Physical vs Organic vs Inorganic — How to Prioritise
Physical Chemistry (Chapters 1–5) — Score Builder
Physical Chemistry in CUET requires numerical ability combined with conceptual understanding. Solutions and Electrochemistry are the highest-yield chapters here. Key topics include: colligative properties (Raoult’s Law, osmotic pressure, elevation of boiling point, depression of freezing point), cell EMF, Nernst equation, rate laws, and order of reactions. These chapters together can account for nearly 20–25% of the paper if prepared well.
Recommended approach: Solve all NCERT in-text and end-of-chapter problems. Understand formulas rather than memorising them. Chemical Kinetics rate order questions and Electrochemistry EMF calculations are standard scoring opportunities.
Inorganic Chemistry (Chapters 6–9) — Factual and Theory-Based
Inorganic Chemistry is the most NCERT-text-dependent section. A large proportion of CUET Inorganic questions come directly from NCERT text sentences, tables, and boxed notes. Coordination Compounds is extremely important — naming, bonding theories (VBT and CFT basics), isomerism types, and crystal field theory must be studied from NCERT text carefully.
The d and f-Block Elements chapter tests properties of transition metals: variable oxidation states, colour of compounds, magnetic properties, and catalytic activity. The p-Block chapter covers properties of groups 15, 16, and 17 elements — oxides, hydrides, and interhalogen compounds are frequent CUET question areas.
Organic Chemistry (Chapters 10–16) — Reaction Mechanism Power
Organic Chemistry rewards students who understand reaction mechanisms, not just memorise them. Aldehydes, Ketones and Carboxylic Acids and Amines are the highest-scoring Organic chapters. Key reaction types that appear every year in CUET are listed in the next section.
Reaction Types That Appear Every Year in CUET Chemistry
- Aldol Condensation — Self-condensation of aldehydes/ketones with alpha-hydrogen in the presence of dilute alkali. Product identification questions are common.
- Cannizzaro Reaction — Disproportionation of aldehydes without alpha-hydrogen (e.g., formaldehyde, benzaldehyde). CUET asks: which compound undergoes Cannizzaro reaction?
- Reimer-Tiemann Reaction — Formylation of phenol using CHCl3 and NaOH. Product is salicylaldehyde.
- Hoffmann Bromamide Degradation — Amide to primary amine with one less carbon. Questions test product and reagent identification.
- Diazotisation and Coupling — Conversion of primary aromatic amine to diazonium salt and subsequent coupling with phenols/naphthalene to form azo dyes.
- Nucleophilic Substitution (SN1 and SN2) — Haloalkane reactions with NaOH, KCN, AgNO3. Questions test the type of mechanism and stereochemistry.
- Electrolytic Reactions (Kolbe’s Electrolysis) — Electrolysis of sodium acetate giving ethane.
The 80% NCERT Rule — Why It Works for CUET Chemistry
CUET Chemistry has a well-established pattern: approximately 80% of questions are framed directly from NCERT text, including in-text boxes, examples, and footnotes. The remaining 20% apply NCERT concepts to slightly unfamiliar situations. This means:
- Read each NCERT chapter at least twice — once for understanding, once for memorisation of key facts.
- Highlight all reaction equations in the NCERT book. These are the most frequently tested items.
- Read all NCERT examples and solutions — they often appear as direct CUET questions.
- Do not skip NCERT intext questions — these are built into the exam design.
Students who complete NCERT Chemistry honestly and then do 200+ MCQs of CUET pattern consistently score 150+ out of 200 in CUET Chemistry.

Frequently Asked Questions — CUET Chemistry 2027
Q1. Is Organic Chemistry difficult in CUET?
Organic Chemistry in CUET is manageable if you study from NCERT. CUET does not test complex multi-step synthesis problems like JEE Advanced. Instead, it tests NCERT-based reaction identification, product prediction, and IUPAC naming. Students who read NCERT Organic chapters carefully and practice reaction identification MCQs find this section scoring.
Q2. How many questions come from Inorganic Chemistry in CUET?
Based on past CUET patterns, Inorganic Chemistry (Chapters 6–9) typically contributes 12–16 questions. Coordination Compounds alone can account for 4–5 questions. The p-Block and d-f block chapters together contribute another 6–8 questions. Focusing on these chapters gives high returns for the time invested.
Q3. Should I use a reference book other than NCERT for CUET Chemistry?
For the primary preparation, NCERT alone is sufficient for 80% of CUET Chemistry. If you want supplemental MCQ practice, use CUET-specific question banks or previous year papers. Avoid JEE-level reference books like VK Jaiswal or MS Chauhan — they go far beyond CUET scope and will waste your preparation time.
Q4. What is the negative marking scheme in CUET Chemistry?
CUET follows a +5 for correct answer and -1 for wrong answer scheme. Since you attempt 40 out of 50 questions, avoid guessing randomly. If you can eliminate 2 options, attempting the question is statistically favourable. If you cannot eliminate any option, skip the question to avoid losing the -1 penalty.
