ICSE CLASS 11 CHEMISTRY SYLLABUS

Question Paper Design:

Since Class 11th Chemistry is divided into theory and a practical section. Therefore, there are held two separate exams in chemistry i.e., ‘Theory Exam’ and ‘Practical Exam’.

Scheme For Theory Examination [70 Marks]:

The theory exam is held for total 70 marks with a maximum time limit of 3 hours given to attempt it. The question paper of the theory exam consists of four types of questions, which is listed below.

  • Question 1 is of twenty marks having four sub parts all of which are compulsory.
  • Question numbers 2 to 8 carry 2 marks with two questions having internal choice.
  • Question numbers 9 to 15 carry 3 marks with two questions having internal choice.
  • Question numbers 16 to 18 carry 5 marks each. Each question has an internal choice.

3

Analysing, Evaluating and Creating: Examine and break information into parts by identifying motives or causes. Make inferences and find evidence to support generalizations. Present and defend opinions by making judgments about information, validity of ideas or quality of work based on a set of criteria. Compile information together in a different way by combining elements in a new pattern or proposing alternative solutions.

Practical Exam [15Marks]:

Micro-chemical methods are available for several of the practical experiments. Wherever possible techniques should be used.

Project Work [10 Marks]:

The candidate is to creatively execute one project/assignment on a selected topic of Chemistry. Teachers may assign or students may choose any one project of their choice.

Suggested Evaluation criteria for Project Work:

  • Introduction / purpose
  • Contents
  • Analysis/ material aid (graph, data, structure, pie charts, histograms, diagrams, etc)
  • Presentation
  • Bibliography

Practical File [05 Marks]:

Teachers are required to assess students based on the Chemistry Practical file maintained by them during the academic year.
