CBSE Class 12 Chemistry Syllabus for 2022-23

On April 21st, 2022, CBSE released a reduced syllabus for classes 9 to 12 of the 2022-23 academic session.

After so many changes in the last 2 to 3 years, CBSE has finalised a reduced syllabus for Class 10 teachers and students to follow. However, the term-based examination pattern will NOT BE FOLLOWED in 2022-23.

We, at Educart, were prompt about it and have updated the changes in all the subjects for you. Here, you can find:

  • PDF download links to the latest reduced Class 12 Chemistry Syllabus for 2022-23 academic session; and
  • simple analysis of all the deleted topics/ chapters to be followed this year.

With all this information in hand, both teachers and students will have a defined structure to begin the learning process on time and efficiently.

PRACTICALS

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

A. Surface Chemistry

  1. Preparation of one lyophilic and one lyophobic sol
  • Lyophilic sol - starch, egg albumin and gum
  • Lyophobic sol - aluminium hydroxide, ferric hydroxide, arsenious sulphide.
  1. Dialysis of sol-prepared in (a) above.
  2. Study of the role of emulsifying agents in stabilising the emulsion of different oils.

B. Chemical Kinetics

  1. Effect of concentration and temperature on the rate of reaction between Sodium Thiosulphate and Hydrochloric acid.
  2. Study of reaction rates of any one of the following:
  • Reaction of Iodide ion with Hydrogen Peroxide at room temperature using different concentrations of Iodide ions.
  • Reaction between Potassium Iodate, (KIO3) and Sodium Sulphite: (Na2SO3) using starch solution as an indicator (clock reaction).

C. Thermochemistry

Any one of the following experiments

  1. Enthalpy of dissolution of Copper Sulphate or Potassium Nitrate.
  2. Enthalpy of neutralisation of strong acid (HCI) and strong base (NaOH).
  3. Determination of enthalpy change during interaction (Hydrogen bond formation) between Acetone and Chloroform.

D. Electrochemistry

Variation of cell potential in Zn/Zn2+|| Cu2+/Cu with change in concentration of electrolytes (CuSO4 or ZnSO4) at room temperature.

E. Chromatography

  1. Separation of pigments from extracts of leaves and flowers by paper chromatography and determination of Rf values.
  2. Separation of constituents present in an inorganic mixture containing two cations only (constituents having large difference in Rf values to be provided).

F. Preparation of Inorganic Compounds

Preparation of double salt of Ferrous Ammonium Sulphate or Potash Alum. Preparation of Potassium Ferric Oxalate.

G. Preparation of Organic Compounds

Preparation of any one of the following compounds

  1. Acetanilide

  3. p-Nitroacetanilide
  4. Aniline yellow or 2-Naphthol aniline dye.

H. Tests for the functional groups present in the organic compounds: Unsaturation, alcoholic, phenolic, aldehydic, ketonic, carboxylic and amino (Primary) groups.

I. Characteristic tests of carbohydrates, fats and proteins in pure samples and their detection in given foodstuffs.

J. Determination of concentration/ molarity of KMnO4 solution by titrating it against a standard solution of:

  1. Oxalic acid,
  2. Ferrous Ammonium Sulphate (Students will be required to prepare standard solutions by weighing themselves).

K. Qualitative analysis
