"Demonstrations in Organic Chemistry" is a videodisc designed to provide visual examples of the chemistry of carbon compounds. These demonstrations are intended to increase student interest and learning by seeing chemical phenomena before analyzing them at the molecular level. The content of this videodisc is designed for use at both the high school and college level in general and organic chemistry courses. Many demonstrations include practical examples of the chemistry of fuels, food, drugs, dyes, and polymers. Techniques such as the use of the separatory funnel in extraction of an acid and thin layer chromatography of a dye mixture are shown. In addition to chemical demonstrations, some segments show the use and manipulation of models of organic molecules including conformations of alkanes and cycloalkanes, enantiomers, and assignment of R- and S- configuration of chiral centers. Equations explaining many of the reactions are shown at the discretion of the teacher. A set of notes for teachers is included which provides a brief explanation of the reactions and appropriate equations. The videodisc is arranged by functional groups into nineteen chapters, each with several segments. Chapter and segment titles are: Side A Chapter 1. Methane: Combustion of Methane Balloons; Combustion of Methane in a Bunsen Burner; Methane Molecular Models. Chapter 2.

The videodisc medium obviates concerns that normally accompany demonstrations: safety, availability and disposal of reagents, cost and time of constructing apparatus, and visibility of the presentations. See how this videodisc correlates with organic textbooks. See how this videodisc correlates with general chemistry textbooks. 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 handheld 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. Availability Available: Now
