Organic Vs Inorganic: Which Section Dominated CUET 2026 Chemistry Paper?

CUET UG 2026 Chemistry Paper Analysis: May 11 Overview

The overall difficulty was moderate. CUET chemistry question papers 2026 were a mix of direct NCERT-based MCQs and concept-application questions. Two Reading Comprehension (RC) passages appeared - one on d and f-Block Elements and one on an Organic Chemistry chain reaction. Named reaction matching and definition-based questions were prominent.

Here is how the paper was distributed:

Organic Chemistry in CUET UG 2026: Key Topics and Named Reactions

Organic Chemistry clearly had the highest weightage in the May 11 paper. The focus was entirely on named reactions, reagents, products, and limitations - not vague conceptual questions. If you know your named reactions well, Organic Chemistry is very scoring.

Named Reactions Are the Highest Priority

The paper tested not just whether you know a reaction exists, but whether you know its reagents, conditions, products, and limitations precisely. Just knowing the name is not enough.

Reactions you must know completely:

• Carbylamine Reaction - Primary amine + CHCl₃ + KOH → isocyanide. Only primary amines give this reaction. Used as a test for primary amines.

• Kolbe's Reaction - Sodium phenoxide + COâ‚‚ (high pressure, 400K) → salicylic acid

• Reimer-Tiemann Reaction - Phenol + CHCl₃ + NaOH → ortho-hydroxybenzaldehyde

• Hoffmann Bromamide Reaction - Amide + Brâ‚‚ + KOH → primary amine with one less carbon (chain shortening reaction)

• Sandmeyer Reaction - Diazonium salt + CuCl/CuBr/CuCN → ArCl/ArBr/ArCN

• Balz-Schiemann Reaction - For introducing fluorine: Diazonium salt + HBFâ‚„ → fluorobenzene

• Gabriel Phthalimide Reaction - Used to prepare primary aliphatic amines only

Know the Limitations - They Are Directly Asked

The May 11 paper asked which compound cannot be prepared by Gabriel Phthalimide reaction. The answer was aniline - because Gabriel Phthalimide can only prepare primary aliphatic amines, not aromatic ones.

Similarly, the Sandmeyer reaction question tested whether students know that fluorine cannot be introduced by Sandmeyer - Balz-Schiemann is needed for that.

These are classic NCERT limitation points. Examiners love asking what a reaction cannot do, not just what it can.

Aniline Reactions Are a Must-Revise

An entire RC passage was built around a chain reaction starting with aniline. Five consecutive reactions were given, and the product of each step was asked. If you know all reactions of aniline, this passage is very scoring.

All reactions of aniline you must know:

• Aniline + CHCl₃ + KOH → Phenyl isocyanide (Carbylamine)

• Aniline + Brâ‚‚/water → 2,4,6-tribromoaniline

• Aniline + NaNOâ‚‚ + HCl (0–5°C) → Benzene diazonium chloride (Diazotisation)

• Diazonium salt + CuCl → Chlorobenzene (Sandmeyer)

• Aniline + acetic anhydride → Acetanilide (Acylation)

Watch Out for Similar-Looking Answer Options

Students reported that Organic Chemistry was slightly tricky because answer options looked similar to each other. This means you cannot afford to be vague - you need to know exact products and exact conditions, not approximate ones.

Bottom line for Organic Chemistry: If you have limited time left, spend at least one full day exclusively on the Amines, Haloalkanes, and Haloarenes chapters. Go through every named reaction in NCERT one by one - reagents, conditions, products, and limitations.

Inorganic Chemistry in CUET UG 2026: High-Scoring Topics to Revise

Inorganic Chemistry was more definition and concept-based on May 11, making it more predictable and more scoring than Organic if you revise the right things.

Coordination Chemistry - Theory Definitions Were Directly Asked

A match-the-following question asked students to match CBT, VBT, Werner's Theory, and Crystal Field Theory with their definitions. This means you need to know each theory as a clear, distinguishable one-liner - not just that they exist.

Know these distinctions:

• Werner's Theory - Central metal has primary valency (ionisable, forms salts) and secondary valency (coordination number, non-ionisable). Foundation of coordination chemistry.

• VBT (Valence Bond Theory) - Explains geometry and magnetic nature of complexes through hybridisation of the central metal atom.

• CFT (Crystal Field Theory) - Based on electrostatic interaction between metal and ligands. Explains colour, magnetic properties, and splitting of d-orbitals (crystal field splitting, Δ).

The key distinction to remember: VBT explains geometry; CFT explains colour and splitting.

d and f-Block Elements - Came as an RC Passage

Rather than direct questions, d and f-Block appeared as a Reading Comprehension passage followed by questions. This is actually good news - you get to read context before answering. But you still need to know the core concepts.

Questions that came from this RC:

• Which transition element is colourless → Zn²⁺ (d¹⁰ - no d-d transition possible)

• Which is a non-transition element → Zinc (d¹⁰ in both atomic and ionic state)

• Which does not show variable valency → Zinc and Scandium

The most important NCERT point here: Zinc is a d-block element but NOT a transition element. This distinction is asked repeatedly in competitive exams.

Vitamin B12 - One Question, Easy Mark

The paper asked which disease is caused by Vitamin B12 deficiency. Answer: Pernicious Anaemia.

Also remember: Vitamin B12 (Cyanocobalamin) is a coordination compound with Cobalt as the central metal ion. This connects Biomolecules with Coordination Chemistry - a popular crossover point for examiners.

Bottom line for Inorganic Chemistry: Coordination Compounds and d and f-Block are your two most important chapters. Revise theory definitions and NCERT exception cases carefully - the paper specifically targeted elements and situations that do not follow general trends.

Physical Chemistry in CUET UG 2026: Important Formulas and Numericals

Physical Chemistry had a smaller presence on May 11 but what appeared was numerical and formula-based.

• Molar Conductance - One numerical was asked. Formula: Λm = (κ × 1000) / M

• Gibbs Energy - Questions based on two reactions. Know the four ΔH and ΔS combinations and their spontaneity conclusions.

These CUET chemistry important chapters are quick to revise. A one-hour focused revision of Electrochemistry formulas and Gibbs Energy conditions is sufficient.

CUET Chemistry 2026 Preparation Strategy: Chapter-wise Priority List

Based entirely on what May 11 paper showed:

Last-Minute Tips for CUET Chemistry 2026

• Read NCERT line by line for Organic - several questions in the May 11 paper were directly from NCERT examples and exercises

• For named reactions, make a one-page cheat sheet - reaction name, reagent, product, limitation. Revise it the night before

• For Inorganic, focus on exceptions - elements that don't show variable valency, ions that are colourless, compounds that can't be made by a particular reaction

• For Physical Chemistry, practice at least 5 numericals each on Molar Conductance and Gibbs Energy - the formulas are simple but unit conversions trip students up under exam pressure

• Attempt PYQs from 2022–2025 - the May 11 paper followed a similar pattern to previous years

Conclusion

The May 11 Chemistry paper rewarded students who had done thorough NCERT revision and focused on named reactions. Organic Chemistry was the highest weightage section but was slightly tricky - exact knowledge of products and limitations mattered. Inorganic Chemistry was more straightforward if you knew your theory definitions and NCERT exceptions. Physical Chemistry was limited but required numerical practice. If you are appearing on a later date, Amines and Coordination Compounds are your two highest-priority chapters. Everything else follows after those.
