Large Set for Organic and Inorganic Chemistry

Large Set for Organic and Inorganic Chemistry – Educational Molecular Models

The set contains 212 elements made of colorful plastic (in the previous version: 192 elements) enabling the construction of a very wide range of chemical structures. The set includes models of elements such as carbon, hydrogen, nitrogen, oxygen, sulfur, phosphorus, halogens and metals - each element is represented by 1-5 types of models; for example, phosphorus is represented by three sphere models with 4, 5 and 3 openings and angles 109, 90 and 120 and 107, respectively. Bonds (including single covalent, double, triple, coordinate and ionic) are symbolized by 3 types of connectors. Additional elements are 3 types of pear-shaped leaves (total 18 pieces), which can represent lone pairs of electrons found in water and ammonia or characteristic bonds found in ethyne and benzene.

From the elements of the set you can build, among others: molecules (e.g., hydrogen, chlorine, oxygen, ozone, nitrogen, phosphorus, sulfur, carbon - various allotropes), hydrides (e.g., sodium, magnesium, silicon and hydrogen chloride, ammonia, methane, water, hydrogen sulfide), chlorides and fluorides, metal oxides, non-metal oxides, acids, metal ions, organic compounds (e.g., benzene, glycerol, ethane, ethyne, acetone, ethanol, etc.). Built structures are large, and more importantly - clear and transparent.
Atoms have a diameter from 17 mm to 23 mm.

The set enables constructing organic molecules (with different functional groups) and inorganic ones, including: C₂H₂ (ethyne), CH₃CH₂OH (ethanol), CH₃COOH (acetic acid), CH₃COOCH₃ (ethyl formate), CH₃CHO (acetone), CH₂OHCH₂OH (ethylene glycol), H₂NCH₂COOH (glycine), CH₃CHNH₂COOH (alanine), C₆H₁₂O₆ (glucose), H₂NCH₂CONHCHCH₃COOH (Gly-Ala: produced as a result of condensation of glycine and alanine, forming a peptide bond HNCO), C₆H₁₂ (cyclohexane), H₂SO₄ (sulfuric acid), HClO₄ (perchloric acid), H₃PO₄ (phosphoric acid), H₂CO₃ (carbonic acid), HCl (hydrochloric acid).
