Resumen:This kit enables users to build virtually all simple molecules encountered in organic chemistry.top. Features 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. Set Includes: 28 Hydrogen (white). 14 Carbon (black). 8 Oxygen (red). 4 Nitrogen (blue). 8 Chlorine (green). 2 Bromine (orange). 2 Iodine (purple). 40 Single Bond, Space-filling Models (white). 40 Single Bond, Open Models (short grey). 12 Double and Triple Bonds, Open Models (long grey).
