High School (11–12) Chemistry

Beyond the textbook: counting the isomers of any complex, filling the crystal field levels and calculating the stabilisation energy and the spin-only magnetic moment, and comparing the colour and stability of complexes. The problems that JEE, NEET and A-Level Chemistry ask most, with a full timed paper.

Beyond the textbook: concentration cells, cells with a precipitate or a complex, finding a solubility product or a pH from an emf, and electrolysis with competing ions. The problems that JEE, NEET and A-Level Chemistry ask most, with a full timed paper.

Beyond the textbook: counting the structural isomers of a formula and the stereoisomers of a molecule, and comparing the stability of intermediates and the acidity of compounds. The problems that JEE, NEET and A-Level Chemistry ask most, with a full timed paper.

The calculations that JEE, AP Chemistry and A-Level Chemistry set most: degree of dissociation from vapour density, simultaneous equilibria, pH of mixtures and very dilute solutions, polyprotic acids, and precipitation with Ksp, with a full timed paper.

The calculations that JEE, AP Chemistry and A-Level Chemistry ask most: work in reversible and irreversible expansions, Born-Haber and Hess cycles, bond enthalpies, and ΔG from ΔH and ΔS, with a full timed paper.

The hard questions of the chapter: dipole moments and molecular shape, tricky Lewis structures and formal charges, back bonding and bridges, and comparing bond lengths and energies, with a full paper.
