3B Scientific W19716 111 Piece Organic Molecular Model Teacher Set
This molecular model kit assists in the visual demonstration of key organic chemistry areas, including all functional groups. Groups included are; alkanes, alkenes, alkynes, alkyhalides, alcohols, ethers, aldehydes, ketones, carboxylic acids, nitriles, amines, esters, aromatic and heterocyclics. The kit contains a wide variety and large quantity of atom parts used to create many different possible organic and inorganic models. These models can be assembled and reassembled in a variety of configurations to represent each group. The set contains 24 black, 4-hole tetrahedron carbon atoms, and 14 black carbon atoms (6 trigonal bipyramidal, 2 linear, and 6 triagonal). The kit also contains 12 red oxygen atoms, 40 white hydrogen atoms, 4 blue tetrahedryl nitrogen atoms,  1 yellow tertrahedryl sulphur, 1 yellow octahedryl sulphur atom, 4 purple phosphorus atoms, 8 green halogen atoms, 2 one-hole grey metal atoms, and 1 grey metal atom. Also included are 55 medium length grey links, 25 flexible long grey links, and 60 short white links, with one link remover tool. Each kit comes in a plastic box for ease of storage.
