Virtual 3D chemistry lab revolutionizes molecular learning through interactive simulation. Build molecules atom-by-atom: drag carbon, hydrogen, oxygen, nitrogen atoms; watch bonds form automatically following valence rules (carbon 4 bonds, oxygen 2, hydrogen 1); create water H2O (bent 104.5°), carbon dioxide CO2 (linear 180°), ammonia NH3 (pyramidal 107°), methane CH4 (tetrahedral 109.5°). Molecular geometry: VSEPR theory visualized (Valence Shell Electron Pair Repulsion predicts 3D shapes); see...
Master molecular geometry: VSEPR theory predict shapes (linear, bent, tetrahedral, pyramidal, trigonal planar), bond angles measure (104.5° water, 109.5° methane, 180° CO2), visualize 3D structures rotate space
Understand chemical bonding: ionic (electron transfer Na→Cl), covalent (electron sharing H:H), polar covalent (electronegativity δ+H-Clδ-), hydrogen bonds (weak DNA proteins), metallic (electron sea conductivity)
Build complex molecules: organic compounds (alcohols, aldehydes, ketones), biomolecules (amino acids, sugars), polymers (nylon, polyester), drugs (aspirin, caffeine), visualize functional groups reactivity
Simulate reactions: combustion (CH4+O2→CO2+H2O), acid-base (HCl+NaOH→NaCl+H2O), photosynthesis (CO2+H2O+light→glucose+O2), polymerization (monomers→chains), observe energy changes endothermic exothermic
