19 chapter playbooks, grouped by the work they ask for

The mole in every form: mass, gas volume, solution concentration, percentage composition and the limiting reagent. Its arithmetic runs through every other physical chapter.

Work of expansion, heat and the first law, Hess's law, then entropy and Gibbs energy. Signs decide most answers: who does work on whom, and which way heat flows.

Rate laws and order, the integrated first-order law with its half-life, and the Arrhenius equation. Most questions are one formula with logarithms.

Kc and Kp, Le Chatelier, then ionic equilibrium: pH, buffers, salt hydrolysis and solubility product. The ionic half carries most of the calculations.

Photons, the Bohr model and the hydrogen spectrum, de Broglie and uncertainty, then quantum numbers and electron configuration. Half calculation, half counting electrons and orbitals.

Cell potentials and the Nernst equation, Gibbs energy from a cell, conductance and Kohlrausch's law, and Faraday's laws. Sign conventions and units decide the answer.

Concentration terms, Raoult's law, and the four colligative properties with the van 't Hoff factor for electrolytes.

Alkanes, addition to alkenes and alkynes, ozonolysis, aromaticity and substitution on benzene. Most questions ask which carbon the new group goes to.

Basicity, preparation, the tests that tell the classes apart, and diazonium salts with their replacement and coupling reactions.

Nucleophilic addition, the Grignard reagent, reductions, the tests, aldol and Cannizzaro, and acid strength. Short reaction schemes with a product to name.

The two substitution mechanisms and when each wins, the nucleophile and its product, elimination against substitution, and the haloarenes. Mechanism facts decide most answers.

Acidity of alcohols and phenols, dehydration with its carbocation shifts, the named reactions of phenol, and the cleavage of ethers by HI.

Naming, isomers, electron effects and reactive intermediates, then purification and the detection and estimation of elements. The heaviest chapter on the recent papers, and the base for every organic chapter.

Naming complexes, counting isomers, and crystal field theory with spin-only magnetic moments. Many of its numeric answers are counts from a list.

Electronic configurations, oxidation states and magnetic moments across the series, the lanthanoid contraction, and the chemistry of dichromate and permanganate.

VSEPR shapes, hybridisation, bond order from molecular orbital theory, dipole moments and hydrogen bonding. Mostly structure work on given molecules.

Carbohydrates, amino acids and proteins, vitamins, enzymes and nucleic acids. A recall chapter, with a few counts of peptides and stereocentres.

Periodic trends in size, ionisation enthalpy, electron gain enthalpy and electronegativity, with their known exceptions. Short questions, decided by the exceptions.

Groups thirteen to eighteen: trends, the inert pair effect, oxoacids, interhalogens and xenon compounds. Exact recall of structures and reactions.
