Set2, 10x molecular model kit 2

The molecular model kit 2 is an extension of the molecular model kit 1and can only be used with these. By combining the two boxes you can build numerous compounds in organic chemistry. With the benzene ring models aromatic hydrocarbons are vividly present. For organic remains the universal building blocks can be used. 2 teacher books "molecules" 10 molecular building blocks 2 with the following models: Sulfur atoms, yellow, hexavalent Sulfur atoms, yellow, bivalent Phosphorus atoms, purple, pentavalent Nitrogen atoms, blue, pentavalent Of carbon atoms, black, tetravalent Oxygen atoms, red, bivalent Universal blocks, gray, univalent Spiral fittings, gray Models of the benzene ring, can be dismantled, black Student Guide, "molecules"
