What Each Chapter of the NCERT Class 10 Chemistry Book in Hindi Covers

Each chapter below follows the CBSE 2026-27 syllabus wording. Learn the key terms in both Hindi and English, since Hindi-medium papers use the Hindi terms with English in brackets.

अध्याय 1 — रासायनिक अभिक्रियाएँ एवं समीकरण (Chemical Reactions and Equations)

This chapter teaches how to write and balance a chemical equation and how to identify the type of a reaction. It covers संयोजन (combination), वियोजन (decomposition), विस्थापन (displacement), द्विविस्थापन (double displacement), precipitation, exothermic and endothermic reactions, and उपचयन-अपचयन (oxidation-reduction).

अध्याय 2 — अम्ल, क्षारक एवं लवण (Acids, Bases and Salts)

Acids give H⁺ ions and bases give OH⁻ ions in water. You study indicators, neutralisation, the pH scale and why pH matters in daily life, plus the preparation and uses of sodium hydroxide, bleaching powder, baking soda, washing soda and plaster of Paris.

अध्याय 3 — धातु एवं अधातु (Metals and Non-metals)

This chapter compares the physical and chemical properties of metals and non-metals, builds the अभिक्रियाशीलता श्रेणी (reactivity series), and explains ionic compounds, basic metallurgy and संक्षारण (corrosion) and its prevention.

अध्याय 4 — कार्बन एवं उसके यौगिक (Carbon and its Compounds)

Carbon forms covalent bonds and a huge variety of compounds. The chapter covers saturated and unsaturated hydrocarbons, समजातीय श्रेणी (homologous series), naming of alkanes, alkenes, alkynes and functional groups, combustion, oxidation, addition and substitution reactions, ethanol and ethanoic acid, and soaps and detergents.

Class 10 Chemistry Syllabus 2026-27 and Marks (CBSE)

Chemistry is Unit I of CBSE Class 10 Science, "Chemical Substances – Nature and Behaviour", worth 25 of the 80 theory marks in 2026-27 — the joint-highest unit with Biology. The NCERT Class 10 Chemistry book in Hindi covers this unit completely.

CBSE does not publish a chapter-wise split of the 25 marks, so avoid any page that quotes exact marks per chapter.

Is Periodic Classification of Elements in the Class 10 syllabus?

Only for school-level (formative) assessment. CBSE's 2026-27 curriculum lists तत्वों का आवर्त वर्गीकरण (Döbereiner's triads, Newlands' octaves, Mendeleev's and the Modern Periodic Table) as a topic that is taught but not assessed in the board exam. It is not a chapter in NCERT's current विज्ञान book; CBSE supplies reading material for it.

Chemistry practicals in Class 10 Science 2026-27

Five of the prescribed experiments are from chemistry:

1. Finding the pH of dilute HCl, dilute NaOH, dilute ethanoic acid, lemon juice, water and dilute hydrogen carbonate solution; and studying acids and bases with litmus, zinc and sodium carbonate.
2. Performing and classifying combination, decomposition, displacement and double displacement reactions.
3. Observing the action of Zn, Fe, Cu and Al on their salt solutions and arranging them by reactivity.
4. Studying the odour, solubility, litmus test and reaction with sodium hydrogen carbonate of ethanoic acid.
5. Comparing the cleaning capacity of soap in soft and hard water.

Question paper design for Class 10 Science 2026-27

The 80-mark theory paper tests knowledge and understanding (50%), application (30%) and analysis/evaluation (20%), with about 33% internal choice. Question types include objective, assertion-reason, short answer, long answer and case-based questions. Internal assessment (20) = periodic assessment 5 + multiple assessment 5 + portfolio 5 + practical work 5.

How to Study the NCERT Class 10 Chemistry Book in Hindi for Full Marks

The 25 chemistry marks are the most scoring in Class 10 Science because questions stay close to NCERT text, equations and activities. Follow this order:

1. Start with Chapter 1. Balancing equations is used in every later chapter.
2. Make a formula sheet of the 5 salts in Chapter 2 and the reactivity series in Chapter 3.
3. Practise electron-dot structures daily for Chapter 4 — they appear almost every year.
4. Do every क्रियाकलाप (activity) in the book; case-based questions are built on them.
5. Solve in-text and exercise questions, then check with NCERT solutions.
6. Finish with past board papers under a 3-hour timer
