What Are Competency-Based Questions in Chemistry?

Competency-Based Questions assess a student’s ability to:

• Understand Core Concepts: Focus on conceptual clarity rather than memorization.

• Apply Knowledge in Practical Situations: Solve problems based on experiments, chemical reactions, or real-life applications.

• Think Analytically: Multi-step problems test logical reasoning and problem-solving skills.

Example: Predicting reaction products, calculating concentrations, or applying principles in unfamiliar contexts.

Benefits of Practicing CBSE Chemistry Competency-Based Questions

Practicing CBQs helps students:

• Deep Conceptual Clarity: Understand the why and how behind chemical reactions.

• Better Exam Performance: CBQs carry significant marks in board exams.

• Improved Problem-Solving Skills: Develop step-by-step reasoning.

• Competitive Exam Preparation: Builds foundation for IIT JEE, NEET, and other exams.

StudentBro.in offers chapter-wise CBQs to help students target weak areas and strengthen knowledge gradually.

Chapter-Wise Competency-Based Questions for Class 12 Chemistry

Our CBQs are organized by chapters for systematic preparation:

• Solid State: Crystal structures, packing efficiency, types of solids.

• Solutions: Molarity, molality, Raoult’s law, colligative properties.

• Electrochemistry: Conductance, electrochemical cells, Nernst equation.

• Chemical Kinetics: Reaction rates, order, molecularity problems.

• Surface Chemistry: Adsorption, colloids, catalysis.

• General Principles and Processes of Isolation of Elements: Metallurgy, extraction, refining techniques.

• p-Block Elements: Properties and reactions of groups 13 and 14.

• d-Block and f-Block Elements: Transition metals, complex formation, coordination chemistry.

• Organic Chemistry Sections: Alcohols, phenols, carbonyl compounds, amines, polymers.

• Biomolecules & Environmental Chemistry: Biomolecules, chemical processes in life, green chemistry.

This chapter-wise approach allows students to master individual topics and link concepts across chapters.

Tips for Solving CBSE Chemistry Competency-Based Questions

To excel in CBQs:

1. Carefully Read the Question: Identify key data and concepts.

2. Apply Fundamental Principles: Use chemical laws rather than rote solutions.

3. Draw Structures and Diagrams: Visual aids simplify complex reactions.

4. Solve Step by Step: Break multi-step problems into manageable steps.

5. Practice Regularly: Frequent practice improves speed and accuracy.
