CUET Chemistry Preparation Strategy
Month 1-2: NCERT First Pass
Read all NCERT chapters once. Don’t skip in-text questions. Make formula sheets for Electrochemistry, Chemical Kinetics, and Solutions (colligative properties calculations).
Month 3-4: Topic-wise MCQ Practice
Practice 20-30 MCQs per chapter from previous CUET papers and similar competitive exam question banks. Focus on numerical-type questions in Electrochemistry, Solutions, and Kinetics.
Month 5-6: Full Tests and Revision
Take full Chemistry domain tests (45 min, 50 questions). Target 35+ correct out of 40 attempted for DU top colleges.
Practice MCQs — CUET Chemistry 2027
Q1. The unit cell of a metal has edge length a = 400 pm and body-centred cubic (BCC) structure. The atomic radius of the metal is:
(A) 100 pm (B) 141.4 pm (C) 173.2 pm (D) 200 pm
Answer: (C) For BCC: r = (√3/4)a = (1.732/4) × 400 = 173.2 pm
Q2. The rate constant of a first-order reaction is 0.0693 min⁻¹. The half-life of the reaction is:
(A) 0.0693 min (B) 10 min (C) 100 min (D) 14.4 min
Answer: (B) t₁/₂ = 0.693/k = 0.693/0.0693 = 10 min
Q3. According to VSEPR theory, the shape of BrF₅ molecule is:
(A) Trigonal bipyramidal (B) Square pyramidal (C) Octahedral (D) Pentagonal planar
Answer: (B) BrF₅ has 5 bond pairs + 1 lone pair = square pyramidal shape
Q4. Which of the following has the highest molar conductivity at infinite dilution?
(A) NaCl (B) MgCl₂ (C) AlCl₃ (D) HCl
Answer: (D) H⁺ ions have the highest ionic conductivity due to the Grotthuss mechanism
Q5. The IUPAC name of [Co(NH₃)₄Cl₂]Cl is:
(A) Tetraaminedichlorocobalt(III) chloride (B) Tetraaminedichloro cobalt(II) chloride (C) Tetraaminedichlorocobalt(III) chloride (D) Dichlorotetramminecobalt(III) chloride
Answer: (C) — Ligands in alphabetical order: amine before chloro; cobalt is +3
Frequently Asked Questions
Is NCERT enough for CUET Chemistry 2027?
Yes, NCERT is the primary and sufficient source for CUET Chemistry. The NTA designs CUET questions directly from NCERT Class 11 and 12 textbooks. Read each chapter thoroughly including in-text examples, exercises, and NCERT exemplar problems. Additional reference books are not required unless targeting very high scores.
How many questions come from Class 12 vs Class 11 in CUET Chemistry?
Based on CUET 2022-2025 analysis, approximately 60-65% of Chemistry questions come from Class 12 NCERT and 35-40% from Class 11 NCERT. Class 12 chapters like Electrochemistry, Coordination Compounds, Organic Chemistry (Ch 10-13), and Biomolecules receive the highest weightage.
Is CUET Chemistry difficult compared to JEE or NEET?
CUET Chemistry is significantly easier than JEE Chemistry and slightly easier than NEET Chemistry. CUET tests NCERT knowledge directly without the deep problem-solving complexity of JEE. Most questions are straightforward concept-recall or simple application. A student who has studied NCERT thoroughly can score 35-40/40 in CUET Chemistry.
Which DU colleges can I get with good CUET Chemistry scores?
For B.Sc. Chemistry (Hons.) at DU’s top colleges like Hindu College, Hansraj, Miranda House, or Ramjas, you need high scores across all your chosen CUET domain subjects plus the General Test. A Chemistry score of 180+ (out of 200) significantly improves your chances. DU uses a combination of CUET domain subject scores for science courses.
