AP EAMCET 2026 Chemistry Detailed Syllabus

For the AP EAPCET 2026 (formerly AP EAMCET), the Chemistry syllabus is divided into three main branches: Physical, Inorganic, and Organic. Chemistry is widely considered the highest-scoring section because it is less time-consuming than Mathematics and more direct than Physics.

1. Physical Chemistry (Numerical & Conceptual)

This section focuses on the laws, theories, and mathematical aspects of chemistry. It typically accounts for 30-35% of the questions.

• Atomic Structure: Bohr’s model, Quantum numbers, Electronic configurations, and Dual nature of matter.
• Stoichiometry: Mole concept, Oxidation numbers, and Balancing redox reactions.
• States of Matter: Gas laws, Ideal gas equation, Graham's law, and Dalton’s law.
• Thermodynamics: System/Surroundings, Enthalpy ($H$), Entropy ($S$), and Gibbs Free Energy ($G$).
• Chemical Equilibrium & Acids-Bases: Le Chatelier’s principle, $K_p$ and $K_c$, pH scale, Buffer solutions, and Solubility product (K_{sp}).
• Solid State: Crystal lattices, Unit cells (BCC, FCC, SC), and Point defects.
• Solutions: Molarity/Molality, Raoult's Law, and Colligative properties (Osmotic pressure, Elevation in boiling point).
• Electrochemistry: Galvanic cells, Nernst equation, Kohlrausch's law, and Electrolysis.
• Chemical Kinetics: Rate laws, Order and Molecularity, First-order reactions, and Activation energy.
• Surface Chemistry: Adsorption (Physisorption/Chemisorption), Catalysis, and Colloids.

2. Inorganic Chemistry (Descriptive & Memory-Based)

This section is all about periodic trends and the behavior of elements. It accounts for 25-30% of the marks.

• Classification of Elements: Periodic trends (Atomic radii, Ionization Enthalpy, Electronegativity).
• Chemical Bonding: VSEPR Theory (shapes of molecules), Hybridization ($sp, sp^2, sp^3, sp^3d, sp^3d^2$), and Molecular Orbital Theory.
• s-Block Elements: Alkali and Alkaline Earth metals (Groups 1 & 2).
• p-Block Elements (Groups 13 & 14): Boron and Carbon families.
• Environmental Chemistry: Air, Water, and Soil pollution.
• p-Block Elements (Groups 15 to 18): Nitrogen, Oxygen, Halogen, and Noble gas families. (Highest weightage in Inorganic).
• d & f-Block Elements: Properties of transition elements, Lanthanides, and Actinides.
• Coordination Compounds: Werner’s theory, IUPAC nomenclature, and Valence Bond Theory (VBT).
• General Principles of Metallurgy: Extraction processes and refining of metals.

3. Organic Chemistry (Mechanisms & Reactions)

This is the largest section, accounting for 35-40% of the questions. Success here depends on understanding reaction mechanisms and named reactions.

• General Organic Chemistry (GOC): Inductive effect, Resonance, Isomerism, and IUPAC nomenclature.
• Hydrocarbons: Alkanes, Alkenes, Alkynes, and Aromatic hydrocarbons (Benzene).
• Haloalkanes & Haloarenes: $S_N1$ and $S_N2$ mechanisms.
• Organic Compounds with Oxygen:
  • Alcohols, Phenols, and Ethers: Preparation, Reactions, and Properties.
  • Aldehydes and Ketones: Structure, Preparation, and Reactions (including Cannizzaro reaction).
  • Carboxylic Acids: Structure, Preparation, and Reactions (including acid anhydrides).
• Organic Compounds with Nitrogen: Amines and Diazonium salts.
• Polymers: Classification and types (Nylon, Terylene, Buna-S).
• Biomolecules: Carbohydrates (Glucose/Fructose), Proteins, and Nucleic acids.
• Chemistry in Everyday Life: Drugs, Food additives, and Cleansing agents.
