Polysaccharides are polymers of ; they play essential roles in energy storage, signalling, and as structural components in all living organisms. The only ones we will be concerned with here are those composed of , the most important of the six-carbon . Glucose serves as the primary fuel of most organisms.

Polybutadiene substitutes a hydrogen for the chlorine; it is the major component (usually admixed with other rubbers) of tires. Synthetic rubbers played a crucial role in World War II:

It is amusing that, contrary to the original speculations about natural rubber, the rubber tree clearly does not use isoprene as such in its synthesis of rubber, and chemists have been led to duplicate a natural product by a process entirely different from that used by nature. The chemical and technological importance of industrial rubber syntheses is immense.

Nylon, dacron and orlon are all synthetic fabrics.

Background information for alkenes, alkynes, and dienes are described in terms of definitions, properties, uses, structures, and classification. The rules for the IUPAC nomenclature of alkenes, alkynes, and dienes are discussed. Alkenes are additionally named using cis and trans or E and Z. Alkenes are synthesized by the dehalogenation of alkyl halides and the dehydration of alcohols. Alkynes are synthesized by the dehydrohalogenation of vicinal and geminal dihalides. Alkyl halides are formed by the reaction of alkenes with hydrogen halides. Alkenes are halogenated to give dihaloalkanes. Alkenes are hydrated to give alcohols. Reduction of alkenes give alkanes. Alkynes react with hydrogen halides to give dihaloalkanes or with halogens to give tetrahaloalkanes. Hydrogenation of alkynes give alkanes. Alkenes are polymerized. Alkenes are oxidized to diols with potassium permanganate or to aldehydes and / or ketones with ozone. Alkynes are oxidized to diketones with potassium permanganate or to carboxylic acids with ozone.

The most important synthetic rubber is, however, a copolymer of butadiene and styrene (Fig. 3-10). Styrene is phenylethylene, where phenyl is the radical derived from benzene (C6H6) by removal of one hydrogen. (We will see in "Aromatic Compounds" more of benzene and learn the reason for the hexagon with a circle in it.) A large percentage of the tires in use today are made of this rubber (originally called GR-S for Government Rubber-Styrene type, because its development was sponsored by the U.S. Government in a crash program to replace natural rubber during World War II).

Synthesis of Alkenes
Alkyl halides are dehydrohalogenated with base to form alkenes. Alcohols are dehydrated with heat and acid to form alkenes. The product with the most number of carbons attached to the carbon-carbon double bond is formed in the higher yield.

The first plastic (Celluloid) and the first artificial fiber(Rayon) were produced from .The first truly synthetic plastic was bakelite, developed by LeoBaekland between 1905 and 1914. The synthesis of bakelite startswith the reaction between formaldehyde (H2CO) andphenol (C6H5OH) to form a mixture of ortho-and para-substituted phenols. At temperatures above100C, these phenols condense to form a polymer in which thearomatic rings are bridged by either -CH2OCH2-or -CH2- linkages. The cross-linking in this polymeris so extensive that it is a thermoset plastic. Once it isformed, any attempt to change the shape of this plastic is doomedto failure.
