Karnataka 2nd PUC Chemistry Syllabus 2026-27: Chapters-wise Syllabus & Topics

Karnataka 2nd PUC Chemistry Syllabus 2026-27 is an important study resource for Class 12 Science students. It gives the list of units and topics prescribed for the Chemistry examination and should be used along with the latest blueprint and model question paper.

The current 2026-27 Karnataka PUC resources list Chemistry separately and show the active course structure around 10 units, beginning with Solutions and ending with Biomolecules. KSEAB has also released the Karnataka 2nd PUC Chemistry Blueprint 2026-27 and model paper for the 2027 examination.

One important point for students: older Karnataka Chemistry syllabus pages can still show chapters such as Solid State, Surface Chemistry, p-Block Elements, Polymers and Chemistry in Everyday Life. Those chapters belong to the broader older syllabus structure and should not automatically be treated as part of the current 2026-27 examination syllabus. The current board-resource listings show the reduced set of active units.

Karnataka 2nd PUC Chemistry Syllabus 2026-27: Chapter-Wise Topics

Unit 1: Solutions

The Solutions unit focuses on concentration, solubility and properties of liquid solutions.

Important topics include:

• Types of solutions

• Expressing concentration of solutions

• Solubility

• Vapour pressure of liquid solutions

• Ideal and non-ideal solutions

• Colligative properties

• Determination of molar mass

• Abnormal molar masses

Students should practise numerical problems along with the theory in this unit.

Unit 2: Electrochemistry

Electrochemistry deals with electrochemical cells and the relationship between chemical reactions and electrical energy.

Topics include:

• Electrochemical cells

• Galvanic cells

• Nernst equation

• Conductance of electrolytic solutions

• Electrolytic cells and electrolysis

• Batteries

• Fuel cells

• Corrosion

The Nernst equation and numerical applications require regular practice.

Unit 3: Chemical Kinetics

This unit explains the speed of chemical reactions and the factors that affect it.

The major topics are:

• Rate of a chemical reaction

• Factors influencing the rate of a reaction

• Integrated rate equations

• Temperature dependence of reaction rate

• Collision theory of chemical reactions

Students should understand the equations rather than memorising them without knowing their application.

Unit 4: The d- and f-Block Elements

This chapter covers the position, properties and applications of transition and inner-transition elements.

Topics include:

• Position in the periodic table

• Electronic configuration of d-block elements

• General properties of transition elements

• Important compounds of transition elements

• Lanthanoids

• Actinoids

• Applications of d- and f-block elements

The current blueprint allocates significant question coverage to this unit, making textbook-based revision important.

Unit 5: Coordination Compounds

Coordination chemistry forms an important part of the inorganic section.

Topics include:

• Werner's theory of coordination compounds

• Important terms related to coordination compounds

• Nomenclature

• Isomerism

• Bonding in coordination compounds

• Bonding in metal carbonyls

• Importance and applications of coordination compounds

Students should practise nomenclature and bonding questions repeatedly.

Unit 6: Haloalkanes and Haloarenes

This unit introduces students to compounds containing halogens and their reactions.

The syllabus covers:

• Classification

• Nomenclature

• Nature of the C–X bond

• Preparation of haloalkanes

• Preparation of haloarenes

• Physical properties

• Chemical reactions

Reaction-based questions are easier to handle when students understand the reaction mechanism instead of memorising individual reactions.

Unit 7: Alcohols, Phenols and Ethers

This chapter deals with the structure, properties and reactions of alcohols, phenols and ethers.

Topics include:

• Classification

• Nomenclature

• Structures of functional groups

• Alcohols and phenols

• Commercially important alcohols

• Ethers

Students should maintain a separate reaction chart for quick revision.

Unit 8: Aldehydes, Ketones and Carboxylic Acids

This is one of the larger organic chemistry units in the current syllabus.

Students need to study:

• Nomenclature and structure of the carbonyl group

• Preparation of aldehydes and ketones

• Physical properties

• Chemical reactions

• Uses of aldehydes and ketones

• Nomenclature and structure of the carboxyl group

• Preparation of carboxylic acids

• Physical properties

• Chemical reactions

• Uses of carboxylic acids

The chapter combines concepts, reactions and applications, so it needs repeated revision.

Unit 9: Amines

The Amines unit covers both amines and diazonium salts.

Topics include:

• Structure of amines

• Classification

• Nomenclature

• Preparation of amines

• Physical properties

• Chemical reactions

• Preparation of diazonium salts

• Physical properties of diazonium salts

• Chemical reactions

• Importance of diazonium salts in synthesis of aromatic compounds

Reaction conversion questions should be practised regularly.

Unit 10: Biomolecules

Biomolecules is the final unit in the current Karnataka 2nd PUC Chemistry syllabus.

It includes:

• Carbohydrates

• Proteins

• Enzymes

• Vitamins

• Nucleic acids

• Hormones

This unit contains several theory-oriented topics and can be revised effectively using short notes and tables.

Karnataka 2nd PUC Chemistry Syllabus 2026-27: Deleted Chapters

Students searching for Karnataka 2nd PUC Chemistry Deleted Chapters 2026-27 should be careful because several older websites still display the earlier 16-unit syllabus.

According to the current examination-pattern information, the following chapters from the older structure were removed:

These chapters were identified as deleted from the 2025-26 syllabus structure, and current 2026-27 resources continue to show the reduced 10-unit course.

Students should always match their preparation with the latest KSEAB document rather than an older textbook chapter list.

Karnataka 2nd PUC Chemistry Exam Pattern 2027

The Karnataka 2nd PUC Chemistry Exam Pattern 2027 has a total of 100 marks, divided into 70 marks for theory and 30 marks for practical assessment. The theory examination is conducted for three hours.

The current model-paper structure has different sections carrying different mark values.

The detailed blueprint should be followed for the exact number of questions, internal choices and unit-wise distribution.

Karnataka 2nd PUC Chemistry Marks Distribution

The subject carries 100 marks in total.

The 70-mark theory paper is conducted for three hours.

How to Download Karnataka 2nd PUC Chemistry Syllabus 2026-27 PDF?

Students can download the latest syllabus by following these steps:

1. Visit kseab.karnataka.gov.in.

2. Open the PUC examination or academic resources section.

3. Select 2nd PUC.

4. Find the Chemistry syllabus for the 2026-27 session.

5. Open the PDF and download it for future reference.

Students should also download the latest Karnataka 2nd PUC Chemistry Blueprint 2026-27 and model paper because the three resources serve different purposes. KSEAB's current 2026-27 subject-wise blueprint listing includes Chemistry as a separate downloadable resource.

Karnataka 2nd PUC Chemistry Important Chapters

Rather than depending on an unofficial list of “most important” chapters, students should use the latest blueprint to decide where to spend additional time.

For the current syllabus, students should pay close attention to:

Solutions and Electrochemistry: numerical problems and equations need practice.

Chemical Kinetics: rate equations and their applications require clarity.

d- and f-Block Elements: properties, configurations and important compounds need repeated revision.

Coordination Compounds: nomenclature, isomerism and bonding are important areas.

Organic Chemistry: Haloalkanes and Haloarenes, Alcohols/Phenols/Ethers, Aldehydes/Ketones/Carboxylic Acids and Amines require reaction practice.

The blueprint should remain the final reference for marks and question distribution.
