CUET 2026 Chemistry Paper Questions Asked in the Exam

CUET 2026 Chemistry Paper Questions Asked in the Exam have been provided for the candidates' reference and understanding, to get an idea of the concepts and high-weightage section for the exam. 

1. Physical Chemistry

Colligative Properties & Solutions

Core Concepts: Finding the lowest or highest boiling points, calculating osmotic pressure variations, and tracking the Van 't Hoff factor (i).

Sample Problem 1: Boiling Point Elevation

Identify the lowest boiling point at 1 atm among 0.1 M solutions of KCl, Urea, CaCl2, and AlCl3.

• Method: Elevation in boiling point follows the formula:

Delta T_b = i * K_b * m

• Explanation: Because the concentration (m) is identical for all solutions, a lower Van 't Hoff factor (i) results in a lower boiling point.

• KCl (i = 2)

• Urea (i = 1)

• CaCl2 (i = 3)

• AlCl3 (i = 4)

• Conclusion: Urea has the lowest i value (i = 1), making it the correct choice.

Sample Problem 2: Osmotic Pressure Ranking

Ranking different solution types based on their total osmotic pressure uses the expression:

pi = i * C * R * T

Sample Problem 3: Freezing Point Depression Calculation

Determine the freezing point of a 0.1 M NaCl solution given K_f = 1.86 K kg mol-1.

• Solution Path:

Delta T_f = i * K_f * m

Delta T_f = 2 * 1.86 * 0.1 = 0.372 degrees Celsius

Freezing Point (T_f) = 0 degrees Celsius - 0.372 degrees Celsius = -0.372 degrees Celsius

Raoult's Law & Liquid Mixtures

Total vapor pressure of an ideal binary solution is determined using:

P_total = (P_A * X_A) + (P_B * X_B)

Exam Variant Note: Pay close attention to deviations from ideal behavior. For example, Water + Acid mixtures exhibit a negative deviation due to strong intermolecular hydrogen bonding that keeps the molecules from evaporating easily.

Electrochemistry

Commercial Batteries

This topic is highly emphasised. Review the specific categories, operational mechanisms, and cell structures:

• Primary Cells: Non-rechargeable. Used in TV remotes and wristwatches. Examples include the standard Dry cell (Leclanche) and the Button cell.

• Secondary Cells: Rechargeable. Used in home inverters and power banks. Examples include the Lead-storage battery and the Nickel-Cadmium cell.

• Fuel Cells: High efficiency. Converts combustion energy directly to electrical energy. The Hydrogen-Oxygen Fuel Cell is widely used in aerospace programs like the Apollo space mission.

• High-Yield Fact: The Lead-storage battery uses a Lead (Pb) anode, a Lead dioxide (PbO2) cathode, and a 38 percent Sulfuric Acid (H2SO4) solution as its liquid electrolyte.

Faraday's Laws of Electrolysis

Calculates the charge transferred during redox changes.

• Example: The oxidation of 1 mole of H2O to O2 involves a 2-electron transfer process.

Charge = n * F = 2 * 96500 C = 1.93 * 10^5 C

Chemical Kinetics

• Activation Energy: Expect conceptual or graphical multiple-choice questions regarding energy barriers rather than long mathematical formulations.

• Rate Laws: Be prepared to write differential expressions tracking the rate of formation or appearance of products versus the rate of disappearance of reactants based on balancing coefficients. 

2. Inorganic Chemistry

d and f-Block Elements

• 3D Transition Series: Focus closely on horizontal periodic trends concerning atomic size contraction, common oxidation states, and ionic stability properties.

• Magnetic & Optical States: Be ready to determine whether a transition metal complex ion is colored or colorless.
  Rule: Ions with empty (d0) or full (d10) subshells do not undergo d-d transitions and appear colorless (such as Zn2+). Subshells containing unpaired electrons (d1 through d9) appear colored.

• Oxidising Compounds: Pay attention to chemical setups, structure changes, and pH-dependent redox reactions of Potassium Permanganate (KMnO4) and Potassium Dichromate (K2Cr2O7).

Coordination Compounds

Valence Bond Theory (VBT) & Crystal Field Theory (CFT)

These matching concepts are vital for decoding coordination geometry. You will be asked to predict:

• Hybridization types: Tracking inner orbital (d2sp3) versus outer orbital (sp3d2) configurations.

• Magnetic nature: Differentiating paramagnetic versus diamagnetic behaviors by counting unpaired electrons.

• Crystal Field Splitting Energy (CFSE): Estimating splitting values (Delta_o or Delta_t) by assessing strong-field versus weak-field ligands using the spectrochemical series.
