Physical Properties	3a-d	Relationship of Structure to Boiling Point of Alkanes	Shows boiling boint of straight chain alkanes containing 5 to 10 carbon atoms
			Shows boiling point of 5 isomers of C6H14
			Data can be graphed to illustrate effect of Van der Waals attraction on boiling point

	9b	Polarized Light and Organic Molecules	Demonstration of polarized filters and polarimeter
			When plane polarized white light is passed through a cylinder of aqueous sucrose, a spiral rainbow of color is observed
			Rainbow images of plastic objects under polarized light
			Polarization of liquid crystal display of a calculator
	16c	High and Low Density Polyethylene	Samples of high density polyethylene (from a milk bottle) and low density polyethylene (from a squeeze bottle) are separated by placing them in aqueous ethanol. The high density sample sinks, and the low density sample floats.
