A-Level Chemistry Lessons (Full Term, 2026)

We’ll revisit the core principles of bonding and structure, covering electron shells and orbitals, the shapes of orbitals, and electron configuration. We’ll then move on to the shapes of molecules and finish by exploring intermolecular forces and how they influence physical properties.

We’ll explore periodicity and the trends across the Periodic Table, focusing on ionisation energy and oxidation numbers using key graphs. We’ll also examine trends in melting and boiling points, before consolidating understanding of ionic, covalent, metallic, and dative bonding and how these bonding types determine material properties.

We’ll explore reactivity trends and key reactions with oxygen, water, and acids, linking these to trends in melting and boiling points. The focus will be on understanding solubility patterns of hydroxides, sulfates, and nitrates, and applying this knowledge to difficult exam questions.

We’ll explore Group 7 trends, including colours at room temperature and in different solvents, linking these to structure and bond enthalpy. The focus will be on displacement and disproportionation reactions, testing for halide ions, and applying these concepts to challenging exam-style questions.

We’ll cover qualitative analysis techniques for identifying carbonates, sulfates, halides, and ammonia. The focus will be on recognising key tests, observations, and equations, and applying them accurately to exam-style and unfamiliar questions.

We’ll explore enthalpy changes and how to calculate them using bond enthalpies and calorimetry (q=mcΔT)(q = mc\Delta T)(q=mcΔT). The focus will be on interpreting energy profile diagrams, applying Hess’s law, and handling energy loss to tackle challenging exam-style questions with confidence.

We’ll look into the factors affecting reaction rates, linking collision theory to the Boltzmann distribution. The focus will be on how homogeneous and heterogeneous catalysts work, applying Le Chatelier’s principle, and using these ideas to explain and predict outcomes in exam-style questions.

We’ll tackle the most challenging kinetics concepts, focusing on interpreting order graphs, identifying the rate-determining step, and applying the Arrhenius equation. The emphasis will be on mastering the hardest exam questions and avoiding common pitfalls.

We’ll focus on the most demanding equilibrium and kinetics questions applying Kc and Kp calculations and analysing cover qualitative analysis factors that affect the rate constant. The emphasis will be on handling multi-step high-difficulty.

We’ll cover acids and bases, including conjugate pairs, strong and weak acids and bases, and mixtures with excess reagents. The focus will be on interpreting pH curves, choosing appropriate indicators, and applying these concepts to the most challenging exam questions.

We’ll explore buffers, focusing on pH calculations, key equations, and their applications. The session will also cover haemoglobin, emphasising how to apply these concepts to the most challenging exam questions with confidence.

We’ll cover thermodynamics, including Born-Haber cycles, key “enthalpy of” definitions, lattice and hydration enthalpies, and calorimetry calculations (q=mcΔT,Δneut=−mcΔT)(q = mc\Delta T, \Delta_\text{neut} = -mc\Delta T)(q=mcΔT,Δneut​=−mcΔT). The focus will be on understanding factors affecting lattice enthalpy and applying these concepts to the hardest exam questions.
