Organic demonstrations have been used less frequently than those involving inorganic chemistry because of safety hazards, expense, and availability of reagents, and visibility of the reactions. The videodisc overcomes these problems and also allows slow reactions to be compressed to a few minutes of video.
Users of this videodisc will find that by providing a single viewpoint that applies to everyone in the audience it makes clear a number of points that are difficult to get across in a typical lecture. For example, the relationship between molecular structure and a projection formula is nicely shown by using a light source to project a shadow of a molecular model onto paper and then drawing a projection formula on the paper with the model still present.
In addition, the disc contains a large number of organic reactions presented in an interesting, visual manner. Photochemistry and the rotation of plane-polarized light by chiral molecules are shown clearly, as are laboratory techniques.
Teachers of introductory courses will also find this disc very useful, because it shows many demonstrations commonly done at that level that involve hazardous materials or uncommon apparatus or substances. Examples are combustion of methane/oxygen mixtures, conformations of alkanes, relationship between structure (intermolecular forces) and boiling points, chromic acid oxidations, chemiluminescence, silver mirror--Tollens Test, reactions and pH of organic acids and bases, effect of pH on proteins, dyes and dyeing, and polymers.
Hardware and Software Requirements
"Demonstrations in Organic Chemistry" is a 12-in., double-sided, 60-minute, CAV-type videodisc in NTSC format (it is incompatible with the PAL standard used in many European countries). It may be operated from any videodisc player using a hand-held remote-control keypad or a barcode reader.
To make the video presentation visible to students in a classroom either a large-screen color monitor or a color video projection unit will be needed. The size of the monitor (or the need for a projection unit) depends on the size of the class to which the presentation will be made.
