From Mole Concept to Biomolecules — Your Final CUET Chemistry Sweep

CUET chemistry 2026 - Last Minute Preparation (Interactive , tick off as you go) .

Covers full CUET Chemistry.

The scope which is

good to cover includes:

1. Physical Chemistry : It has a high calculation weightage - do not skip formulas.

1. Mole Concept - all inter-conversions, Avogadro's number applications. Practice at least 10 numerical problems back-to-back.
2. Atomic Structure -Bohr's model, quantum numbers, orbitals.Remember to learn the shapes of s, p, d orbitals and their orientations .
3. Chemical Equilibrium - Le Chatelier's principle, Kp & Kc.

The Relation Kp = Kc(RT)^Δn is a frequent direct question.

1. Thermodynamics -ΔG, ΔH, ΔS, spontaneity conditions ΔG = ΔH − TΔS and its sign-based interpretation is almost always tested.
2. Electrochemistry -EMF, Nernst equation, Faraday's laws,
3. Standard electrode potential table: Memorise the top 5 metals.
4. Chemical Kinetics - rate law, order vs molecularity, Arrhenius equation. Half-life formulas for first and second order reactions.
5. Solutions - Molarity, Molality, Colligative properties, Van't Hoff factor.

2. Inorganic Chemistry Mostly memory based - has the highest ROI per hour of study.

1. Periodic Table Trends - ionisation energy, electronegativity, atomic radius across periods & groups. Know the exceptions: N, O, F, anomalies in ionisation energy.
2. Chemical Bonding - VSEPR, hybridisation, bond angles of key molecules, Structures of H₂O, NH₃, SF₆, PCl₅, BeCl₂ must be on fingertips.
3. p-Block Elements - Group 15, 16, 17, 18 properties, oxoacids, hydrides. Allotropes of Sulphur and Phosphorus are frequently tested.
4. d & f Block - electronic configurations, oxidation states, colour of compounds. KMnO₄ and K₂Cr₂O₇ reactions in acidic and basic medium.
5. Coordination Compounds - IUPAC Naming, Isomerism, Crystal field theory basics. EAN rule and Werner's theory - quick revision only
6. s-Block Elements -Alkali & alkaline earth metals, their compounds and uses Diagonal relationship: Li-Mg, Be-Al — a favourite CUET MCQ area.

3. Organic Chemistry : Named reactions + mechanisms = maximum marks

1. General Organic Chemistry - Inductive, Mesomeric effects, Hyperconjugation, Stability of Carbocations and Carbanions - 3°>2°>1° is non-negotiable.
2. Hydrocarbons -Alkanes, Alkenes, Alkynes: reactions, additions, eliminations. Markovnikov's rule and its anti-Markovnikov exception with examples.
3. Aldehydes & Ketones, Nucleophilic addition, Cannizzaro, Aldol condensation,Distinguish between reactions of HCHO vs other aldehydes.
4. Amines - classification, basicity order, diazotisation, coupling reactions.Why aniline is less basic than aliphatic amines - must explain clearly.
5. Haloalkanes & Haloarenes - SN1 vs SN2, Elimination, Nucleophilic, Aromatic substitution.
6. Carboxylic Acids & Derivatives - Acidity, Esters, Amides, Acid chlorides.
7. Acidity comparison with Phenols and Alcohols is a frequent MCQ.
8. Benzene & Aromaticity - EAS reactions, directing effects of substituents o/p vs m-directors and their reasons - 5 minutes well spent.
9. Biomolecules & Polymers
10. Chemistry in Everyday Life:Pure memory based - revise in one sitting, score freely.
11. Carbohydrates: Monosaccharides, Disaccharides, Polysaccharides, Reducing sugars,Glucose structure (open and ring), Mutarotation, Anomers α and β.
12. Proteins - Amino acids, Peptide bonds, Primary/Secondary/Tertiary structure. Enzymes as Biological Catalysts and Denaturation.
13. Polymers - Addition vs Condensation, Natural vs Synthetic, Nylon, Bakelite, Teflon.
14. Drugs & Medicines - Analgesics, Antibiotics, Antacids, Antiseptics -with examples. Aspirin, Paracetamol, Penicillin, Chloramphenicol — names and uses
15. Nucleic Acids - DNA vs RNA, base pairing (A-T, G-C), double helix basics.
16. Surface Chemistry & States of Matter & Solid state : Concept-heavy but very predictable question patterns.
17. Solid State - Unit cells, Packing efficiency, Defects (Schottky, Frenkel) Number of atoms per unit cell: sc=1, bcc=2, fcc=4 — must memorise.
18. Gaseous State -Ideal gas equation, Real gases, Van der Waals equation.
19. Surface Chemistry: Adsorption, Colloids, types of sols, Tyndall effect, Coagulation. Lyophilic vs Lyophobic difference table takes 10 minutes and saves marks.
20. Catalysis - Homogeneous, Heterogeneous, Enzyme catalysis, Zeolites.

Last 72 Hours Strategy -What to do?:

1. Non-negotiable schedule for the final stretch:
2. Revise your personal "error log" - questions you got wrong in mock tests. This is more valuable than any new topic at this stage.
3. Attempt minimum of PYQ one full under timed conditions. Not to learn - just to calibrate your speed and identify last-minute gaps.
4. Write out all Named reactions on one sheet of paper - Aldol, Cannizzaro, Sandmeyer, etc.
5. Quick-fire formula revision - all Physical Chemistry formulas on one page comprising .
6. Thermodynamics Kinetics, Electrochemistry, Solutions: Read 3 times before sleeping.
7. Stop learning new content 24 hours before the exam - only revise what you know. New topics at this stage create confusion
8. Sleep 7–8 hours the night before. Remember that sleep consolidates memory.

Exam Day Tips :

Exam Hall Chemistry Strategy:

1. First Pass - 20 min: Answer everything you know instantly. Do not pause on hard questions. Mark and move.
2. Inorganic Memory-based Inorganic questions take 30 seconds each. Clear them before tackling numerical of Physical Chemistry.
3. Never Leave blanks in the Organic chemistry portion. Even if unsure, eliminate one or two options using reaction mechanism logic. Educated guesses in Organic pay off well .
4. In Numericals , the Unit mismatches cause errors. Always write units alongside every step of calculation in Physical Chemistry.
5. Set a personal 30-minute warning. If you are still on the first-pass, accelerate - do not panic.
6. Sometimes there is one unfamiliar question. Skip it, score the rest, return if time permits
