IB Chemistry
IB Chemistry HL and SL — organic mechanism precision, calculation mastery, all option topics, IA support, and strong outcomes for Medicine and Pharmacy applicants.
What is IB Chemistry?
IB Chemistry is one of the most demanding IB sciences, combining Physical, Organic, and Inorganic Chemistry with significant mathematical content and a rigorous Internal Assessment requirement. Higher Level Chemistry extends considerably beyond SL with advanced energetics, kinetics, organic mechanisms, and spectroscopic identification — content that approaches first-year university Chemistry in its depth. IB Chemistry is an essential prerequisite for Medicine, Dentistry, Pharmacy, Biochemistry, and Chemical Engineering at top universities. In Dubai's competitive IB school environment, achieving a 6 or 7 in Chemistry HL is often the determining factor for medical school offers. At Improve ME, our IB Chemistry tutors combine deep subject expertise with precise mark scheme knowledge to deliver consistently strong outcomes at both HL and SL.
IB Chemistry Course Content
SL & HL coverage plus Internal Assessment (IA) support and exam strategy.
Core Topics (HL and SL)
- Stoichiometry — mole concept, empirical and molecular formulae, limiting reagents, percentage yield and purity, concentration calculations, titration
- Atomic Structure — nuclear atom, electron configuration, emission spectra, ionisation energy trends
- Periodicity — periodic trends in atomic radius, ionic radius, ionisation energy, electronegativity, melting points; reactivity of Period 3 elements and oxides
- Chemical Bonding and Structure — ionic, covalent, metallic bonding; VSEPR theory and molecular geometry; intermolecular forces; polarity; giant structures vs molecular structures
- Energetics — standard enthalpy changes, Hess's Law, bond enthalpy, Born-Haber cycles (HL), entropy, Gibbs free energy (HL)
- Chemical Kinetics — rate of reaction, Maxwell-Boltzmann distribution, Arrhenius equation, rate expressions and order of reaction (HL), reaction mechanisms (HL)
- Equilibrium — dynamic equilibrium, Le Chatelier's principle, equilibrium constant expressions (Kc and Kp), acid-base equilibria, pH calculations, buffer solutions, Kw and Ka (HL)
- Acids and Bases — Brønsted-Lowry theory, strong and weak acids and bases, pH calculations, salt hydrolysis, indicators, titration curves
Organic Chemistry and HL Extensions
- Organic Chemistry Core — nomenclature and isomerism (structural, geometric, optical), functional group reactions, alkanes and alkenes, halogenoalkanes (nucleophilic substitution), alcohols, carbonyl compounds, carboxylic acids and esters
- Organic Chemistry HL — reaction mechanisms (SN1 and SN2 in depth, electrophilic addition, electrophilic aromatic substitution, nucleophilic acyl substitution), benzene chemistry, amines, diazonium salts, amino acids and proteins, condensation polymerisation
- Spectroscopy and Identification — mass spectrometry, IR spectroscopy (identifying functional groups), 1H NMR spectroscopy (chemical shift, integration, splitting patterns), combined spectral analysis (HL)
- Measurement and Data Processing — significant figures, uncertainty propagation, graphical analysis, percentage error, experimental design and evaluation
Internal Assessment and Option Topics
- Chemistry IA — individual investigation worth 20%; assessed on Personal Engagement, Exploration, Analysis, Evaluation, and Communication
- IA research question design — writing a focused, investigable RQ with clear independent and dependent variables and controlled variables
- Data collection and processing — recording raw data, calculating averages, propagating uncertainties, presenting processed data in tables and graphs
- Evaluation — discussing sources of error and uncertainty, evaluating the validity of the method, suggesting realistic improvements
- Option topics — choose one: Materials (metals, polymers, nanotechnology, condensation polymers), Biochemistry (proteins, carbohydrates, lipids, enzymes, vitamins), Energy (fossil fuels, nuclear, solar, electrochemical), Medicinal Chemistry (drug action, antiviral and antibacterial agents, stereochemistry of drugs)
- Option topic preparation — each option covers approximately 20 hours of teaching content and appears in Paper 3 Section B
Assessment Structure
We support both Internal Assessment (IA) and final exams with a structured plan, feedback cycles, and timed practice. SL and HL requirements are clearly differentiated.
- SL: 45 mins, 20% — 30 MCQ; tests quick conceptual recall and eliminates common misconceptions; no data booklet on Paper 1.
- HL: 60 mins, 20% — 40 MCQ; same focus with greater breadth.
- SL: 75 mins, 40%; HL: 135 mins, 36% — short and extended response; includes calculations, mechanism drawing (Chemistry), and 8–10 mark extended response questions requiring full working and explanation.
- Data booklet provided for Papers 2 and 3; students must know how to use it efficiently.
- SL: Paper 3 — 60 mins, 20% (data analysis + option topic); HL: 75 mins, 24%.
- Section A: unfamiliar experimental data for analysis; processing raw data, graphs, gradients, evaluation of methodology.
- Chemistry IA: individual investigation worth 20%; assessed on Personal Engagement, Exploration, Analysis, Evaluation, and Communication.

Our IB Chemistry Teaching Approach
HL/SL Content Distinction
HL Chemistry adds significant additional depth in energetics, kinetics, equilibrium, and organic chemistry. We teach HL and SL content separately and ensure HL students are fully prepared for the additional theoretical and mathematical demands of Paper 2.
Calculation Mastery
IB Chemistry is heavily calculation-based — pH, Kc, Kp, Gibbs free energy, Arrhenius, and stoichiometric calculations all appear across Papers 1 and 2. We drill these systematically with attention to method, significant figures, and units — the details that cost marks even when the chemistry is correct.
Mechanism Precision
Organic reaction mechanisms are the most heavily examined area of IB Chemistry HL and one of the most common sources of mark loss. We teach every mechanism until students can draw them perfectly with correct curly arrow notation, charges, and intermediate structures under exam conditions.
IA Excellence
A high-scoring Chemistry IA requires a well-designed investigation, precise data collection, correct uncertainty propagation, and an evaluative conclusion that goes beyond simply identifying errors. We support students through every stage and review drafts against all five IB criteria.
