Frequently Asked Questions
Q1. Which chemistry has more weightage in JEE Mains?
Answer: In JEE Mains, Organic Chemistry and Inorganic Chemistry carry the maximum weightage with approximately 35% each of the Chemistry paper.
- Inorganic Chemistry (for example, Transition Elements, Coordination Compounds, Periodic Table) carries approximately 35% weightage.
- Organic Chemistry (for example, Biomolecules, Carboxylic Acids, Hydrocarbons) also accounts for 30-35%.
- Physical Chemistry (e.g., Thermodynamics, Electrochemistry, Chemical Kinetics) contributes approximately 25-30%.
Q2. What is the toughest chapter in chemistry for JEE?
Answer: The most challenging chapters in Chemistry for JEE have the following approximate weightage:
Coordination Compounds (Inorganic Chemistry):
- Weightage: 9.9% (approximately 3-4 questions)
- This chapter is important for understanding complex geometry and bonding, which is usually considered difficult because of the depth of the subject.
Chemical Bonding and Molecular Structure (Inorganic Chemistry):
- Weightage: 6.6% (approximately 2 questions)
- A difficult topic because of the fine understanding needed in concepts such as hybridization, molecular orbital theory, and polarity of the bond.
Chemical Kinetics (Physical Chemistry):
- Weightage: 3.3% (approximately 1 question)
- Chemical kinetics is challenging because it deals with reaction rates, activation energy, and intricate calculations involving rate laws.
Thermodynamics (Physical Chemistry):
- Weightage: 6.6% (approximately 2 questions)
- This subject includes important concepts like entropy, enthalpy, and Gibbs free energy, which demand problem-solving and thorough conceptual understanding.
Q3. Are PYQs repeated in JEE Mains?
Answer: No, PYQs are not repeated as such in JEE Mains. Whereas, the concept and nature of questions from previous years tend to return in some other form.
- JEE Mains generally attempts to test the same fundamental subjects every year, so PYQs make you familiar with the pattern of the exam and commonly tested concepts.
- While the precise questions are not recycled, the difficulty, question style, and conceptual emphasis are frequently the same.
Q4. Coordination Compounds JEE Mains weightage
Answer: The Coordinate Compounds in the JEE Main holds approximately 9.9% weightage, which corresponds to about 3-4 questions in the exam.
Coordinate Chemistry is the part of inorganic Chemistry, the topics like coordination number, ligand types, isomerism, and bonding in coordination compounds are important to understand.
Q5. Coordination Compounds JEE Mains Notes
Answer: Coordination Compounds is an important concept in Inorganic Chemistry for JEE Mains. Coordination Compounds consist of a central metal atom or ion bonded to the surrounding ligands by coordinate bonds. These compounds have significant applications in various fields, including catalysis, medicine, and material science.
