Artham Resources | Class 12 Chemistry Half-Yearly Sample Paper with Solutions (Set 9)
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 advanced theoretical concepts, thermodynamic calculations, and stereochemical reaction mechanisms 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 solve complex numericals involving non-ideal solution deviations (Raoult’s law), calculate equilibrium constants from standard cell EMF, rationalize disproportionation reactions of manganese and chromium oxoanions, and deduce optical activity in halo-derivatives.
-
Case-Based & Data-Driven Analysis: Integrates data tables evaluating initial rates under varying catalyst concentrations, standard electrode potential series ($E^\circ$) comparison tables for $3d$ metals, and multi-step retro-synthetic organic pathways.
-
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 numerical-heavy physical sections, qualitative inorganic trend justifications, and structured organic reaction pathways without running out of time.
