Students can use this ball-and-stick set to construct realistic scale models illustrating the molecular structures of thousands of organic compounds. The models will bring to life such concepts as stereoisomerism and conformational analysis, and will help students relate the physical and chemical properties of compounds to their molecular structures. *Includes space-filling models that simulate the true shape of saturated compounds. *Provides open models that form realistic single, double, and triple bonds - even strained rings. *Allows smooth rotation of the bonds to make conformational analysis easy. *Contains enough components to create several models at once. *The components are precision-tooled from quality plastics, are virtually indestructible, and come in a sturdy plastic case for easy storage. *Provides a useful Instruction Book - with photos, diagrams, and concise discussions of chemical principles.
