Overview of CBSE Class 12 Chemistry Exam Structure

The CBSE Class 12 Chemistry exam is divided into two main parts: Theory and Practical . The theory exam holds a significant 70 marks, while the practical exam contributes 30 marks. Both sections are important for overall success, and students must work on both sections to perform well in the subject.

CBSE Class 12 Previous Year Question Papers

1. Theory Exam (70 Marks) The theory exam is divided into three main sections : Physical Chemistry, Inorganic Chemistry, and Organic Chemistry. There are a total of 10 units in the theory syllabus, which are divided into these three major branches of chemistry. Below is the detailed unit-wise weightage for CBSE Class 12 Chemistry theory exam. Physical Chemistry (23 Marks) Physical Chemistry deals with the principles and applications of physical properties of matter. The weightage for each unit in this section is as follows:
Unit Chapter Name Marks
Unit II Solutions 7
Unit III Electrochemistry 9
Unit IV Chemical Kinetics 7
Total Weightage 23
Key Focus Areas for Physical Chemistry:
  • In Solutions , students need to understand the properties of solutions, Raoult’s Law, and colligative properties.
  • Electrochemistry covers topics like electrode potential, Nernst equation, and applications of electrochemistry.
  • Chemical Kinetics involves the study of reaction rates, rate laws, and factors affecting the rate of reactions.
Inorganic Chemistry (14 Marks) Inorganic Chemistry involves the study of elements and their compounds, focusing on metals, non-metals, and coordination chemistry.
Unit Chapter Name Marks
Unit VIII d-block and f-block Elements 7
Unit IX Coordination Compounds 7
Total Weightage 14
Key Focus Areas for Inorganic Chemistry:
  • d-block and f-block elements deal with transition metals, lanthanides, and actinides, focusing on their properties and uses.
  • Coordination Compounds covers the study of ligands, coordination number, and applications in real-world scenarios.
Organic Chemistry (33 Marks) Organic Chemistry is an important section, as it covers many significant topics related to carbon compounds and their reactions.
Unit Chapter Name Marks
Unit X Haloalkanes and Haloarenes 6
Unit XI Alcohols, Phenols, and Ethers 6
Unit XII Aldehydes, Ketones, and Carboxylic Acids 8
Unit XIII Amines 6
Unit XIV Biomolecules 7
Total Weightage 33
Key Focus Areas for Organic Chemistry:
  • Haloalkanes and Haloarenes : Understanding the preparation, properties, and reactions of halogenated organic compounds.
  • Alcohols, Phenols, and Ethers : Focusing on the synthesis, properties, and reactions of these functional groups.
  • Aldehydes, Ketones, and Carboxylic Acids : Topics related to the preparation and reactions of carbonyl compounds.
  • Amines : The structure, nomenclature, and reactions of amines.
  • Biomolecules : Covering important biomolecules such as carbohydrates, proteins, and vitamins.

Class Record and Viva 4
Total Weightage 30
Key Focus Areas for Practical Exam:
  • Volumetric Analysis : Involves titrations and calculations based on acid-base or redox reactions.
  • Salt Analysis : Tests the ability to analyze the composition of salts and identify ions.
  • Content-Based Experiment : Students will need to perform a specific experiment and report results.
  • Project Work : Involves conducting a project related to Chemistry and presenting findings.
  • Class Record and Viva : Maintaining accurate records of experiments and demonstrating knowledge during the viva.

How to Prepare for CBSE Class 12 Chemistry 2024-25

  1. Understand the Weightage : Prioritize your study plan according to the weightage distribution. Focus more on Organic Chemistry, as it carries the highest marks, followed by Physical Chemistry and Inorganic Chemistry.
  2. Prepare for Practical Exams : Ensure you practice all practical experiments well in advance. Pay attention to maintaining accurate records and getting hands-on experience with all types of experiments.
  3. Use NCERT Textbooks : The NCERT textbooks are the primary resource for CBSE Chemistry preparation. Ensure you cover all chapters and understand the concepts thoroughly.
  4. Mock Tests and Previous Year Papers : Take mock tests and solve previous year papers to get an understanding of the exam format and improve time management skills.
  5. Focus on Conceptual Clarity : Chemistry involves many reactions and mechanisms, so ensure that you have a deep understanding of the concepts, not just rote memorization.
