CBSE Class 12 Chemistry Exam 2026: Inorganic vs Organic Chemistry Weightage

The CBSE Class 12 Chemistry Exam 2026 is a crucial board examination for science students. Chemistry is not only important for board results but also forms the foundation for competitive exams such as JEE, NEET, and CUET. Understanding the Inorganic vs Organic Chemistry weightage is essential for strategic preparation.

The theory paper is conducted for 70 marks, while 30 marks are allotted for internal assessment. The question paper includes objective questions, short-answer questions, and long-answer questions. Since the marks are distributed across Physical, Inorganic, and Organic Chemistry, students must understand which section carries more weight in the CBSE Chemistry weightage 2026.

Inorganic vs Organic Chemistry Weightage in CBSE Class 12 Chemistry Exam 2026

When analyzing recent trends and previous board papers, the approximate weightage distribution is as follows:

• Organic Chemistry contributes around 40–45 percent of the theory paper.

•  Inorganic Chemistry contributes around 35–40 percent of the theory paper.

This means Organic Chemistry often has slightly higher weightage compared to Inorganic Chemistry in the CBSE Class 12 Chemistry Exam 2026.

However, both sections are equally important for scoring high marks.

Inorganic Chemistry Weightage in CBSE Chemistry 2026

Inorganic Chemistry typically contributes approximately 25 to 28 marks in the 70-mark theory paper. This section focuses mainly on conceptual clarity, periodic trends, and coordination chemistry.

Important Chapters in Inorganic Chemistry

• The p-Block Elements

• The d and f Block Elements

• Coordination Compounds

• Chemical Bonding and Periodicity (linked concepts)
  
  

Among these, Coordination Compounds is considered one of the most important chapters in the CBSE Class 12 Chemistry Exam 2026. Questions from this chapter often include nomenclature, isomerism, magnetic properties, and hybridization.

Nature of Questions in Inorganic Chemistry

Most questions in Inorganic Chemistry are concept-based and factual. Students are required to:

• Explain periodic trends

• Write balanced chemical equations

• Describe properties of elements

• Identify exceptions in trends

Since many questions are directly based on NCERT statements, careful reading of the textbook is essential.

Organic Chemistry Weightage in CBSE Chemistry 2026

Organic Chemistry generally carries slightly more marks, approximately 28 to 32 marks in the theory paper. Because of its broad syllabus and application-based nature, Organic Chemistry weightage is usually higher in the CBSE Class 12 Chemistry Exam 2026.

Important Chapters in Organic Chemistry

• Haloalkanes and Haloarenes

• Alcohols, Phenols and Ethers

• Aldehydes, Ketones and Carboxylic Acids

• Amines

• Biomolecules

• Polymers

• Chemistry in Everyday Life

These chapters include reaction mechanisms, named reactions, product prediction, and reasoning-based questions.

Nature of Questions in Organic Chemistry

The board exam commonly asks:

• Conversion-based questions

• Mechanism-based questions

• Product identification

• Reasoning questions

• Application-based case studies

Students who understand reaction mechanisms such as nucleophilic substitution, electrophilic substitution, addition, and elimination reactions can score well in this section.

Why Organic Chemistry Has Slightly Higher Weightage

There are three main reasons why Organic Chemistry weightage is often slightly higher:

• First, the syllabus is extensive and includes multiple functional groups and reaction types.

•  Second, it allows the board to frame analytical and application-based questions.

•  Third, chapters like Biomolecules and Polymers are relatively easy and scoring.

Therefore, students preparing for the CBSE Class 12 Chemistry Exam 2026 should allocate sufficient time to Organic Chemistry while not ignoring Inorganic topics.

How to Prepare for Inorganic Chemistry for CBSE Board Exam 2026

To score high in the Inorganic section, students should focus on:

• Understanding periodic trends such as atomic size, ionization energy, and electronegativity.

•  Learning reactions of p-block and d-block elements.

•  Practicing coordination compound nomenclature and isomerism.

•  Revising short notes regularly.

Consistent revision is the key to mastering the Inorganic Chemistry weightage in the board exam.

How to Prepare for Organic Chemistry for CBSE Board Exam 2026

For Organic Chemistry preparation 2026, students must:

• Understand reaction mechanisms instead of memorizing blindly.

•  Practice writing chemical equations with proper conditions.

•  Solve previous year board questions regularly.

•  Focus on conversion-based and reasoning questions.

Practicing daily helps improve accuracy and speed in writing reactions.

Common Mistakes Students Should Avoid

In Inorganic Chemistry, students often ignore small exceptions in periodic trends and forget reaction conditions. This leads to a loss of marks.

In Organic Chemistry, memorizing reactions without understanding mechanisms makes it difficult to solve application-based questions.

Avoiding these mistakes will improve performance in the CBSE Class 12 Chemistry Exam 2026.
