Rotate, drag, animate. Thirty interactive models and reference tools for the concepts students find hardest to picture — built for JEE & NEET Chemistry. Tap any card to open it full-screen.
Real s, p and d shapes — lobes, phases and nodal planes you can spin in 3D.
↗sp to sp³d² — VSEPR shapes and bond angles with real example molecules.
↗Side-on p-orbital overlap and the π cloud above and below the bond.
↗Six p-orbitals merging into the delocalised aromatic sextet.
↗σ, π and δ d-orbital overlap — the quadruple bond of Re₂Cl₈²⁻.
↗Bent bonds in cyclopropane and 3-centre bridges in diborane.
↗Nitrogen turning inside-out through a planar sp² transition state.
SC, BCC, FCC — atoms per cell, coordination number and packing efficiency.
↗HCP vs CCP packing, tetrahedral & octahedral voids, and NaCl / CsCl / ZnS / diamond lattices.
↗Interactive plots — reaction-order shapes, the Arrhenius line, and radial probability of orbitals.
↗Daniell cell & salt bridge, primary/secondary batteries and the H₂–O₂ fuel cell, with electrode reactions.
↗Speed distribution with a live temperature slider; pin curves to compare.
↗Expansion and compression with the live P–V area — a feel for work done.
The cube model — why d-orbitals split and why the order flips oct ↔ tet.
↗Ligand field-strength order (weak → strong), and how it sets colour, magnetism and high/low-spin.
↗14 VSEPR shapes — hypervalent halides, noble-gas fluorides, P₄ cluster.
↗Cation groups 0–VI & anion tests — reagent → observation, with the confirmatory tests.
Animated ring flip — watch axial and equatorial hydrogens swap places.
↗Rotate the dihedral of ethane & butane against a live torsional-energy curve.
↗Backside attack and Walden inversion, animated through the transition state.
↗Animated apparatus for sublimation, the four distillations, extraction and chromatography — with Rf and the JEE traps.
Every named reaction, grouped by what it does, with a one-line summary. Searchable.
↗Reagent → observation for every FG test — Baeyer, Tollen's, Lucas, iodoform and more.
↗What each reagent reduces, oxidises or hydrolyses — LiAlH₄, NaBH₄, KMnO₄, O₃ and more.
↗NCERT / JEE m.p. & b.p. data in °C and K, by class, with the intermolecular-force reasoning.
↗NCERT organic compounds — physical properties & real-world uses, plus polymer & carbohydrate tables.
↗Qualitative element detection (Lassaigne) and quantitative estimation (Liebig, Dumas, Kjeldahl, Carius) with formulas.
Physical-chemistry formulae, chapterwise, filtered by JEE / NEET / CET / Boards.
↗Rotate the table; map Z, mass, EN, IE or radius to colour & height.
↗Standard reduction potentials (E° / V), searchable — oxidising vs reducing strength, EMF, displacement.
