Chemistry Labs
Interactive chemistry, built for NEET. Rotate it, test yourself, remember it.
Chemical Bonding & Molecular Structure
2 labsMethane
Explore the perfect 109.5° tetrahedral geometry of methane. Drag to rotate and see why sp³ hybridization gives this shape — the foundation of all alkane chemistry.
Hybridisation
Don't memorise shapes — build them. In the Play zone, electron-domain sticks repel each other and settle farthest apart, so you feel why the geometry is what it is. Then see every hybridisation — sp, sp², sp³, sp³d, sp³d² and sp³d³ hybrid orbitals — with their famous molecules and exact bond angles.
Atomic Structure
2 labsAtomic Orbitals
Visualize s, p, and d orbital shapes in 3D. Toggle between orbitals and understand why electron density takes these specific forms — the building blocks of every chemical bond.
Orbital Nodes
See the three kinds of orbital node in 3D — radial spheres, angular planes, and the conical nodes of d_z². Toggle each node type, slice the cloud open, and match them to the radial distribution curve.
Some Basic Concepts of Chemistry
1 labOrganic Chemistry — Some Basic Principles
1 labHaloalkanes & Haloarenes
1 labStates of Matter
1 labStoichiometry & Mole Concept
2 labsGram Equivalent
Match the equivalents of Na₂CO₃ (n=2) and HCl (n=1) on a 3D balance, then hit 'Mix them!' and watch both sides react to nothing — even though one pan weighs 53g and the other just 36.5g. Equal equivalents react, unequal mass.
N-Factor Explorer
Pour H⁺ ions onto the right pan of a 3D balance scale and see how many it takes to match one molecule's reacting power. Discover that n-factor = number of H⁺ a molecule gives or takes.
Structure of Atom
1 labClassification of Elements & Periodicity
2 labsIonisation Enthalpy
Strip electrons one by one off an isolated gaseous atom and feel the grip get stronger. Watch the energy jump when the noble-gas core breaks — that jump tells you the group.
Electron Gain Enthalpy
Offer an electron to a gaseous atom and watch the energy meter. Almost every atom is hungry — it gulps the electron and releases energy. Only Be, Mg, N and the noble gases refuse. And nobody wants the second electron.
