Question

How to study chemistry of class 12 for both boards and her mains.
Please give good suggestions.

Thank you ​

Answer 1

Segregrate all the topics according to their marks distribution and go topic wise only.

As we all have different strategy to study but the best way out is revision and only revision especially of the following topics:

Name reactions
Conversion chart
Unit 1: Solid State –
Classification of solids based on different binding forces

(Molecular, ionic, covalent and metallic solids)

Questions based on Metallic solids are expected this year
Unit cell in two dimensional and three dimensional lattices

Calculation of number of atoms per unit cell is expected
Calculation of density of unit cell

Numerical problems are expected
Packing in solids

Questions based on packing efficiency, calculation of radius etc. are also expected
Electrical and magnetic properties

Band theory of Metals, Conductors, Semiconductors and Insulators and n & p type semiconductors

Question based on electron sea model are expected
Unit 2: Solutions –

Types of solutions

One mark question based on types of solutions are expected e.g., Alloy is an example of solid in solid solution
Henry’s law – Questions related to Henry’s law are frequently asked in CBSE Class 12 Chemistry board exam

Solubility of gases in liquids

How it changes with changes in temperature etc.
Colligative properties

Raoult's law (Important)

Relative lowering of vapour pressure (Numerical problems are expected)

Depression of freezing point (Theoretical questions on applications & numerical problems are expected)

Elevation of boiling point (Numerical problems are expected)

Osmotic pressure

Determination of molecular masses using colligative properties (Numerical problems are expected)

Abnormal molecular mass

Van't Hoff factor

When it is less than 1 and when it is greater than 1
