Laboratory work #4: «Modeling Molecules of Organic Compounds»
Description: In this activity, students build models of simple aliphatic compounds (methane, ethane, propane, 1-chloropropane) using plasticine and toothpicks. Modeling helps visualize the structure of organic compounds, understand the principle of carbon tetravalency, and see the spatial arrangement of atoms in molecules.
