By checking the official syllabus before starting the course, students can plan their studies in the right order, focus on high-weightage units and complete timely revision before tests. Some of the important topics covered in the Class 11 Chemistry syllabus are:

• States of Matter and Some Basic Concepts of Chemistry
• Structure of Atom and Chemical Bonding
• Classification of Elements and Periodicity
• Chemical Thermodynamics and Equilibrium
• Redox Reactions and Environmental Chemistry (as extension)
• Organic Chemistry – Basic Principles and Techniques
• Hydrocarbons and related reaction mechanisms
• Practical Chemistry and Laboratory Skills

Overview of CBSE Class 11 Chemistry Syllabus 2025-26

Class 11 Chemistry introduces learners to the language of chemistry, atomic structure, chemical bonding, states of matter, thermodynamics, equilibrium, redox reactions, hydrogen, s-block and p-block elements, organic chemistry fundamentals, hydrocarbons and environmental concepts. The subject combines theory with laboratory work so that students understand how chemical principles are applied in real life, industrial processes and laboratory experiments.

Studying the syllabus in sequence, solving NCERT questions, practicing numerical problems and revising definitions, laws and derivations helps students gain confidence in science and maths based chapters. A careful reading of the marking scheme also guides students in selecting which units need extra practice for board exam preparation.

CBSE Class 11 Chemistry Syllabus – Unit-wise Marks Distribution

How To use this table: The table below gives unit names, number of periods and marks for Class 11 Chemistry. Students should note which units carry higher weightage and ensure that they balance numerical practice, theory revision and lab-related questions for those topics.

From the table, students can see that Organic Chemistry: Some Basic Principles and Techniques (11 marks) and Hydrocarbons (10 marks) together form a large portion of the paper. At the same time, conceptual physical chemistry units like Structure of Atom and Chemical Thermodynamics also carry 9 marks each. A balanced study plan should therefore include regular problem-solving for numerical topics and repeated revision for conceptual and mechanism-based questions in organic chemistry.

Chapters like Some Basic Concepts of Chemistry, Classification of Elements, Chemical Bonding, Equilibrium and Redox Reactions form the base for Class 12 topics such as electrochemistry, Chemical Kinetics, p-block and d-block elements. Understanding formulas, units, mole concept and valency rules in Class 11 will make the Cbse Class 12 Chemistry syllabus much easier to handle.

List of Units in CBSE Class 11 Chemistry Syllabus 2025-26

The units mentioned in the official Cbse Class 11 Chemistry syllabus are as follows. Students should keep their notebook index and reading schedule aligned with the order given here.

UNIT I – Some Basic Concepts of Chemistry

UNIT II – Structure of Atom

UNIT III – Classification of Elements and Periodicity in Properties

UNIT IV – Chemical Bonding and Molecular Structure

UNIT V – Chemical Thermodynamics

UNIT VI – Equilibrium

UNIT VII – Redox Reactions

UNIT VIII – Organic Chemistry: Some Basic Principles and Techniques

UNIT IX – Hydrocarbons

For each unit, students should first read the NCERT textbook carefully, underline key definitions and laws, prepare short notes of formulas and important points and then solve all in-text and back exercise questions. After completing a unit, revising it through sample papers and previous year question papers helps in understanding the exam pattern and question framing style.

CBSE Class 11 Chemistry Practical Syllabus 2025-26 with Marking Scheme

Along with theory, CBSE Class 11 Chemistry also includes a detailed practical component. The practical exam familiarises students with lab equipment, observation skills, experimental techniques and error analysis. The marking scheme for practicals is given below.

The table shows that Volumetric Analysis and Salt Analysis together carry 16 marks, so students must be comfortable with preparing standard solutions, using burettes and pipettes, and identifying basic radicals and acid radicals. Maintaining a neat practical record throughout the year and completing the assigned project work can help secure full marks in the internal assessment part.

Regular practice in the lab under teacher supervision, writing balanced chemical equations for each experiment, and revising viva questions from the record book are crucial steps to score well in the 30-mark practical examination. Good performance in practicals also strengthens conceptual understanding of theory topics like acids and bases, redox reactions, solubility, pH and solutions.

CBSE Syllabus for Class 11 Chemistry Practical 2025-26

The Chemistry practical syllabus includes hands-on activities related to pH measurement, water quality testing, evaporation, soap foaming, acidity of tea and fruit juices and many more real-life based experiments. Some of the activities are:

• Determination of pH of some solutions obtained from fruit juices, solution of known and varied concentrations of acids, bases and salts using pH paper or universal indicator.
• Comparing the pH of solutions of strong and weak acids of same concentration.
• Study the pH change in the titration of a strong base using universal indicator.

• Checking the bacterial contamination in drinking water by testing sulphide ion.
• Study of the methods of purification of water.
• Testing the hardness, presence of Iron, Fluoride, Chloride, etc., depending upon the regional variation in drinking water and study of causes of presence of these ions above permissible limit (if any).
• Investigation of the foaming capacity of different washing soaps and the effect of addition of Sodium carbonate on it.
• Study the acidity of different samples of tea leaves.
• Determination of the rate of evaporation of different liquids and study the effect of acids and bases on the tensile strength of fibres.
• Study of acidity of fruit and vegetable juices.

These activities connect textbook concepts to everyday life and make Chemistry more interesting. Students should carefully note down observations, record data in tables and write clear inferences. This habit supports both lab performance and theory answers in the board exams where experiment-based questions are frequently asked.
