12.1 Liquid Crystals Solid → liquid crystal → liquid Liquid crystals – exhibit properties of both liquids and crystalline solids Ordered arrangement Viscous liquid, non-solid Types of liquid crystal phases:

Examples of Molecules Long in comparison to width Flat benzene rings aid in stacking End polar groups promote allignment

Applications of Liquid Crystals Temperature monitors LCDs

12.2 Polymers “many parts” Large, high molecular weight molecular compounds Formed by joining monomers together through polymerization Examples: plastic, DNA, proteins, starch, rubber

Types of Polymerization Addition – monomers are added together forming bonds between them

Condensation Polymerization – monomers are joined with the elimination of a small molecule such as water Production of proteins: (See p. 1013)
