire which is then placed in the flame of a Bunsen burner. After the wire is touched to the PVC bottle a green flame is produced indicating the presence of chlorine. A colorless flame results after touching the PET bottle.
