JEE Main 2025 Important Topics for Chemistry

JEE Mains has equal weightage for each subject which is 100 marks for each subject consisting of 25 questions across 2 papers. Chemistry is often considered easy compared to mathematics, and physics. However, it is advised not to ignore the subject as the competition for 2025 will be higher compared to previous years.

Here are some important topics for chemistry:

• Atomic Structure
• Electrochemistry
• Gaseous & Liquid State
• Chemical Bonding
• Nuclear & Surface Chemistry
• Chemical Kinetics
• Aromatic Compounds
• Co-ordination Compound
• d-Block Elements
• General Organic Chemistry
• Thermodynamics
• p-Block Elements
• Alkyl Halides
• Carboxylic Acids & Its Derivatives
• Aldehydes and Ketones
• Isomerism

Tips to Prepare for JEE Main 2025: Chemistry

Physical Chemistry: Maintaining short notes for quick revision for chapters like atomic structure, ionic equilibrium, and thermochemistry can help you save a lot of time. Questions from this topic will often involve applying the learned concepts, practicing applying formulas, and noting down all the important formulas for practice.

Organic Chemistry: Candidates should focus on key name reactions like Ozonolysis, Aldol, Cannizzaro, Perkin, and Hoffmann’s, along with their mechanisms. Special attention should be given to General Organic Chemistry (GOC), particularly the stability of reaction intermediates and concepts of acidity and basicity. Detailed study of isomerism, organic compounds with oxygen, and functional group tests is also essential.

In-Organic Chemistry: Candidates should maintain a diary to note important details such as ore formulas and alloy compositions, which frequently appear in objective tests. Additionally, emphasis should be placed on chapters like chemical bonding, p-block elements, and coordination chemistry, as these areas typically account for a significant portion of the questions.

JEE Main 2025 Important Topics for Mathematics

Mathematics subject often demands a lot of time from candidates for practice. Although it is advised to finish the syllabus at least once, candidates should focus on important topics if the time is limited.

Here are some important topics from mathematics subject.

• Vectors
• Determinant & Matrices
• 3 Dimensional Geometry
• Sequence & Series
• Definite Integral & Area Under the Curve
• Probability Distribution (Binomial Mean & Variance)
• Circle
• Application of Derivatives
• Straight Line
• Conic Sections
• Limits, Continuity & Differentiability
• Binomial Theorem & M. I.
• Complex Number
• Quadratic Equation
• Functions

Tips to Prepare for JEE Main 2025: Mathematics

• Trigonometry: involves complex formulas and equations so focus more on these topics by splitting your formulas into several sections and practicing them.
• Coordinate Geometry:  focus on understanding the formulas and identifying similarities between them to aid recall during the exam. Don’t overlook geometric properties, especially for straight lines and circles; make sure to include these in your notes as well.

• Algebra: Focus on properties and symmetric sums of roots in quadratic equations. Revise complex numbers geometrically and study Binomial, Permutation, Combination, and Probability together, practicing typical problems for problem-solving strategies.

• Calculus: Master standard limits, differentiation formulas, and integration results. Also, review Continuity, Differentiability, and properties of Definite Integration.
• Vector and 3-D Geometry: Study these together as they are closely related, with emphasis on standard formulae for problem-solving.
