12th Class Chemistry Paper Scheme 2025 for All Punjab Boards (PDF Available)

Students of FSc Part 2 who are preparing for their board exams can now check the 2nd Year Chemistry Pairing Scheme 2025 for all Punjab Boards. This official scheme helps you understand the marks distribution, chapter pairing, and important short and long questions expected in the annual exam 2025.

This pairing scheme is valid for all Punjab Boards, including Lahore Board, Faisalabad Board, Multan Board, Sargodha Board, Gujranwala Board, DG Khan Board, Rawalpindi Board, Bahawalpur Board, and Sahiwal Board.

Why You Should Follow the Chemistry Pairing Scheme

Chemistry is a subject that requires both conceptual understanding and numerical practice. Many students face difficulty because they don’t know which chapters carry more weight in the final paper.
By following the 12th Class Chemistry Pairing Scheme 2025, you can:

• Identify important chapters for theory and numericals

• Focus on key topics rather than wasting time on less important ones

• Improve your chances of scoring above 80% marks

• Prepare smartly for MCQs, short questions, and long questions

2nd Year Chemistry Paper Pattern 2025

The 12th Class Chemistry paper is divided into three main parts:

1. Objective Part (MCQs)

2. Short Questions (Subjective Part I)

3. Long Questions (Subjective Part II)

Let’s go through each section according to the latest scheme.

MCQs Section

Each chapter carries 1–2 MCQs. A total of 17 MCQs will be asked in the objective part.

Short Questions

Each question carries 2 marks. You’ll attempt 8 out of 12 in each section.

Question 2 (Chapters 1–4)
Question 3 (Chapters 5–8)
Question 4 (Chapters 9–11)

Prepare definitions, chemical equations, and conceptual short questions from these chapters.

Long Questions (Theory + Numerical)

You’ll attempt any 3 questions out of 5. Each question has two parts (a & b) — each carrying 4 marks.

Important Topics to Prepare

Don’t skip these important topics if you want high marks:

• Raoult’s Law & Colligative Properties

• Faraday’s Laws of Electrolysis

• Activation Energy and Rate of Reaction

• Enthalpy Changes and Hess’s Law

• Le Chatelier’s Principle

• pH Calculations & Ionic Product of Water

• Periodic Properties of Elements

• Transition Metals and Complex Compounds

Practical List (For Viva and Lab Exam)

• Preparation of Standard Solution

• Determination of Heat of Neutralization

• Study of Reaction Rate

• Electrolysis of Copper Sulphate Solution

• Detection of Cations and Anions

Tips for Chemistry Exam 2025

• Revise numericals and equations thoroughly.

• Focus on past paper short questions — many are repeated.

• Memorize chemical reactions with their conditions.

• Understand concepts instead of rote learning for long questions.

Conclusion

The 2nd Year Chemistry Pairing Scheme 2025 gives you a clear roadmap for smart preparation. Follow this scheme to identify important chapters, practice key numericals, and focus on areas that carry the highest marks.
