Cochranes 分子模型

NB.17

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.
