Sigma Aldrich Fine Chemicals Biosciences Cochranes molecular models
Supplier: Sigma Aldrich Fine Chemicals Biosciences Z6917471KT
With the Unit Large Demonstration Set you can show molecular shapes with rotating single bonds and non-rotating double and triple bonds structural isomers and optical isomers ring structures the chair-boat flip of cyclohexane and VSEPR theory.The set allows you to make models of hydrocarbons alcohols amines organic and inorganic acids and bases carbohydrates benzene chlorinated molecules inorganic molecules and more - that the whole class can seeThe system uses large (44 mm diameter) spheres in seven colors to represent different atoms plus a 25 mm diameter white sphere to represent a hydrogen atom. A versatile peg system allows you to use each large model atom in either tetrahedral (sp3) trigonal (sp2) linear (sp) trigonal bipyramidal (dsp3) and octahedral (d2sp3) geometries. These can be joined with either rigid alloy or flexible vinyl bond tubes.Bonds and atoms are to scale for accuracy at 8.5 cm per 100 pm.Set contentsModel atoms (total 70)Z691798 Carbon black (qty. 1
