General description

Learn about molecular shape, stereochemistry, isomerism and bonding in organic and inorganic molecules and complex ions. This Orbit set is suitable for students, teachers and researchers doing chemistry at advanced school level, college or university. The contents enable the construction of many different molecules and allow comparison of different structures including saturated hydrocarbons, unsaturated hydrocarbons, cyclic hydrocarbons, functinal groups in organic chmeistry, benzene, polymerization, optical isomerism, simple inorganic milecules and complex ions. Includes instruction/activity booklet, Z129070.

An extensive model system offering 15 atomic bonding configurations in 12 colors of plastic atoms. The carbon atom is represented in nine configurations: linear, trigonal (in five angle variations), tetrahedral, octahedral, trigonal-bipyramidal. Models come in two sizes: Orbit and Minit. Spare atom centers and bonding tubes are available for all model kits.
