3D interactive mechanism simulations for H2 Chemistry. Rotate, pause, and explore at your own pace.

H2 Halogenoalkane Nucleophilic New
SN2 Mechanism
Backside attack of OH⁻ on 2-bromobutane. Watch the Walden inversion in real-time 3D with transition state pause.
H2 Halogenoalkane Nucleophilic New
SN1 Mechanism
Two-step ionisation via a carbocation intermediate — and why SN1 gives racemisation rather than inversion.
H2 Carbonyl Nucleophilic New
Nucleophilic Addition
Attack of CN⁻ on a carbonyl group — how the nucleophile targets the electrophilic C=O carbon.
H2 Alkene Electrophilic New
Electrophilic Addition
Addition of Br₂ to ethene — π bond attack, carbocation intermediate, and 1,2-dibromoethane product.
H2 Arene Electrophilic New
Electrophilic Substitution
Chlorination of benzene — how Cl⁺ attacks the aromatic ring and aromaticity is restored.
H2 Bonding New
VSEPR Theory
Explore all 13 molecular shapes across 2–6 electron pairs. Interactive 3D rotation with lone pair visualisation.
H2 Physical New
Gas Laws
Explore Boyle's and Gay-Lussac's Laws interactively. Watch particles collide as you adjust pressure, volume and temperature.
H2 Physical New
Maxwell-Boltzmann Distribution
Visualise how molecular speeds are distributed in a gas. Adjust temperature and see the curve shift — and where activation energy fits in.
