# Chemistry — NCERT Class 11 — CBSE (NCERT textbooks) — Shishya school context > Subject page: https://shishya.in/schooling/cbse/class-11/chemistry · class: https://shishya.in/schooling/cbse/class-11 (context: https://shishya.in/schooling/cbse/class-11/context.md) · data as of 2026-10-11 (IST). Free to cite; link back to the subject page. > Honesty: Shishya never reproduces, summarises or translates textbook text — read a chapter at its official link. Practice questions are Shishya's own, written by AI and answer-checked before they are shown; they are not NCERT exercises, not board questions and not previous-year questions. A chapter marked "not ready yet" has no Shishya notes or practice, and its Shishya page is not linked here. > Children: Class 1-7 school pages have no chat tutor, offer no sign-in and ask no child to create an account. On Class 8-12 pages a student may sign in to save practice to an account — for students 13 and above; no school page asks anyone their age or role — and anyone can read a chapter, take its practice where the chapter has one and ask the AI tutor about it without signing in; the tutor says it is an AI and answers study questions only, with a daily message limit. The 5-question practice on the chapter pages that have it needs no account, and no result is saved to any account or profile from it: Shishya records only an anonymous usage event (which chapter was practised and the score) — on Class 8-12 pages with the same cookie-based analytics every page view sends, on Class 1-7 pages with no cookie, account or other visitor identifier. A signed-in student's own practice set is saved to that account. ## Chemistry - Book: Chemistry Part-I — https://ncert.nic.in/textbook.php?kech1=0-6 (NCERT also lists Hindi, Urdu editions) - Book: Chemistry Part II — https://ncert.nic.in/textbook.php?kech2=0-3 (NCERT also lists Hindi, Urdu editions) - Chapters (9; 9 with Shishya notes, 9 with answer-checked practice of 5+ questions): - Unit 1 — Some Basic Concepts of Chemistry — Shishya notes + 37 answer-checked practice questions: https://shishya.in/schooling/cbse/class-11/chemistry/some-basic-concepts-of-chemistry · official PDF: https://ncert.nic.in/textbook/pdf/kech101.pdf - Unit 2 — Structure of Atom — Shishya notes + 37 answer-checked practice questions: https://shishya.in/schooling/cbse/class-11/chemistry/structure-of-atom · official PDF: https://ncert.nic.in/textbook/pdf/kech102.pdf - Unit 3 — Classification of Elements and Periodicity in Properties — Shishya notes + 38 answer-checked practice questions: https://shishya.in/schooling/cbse/class-11/chemistry/classification-of-elements-and-periodicity-in-properties · official PDF: https://ncert.nic.in/textbook/pdf/kech103.pdf - Unit 4 — Chemical Bonding and Molecular Structure — Shishya notes + 40 answer-checked practice questions: https://shishya.in/schooling/cbse/class-11/chemistry/chemical-bonding-and-molecular-structure · official PDF: https://ncert.nic.in/textbook/pdf/kech104.pdf - Unit 5 — Thermodynamics — Shishya notes + 38 answer-checked practice questions: https://shishya.in/schooling/cbse/class-11/chemistry/thermodynamics · official PDF: https://ncert.nic.in/textbook/pdf/kech105.pdf - Unit 6 — Equilibrium — Shishya notes + 37 answer-checked practice questions: https://shishya.in/schooling/cbse/class-11/chemistry/equilibrium · official PDF: https://ncert.nic.in/textbook/pdf/kech106.pdf - Unit 7 — Redox Reactions — Shishya notes + 37 answer-checked practice questions: https://shishya.in/schooling/cbse/class-11/chemistry/redox-reactions · official PDF: https://ncert.nic.in/textbook/pdf/kech201.pdf - Unit 8 — Organic Chemistry – Some Basic Principles and Techniques — Shishya notes + 39 answer-checked practice questions: https://shishya.in/schooling/cbse/class-11/chemistry/organic-chemistry-some-basic-principles-and-techniques · official PDF: https://ncert.nic.in/textbook/pdf/kech202.pdf - Unit 9 — Hydrocarbons — Shishya notes + 39 answer-checked practice questions: https://shishya.in/schooling/cbse/class-11/chemistry/hydrocarbons · official PDF: https://ncert.nic.in/textbook/pdf/kech203.pdf - Shishya content last updated: 2026-10-03 ## Other subjects in this class - Sanskrit: https://shishya.in/schooling/cbse/class-11/sanskrit - Accountancy: https://shishya.in/schooling/cbse/class-11/accountancy - Mathematics: https://shishya.in/schooling/cbse/class-11/mathematics - Biology: https://shishya.in/schooling/cbse/class-11/biology - Psychology: https://shishya.in/schooling/cbse/class-11/psychology - Geography: https://shishya.in/schooling/cbse/class-11/geography - Physics: https://shishya.in/schooling/cbse/class-11/physics - Hindi: https://shishya.in/schooling/cbse/class-11/hindi - Sociology: https://shishya.in/schooling/cbse/class-11/sociology - English: https://shishya.in/schooling/cbse/class-11/english - Political Science: https://shishya.in/schooling/cbse/class-11/political-science - History: https://shishya.in/schooling/cbse/class-11/history - Economics: https://shishya.in/schooling/cbse/class-11/economics - Business Studies: https://shishya.in/schooling/cbse/class-11/business-studies - Urdu: https://shishya.in/schooling/cbse/class-11/urdu - Home Science: https://shishya.in/schooling/cbse/class-11/home-science - Creative Writing and Translation: https://shishya.in/schooling/cbse/class-11/creative-writing-and-translation - Fine Art: https://shishya.in/schooling/cbse/class-11/fine-art - Informatics Practices: https://shishya.in/schooling/cbse/class-11/informatics-practices - Computer Science: https://shishya.in/schooling/cbse/class-11/computer-science - Health and Physical Education: https://shishya.in/schooling/cbse/class-11/health-and-physical-education - Biotechnology: https://shishya.in/schooling/cbse/class-11/biotechnology - Sangeet: https://shishya.in/schooling/cbse/class-11/sangeet - Knowledge Traditions Practices of India: https://shishya.in/schooling/cbse/class-11/knowledge-traditions-practices-of-india
