ISC Class 12 Chemistry

ISC Class 12 Chemistry (862) has a 3-hour theory paper worth 70 marks and a practical component worth 30 marks: a 3-hour practical exam (15), project work (10) and a practical file (5). Our ISC Class 12 Chemistry course follows the CISCE syllabus for the ISC (Classes 11 and 12): solutions, electrochemistry, chemical kinetics, the d- and f-block elements, coordination compounds, haloalkanes and haloarenes, alcohols, phenols and ethers, aldehydes, ketones and carboxylic acids, amines and biomolecules. Lessons are live and one-to-one with a verified subject teacher, who explains each concept clearly, works through textbook and specimen-paper questions with you and shows you how CISCE examiners award marks. It prepares you for the ISC board exam and the practical. Suitable for students in India and at CISCE schools abroad, with lesson times in IST.

What is ISC Class 12 Chemistry?

In short: this course gives one-to-one online tutoring for ISC Class 12 Chemistry. A verified tutor explains every chapter, works through textbook exercises and sample-paper questions step by step, and builds the exam technique you need for the board exam.

ISC Class 12 Chemistry is part of the Indian School Certificate, the senior secondary qualification set by CISCE (the Council for the Indian School Certificate Examinations). The ISC Class 12 exam is a CISCE board exam, usually held in February and March.

This course covers the full syllabus one to one with a verified chemistry tutor.

For wider support, see our chemistry tutoring page, or revisit the foundations in the ISC Class 11 Chemistry course.

How is ISC Class 12 Chemistry assessed?

ISC Class 12 Chemistry follows the CISCE (ISC) syllabus. Class 12 ends with the board examination, set by CISCE, alongside internal or practical assessment where the subject includes it. Marks, durations and question types can change from year to year, so check the current CISCE regulations and syllabus for your exam year. Tutors follow the textbook chapters your school teaches and practise the question styles in recent sample papers.

Which topics are in the ISC Class 12 Chemistry syllabus?

BranchKey topics
Physical chemistrySolutions; electrochemistry; chemical kinetics
Inorganic chemistryd- and f-block elements; coordination compounds
Organic chemistryHaloalkanes and haloarenes; alcohols, phenols and ethers; aldehydes, ketones and carboxylic acids; amines; biomolecules

How do you master ISC organic chemistry?

  1. Learn reaction mechanisms, not just products.
  2. Build a chart of named reactions and conversions.
  3. Learn distinguishing tests between compounds.
  4. Practise IUPAC naming.
  5. Solve specimen and previous years' papers.

What does a worked chemistry question look like?

Here is a typical mole concept question: how many moles are in 8.8 g of carbon dioxide? (C = 12, O = 16.)

StepWorking
Molar mass of CO₂12 + 2 × 16 = 44 g/mol
Moles8.8 ÷ 44 = 0.20 mol
Molecules0.20 × 6.022 × 10²³ ≈ 1.2 × 10²³

Where do students lose marks in ISC Class 12 Chemistry?

Students most often lose marks through the habits below. Each is easy to fix with regular practice and feedback.

Mark-loserWhat to do instead
Unbalanced equationsBalance every equation
Mole calculations without unitsShow units and steps
Organic names wrongFollow IUPAC rules step by step
Reactions memorised without mechanismLearn why reactions happen
Practical answers vagueName the test and the observation

Textbooks, specimen papers and exam technique

CISCE examiners reward precise answers, correct terminology and neat, well-labelled working. Tutors use your school's textbooks, the CISCE specimen papers and previous years' papers, and teach you to write answers that match the marks allotted. Tutors also help you understand the theory behind your practical experiments and project; the project you submit must be your own work.

How the lessons work

Lessons are live and one to one on video with a shared whiteboard, at times that suit students in India and abroad. Your tutor follows the latest CISCE syllabus and your school's schedule. See also ISC Class 11 Chemistry, CBSE Class 12 Chemistry and our Chemistry subject page.
