sir can u tell jee 2021 portion

Dear aspirant
Jee exam has vast syllabus . It includes the total syllabus of 11th and 12th in PCM.
The chapters having more weightage are
Maths :
Calculus: Application of derivatives ,definite and indefinite integrals , application of integrals .
Algebra : Vector and 3d ( most important) , sequence and series , complex numbers, Matrix and determinants .
Coordinate geometry: Circle , parabola and straight lines . Questions from these section is easy .
Trigonometry and probability .

Chemistry

1. Physical chemistry: 30 % of the questions comes from this section Chemical Equilibrium, Atomic Structure, Chemical Kinetics, Electrochemistry, Gaseous State, Ionic Equilibrium, Mole Concept, Nuclear Chemistry, Redox reactions, Solid State, Solution, and thermodynamics.
2. Organic : 45 % of the questions comes from this section . Haloalkanes, Haloarenes and Phenols, Hydrocarbons, Isomerism, Nitrogen Compound and Aliphatic Amines, Practical and Environmental Chemistry, Alkyl Hallide, Aromatic Compounds, Carbonyl Compounds, Grignard Reagent, Ozonolysis are important .
3. Inorganic : Questions from inorganic part is always  easy to solve . So,one must complete the whole syllabus from inorganic chemistry .

Physics :
Optics and modern physics
Electrostatics, Current Electricity, Magnetic Effects of Current and Magnetism, Electromagnetic Induction and Alternating Currents, Electromagnetic Waves
Mechanics
