Artham Resources | Class 12 Chemistry Half-Yearly Sample Paper with Solutions (Set 14)
Strictly Aligned with CBSE Board Pattern & New NCERT Curriculum 2026–27
A full-length, board-calibrated 70-mark practice examination for Class 12 Chemistry designed to test electrochemical thermodynamics, transition element coordination chemistry, and complex organic reaction pathways under authentic 3-hour examination conditions.
Key Highlights & Academic Features
-
Authentic Examination Rigor: Calibrated to mirror official mid-term standards across Physical, Inorganic, and Organic Chemistry, balancing objective MCQs, Assertion-Reasoning items, structured short responses, case-based units, and long-form descriptive problems.
-
50% Competency-Focused Mandate: Packed with higher-order thinking skill (HOTS) questions requiring students to determine equilibrium constants ($K_c$) and standard cell potentials ($\Delta G^\circ$) from non-standard conditions, evaluate integrated rate expressions for zero and first-order systems, justify anomalous ionization enthalpies of transition metals, and trace stereochemical retention versus inversion during nucleophilic substitution.
-
Case-Based & Data-Driven Analysis: Integrates industrial battery discharge curves, concentration-dependent conductance profiles, catalytic cycle intermediates of $d$-block oxides, and road-map identification problems ($A \rightarrow B \rightarrow C$) involving haloarene derivatization and phenolic couplings.
-
Step-by-Step Marking Scheme: Delivers comprehensive, point-wise solutions detailing standard formula substitutions, explicit SI unit tracking, IUPAC naming conventions, essential reagents/temperature conditions, and structural diagrams.
-
Timed 3-Hour Simulation: Calibrated to train senior secondary science students in pacing across quantitative calculations, periodic trend explanations, and multi-tier organic deductions without running out of time.
