SIMPLE INORGANIC MOLECULAR KIT (LSE)
The basic Concepts about the Principles of molecular shape made easy. This kit offers a lot of 3 dimensional Models with a visual appreciation of Molecular Bonding. You can demonstrate how the shapes of Molecules are determined by the number of bonds plus the lone parts in the valence shell of the center atom. Showing lone pairs a unique specialty with these models. To show the molecule based on tetrahedron you can make methane, for triangle by pyramid, you can make phosphorus pentachloride; and for octahedron you can build Sulphur hexaflouride and soon. Some of the structures: CO2, CH4, PCI5, SF6, NH3, H2O, BCl3. Sulphur ring SH Oxides of Nitrogen, Phosphorous P4 molecule, h2 SO4, Simple Complexes & many more.
Contents: Oxygen, Nitrogen, Sulphur, Phosphorous, Chlorine, Hydrogen, Covalent & Multiple (total components about 140 nos. within a smart plastic case. A teachers guide/instruction manual with full details on how to make all these models).

ORGANIC MOLECULAR BUILDING KIT (LSE)
Innovatively designed for your convenience. This kit offers you the models for almost all the important structure covering each and very topic. The main speciality is the design of our atom with moulded prong to provide maneuverability for rotation. You can show the electron clouds. Separate tubes provided for covalent & multiple bonds. Hence, these models are way ahead of the ball & stick type. With this kit, you can build plenty of models. Saturated Hydrocarbons, unsaturated hydrocarbons, Functional groups: Alkanes, Alkenes, Alkynes, Alcohol’s, Aldehides & Ketons, Benzene & its Derivatives, etc. & many more.
Contents: Carbon, Oxygen, Nitrogen, Chlorine, Sulphur, Phosphorous, Hydrogen-atoms, Covalent bond Hydrogen bonds & multiple Bonds (Total components about 200 nos. within a smart plastic case. A teacher’s guide/instruction manual with full details on how to make is also provided). |
