Chemistry can guarantee you assured marks in JEE Advanced/JEE Mains, on the off chance that you have prepared well. Most of the times, questions in JEE Chemistry are not especially twisted and get tested directly. The key to solving problems of chemistry lies in understanding basic concepts clearly. Here, we’ll tell you about how to improve your JEE chemistry score!
You cannot think of solving all types of Chemistry problems without having a solid conceptual foundation. Memorizing theories and concepts doesn’t help you to develop problem-solving skills. Always keep in mind, all three parts (Physical, Organic, and Inorganic) of Chemistry are interconnected — you cannot ignore any part. You must have a strong understanding of each part if you want to a good JEE Chemistry score.
Before starting, I would suggest you paste the periodic table in your study room. Start with Physical Chemistry first and then start inorganic and organic section.
You must understand that it is very important to read as much as possible in order to learn JEE Chemistry. Also, there is a possibility of forgetting things, so revision is a must. You must consider Chemistry as seriously as Mathematics and Physics. With appropriate planning, you can achieve a great JEE Chemistry score.
- NCERT: This is for sure the most important book for JEE Chemistry. You should be comfortable with every line of NCERT in each of the Inorganic, Physical and Organic part to get a good JEE chemistry score. Most of the Inorganic questions are asked directly without any twist — so you should mug up each and every reaction, properties, and examples.
- Organic chemistry (O P Tandon): It is one of the best books for JEE Chemistry. It builds the concepts from very basic level to advanced level. The new edition is in accordance with the new pattern of JEE Advanced.
- Inorganic Chemistry: NCERT chemistry textbook would be more than enough for JEE Main as well as JEE Advanced. But if want deep knowledge on any topic, refer J D Lee Inorganic chemistry, which is available online in pdf version.
- Physical Chemistry (P. Bahadur): Best book for physical chemistry. It contains good theory as well as a large number of solved examples. It has varieties of numerical to make your concepts strong and would help you to get a good JEE chemistry score.
To complete your preparation for getting a good JEE chemistry score, you are required to solve the past year JEE Chemistry paper (39 years Chapterwise Solved Paper by Arihant Publications).
- Mole Concept: You must read this chapter to gain a firm command over the entire JEE chemistry. Practice some questions on Concentration terms such as Mole fraction, Normality, Morality, Molality, %(w/w), %(w/v) etc.
- Chemical Bonding: It is basic chapter whose concepts are used in entire organic chemistry. Direct questions are always asked from Dipole moment, Hybridisation and VSEPR theory.
- Atomic structure: Questions are frequently asked from Quantum numbers, De Broglie Hypothesis, Heisenberg’s Uncertainty Principle and Spectrum of a Hydrogen atom.
- Chemical kinetics: Pay special attention to 1st order reactions
- Chemical Equilibrium: Le Chatelier’s principle (effect of temperature, concentration and pressure).
- Electrochemistry: Nernst equation and its relation, Electrochemical series, E.M.F of Galvanic cells, Faraday’s laws of electrolysis, Electrolytic conductance, Kohlrausch’s law. Very important chapter for paragraph type questions.
- General organic chemistry(GOC): The key to understanding the entire organic chemistry is being through with the GOC section.
- Named Reactions: A large portion of organic chemistry consist of standardly named reactions and you are expected to know these reactions along with the complete mechanisms.
- Electrophilic aromatic substitution reaction of Benzene and its derivatives: Standard reactions and named reactions are the most important. Direct questions are always asked from this topic.
- Few problems of organic chemistry in JEE Mains/Advanced are based on organic synthesis where you are expected to identify the missing products/reagents. Hence, you are required to practice these types of problems a lot if you want to get a good JEE chemistry score.
- Aldehyde & Ketones: There is a very high probability of occurrence of at least one question from each Aldol condensation and Cannizzaro’s reaction.
All chapters hold equal importance. No chapter can be considered less or more important. Few extremely important topics are:
- Classification of Elements & periodicity in their properties.
- Coordination compounds: Stereoisomerism of coordination compounds, Werner Theory, Geometry and shapes of Tetrahedral and Octahedral complexes, Crystal field theory and its applications.
- p block: This is one of the most important topics. Learn each and every line of p block from NCERT, sometimes physical properties (colour, solubility, hardness) of compounds are also asked in JEE Main.
- Metallurgy and ores: Mainly standard questions are asked from NCERT. Carbon reduction method (tin and iron), Self-reduction method ( lead and copper), Electrolytic reduction method (aluminum and magnesium), Cyanide process ( gold and silver).
- In the Inorganic chemistry, exceptions are very important because many questions in the JEE Main and JEE Advanced are based on exceptions.
Some basic tips
- The NCERT chemistry book contains all the relevant matter along with basic and easy questions. They help in laying the conceptual groundwork and in increasing your confidence. This is more than enough as far as JEE Mains is concerned. Once you grasp all the concepts you can move over to the Advanced Problems.
- Don’t try to learn reactions (especially for organic chemistry). It is not a decent practice. Try to understand the complete mechanism behind it.
- You should memorize all the formulas of Mole concept, Chemical kinetics, Equilibrium, and Electrochemistry. Solving lots of problems on these topics makes your numerical approach strong.
- You need to note down important formulae & reactions (named reactions in organic) separately. Revising these will enable you to review everything from your subliminal memory.
- Questions related to a comparison of acidity, basicity, and reactivity between different organic compounds are very common in JEE Chemistry.
- In JEE Chemistry, few questions are asked from practicals (Salt analysis, volumetric analysis etc). If you have done practicals in school then you will be able to answer. Otherwise, refer to lab manual or Vogel’s Qualitative Inorganic Analysis.
- Chemical Bonding and Coordination Compounds are those chapters where most of the questions are related to processes, structure, and applications. Special attention must be given to these chapters.
- Questions of organic chemistry are slightly tough and it would be a good idea to solve them at the end after finishing the questions of physical and inorganic chemistry unless you have very good command on it.
- For numerical questions (especially in physical chemistry), you must revise shortcut formulas which would enable you to arrive at the answer quickly, and hence save time. If you face problem in remembering the particular formula, have a look at its logic or derivation so that you can derive it on your own when needed.
- When you get stuck in any question (particularly in single correct type) then, try to make guesses by eliminating the options. Try to reach the question statement by assuming each option to be the correct answer one by one, and check whether it satisfies the problem statement or not.
Chapters included in JEE Main but not in JEE Advanced
You will get at least one question from each of these chapters in JEE Mains. As these chapters are not included in JEE Advanced Syllabus, so you need not put extra effort in them. NCERT would be more than enough.
- Biomolecules: Vitamins, Nucleic acids (Chemical constitution of DNA and RNA)
- Chemistry in Everyday Life: Chemicals in Medicines, Chemicals in food (Preservatives, artificial sweetening agents), Cleansing agents (Soaps and detergents, cleansing action).
Last minute tips
- Solve mock test papers for JEE Main and JEE Advanced, as well as Previous Years’ JEE Main and JEE Advanced Question Papers, or join any Test Series which you find more suitable.
- Stay motivated. You may score high or low in practice/mock tests, but what is truly important is to keep studying consistently for the final exam.
- As you are preparing for JEE exam, it’s obvious that stress may kick in. But the challenge lies in keeping stress behind and maintaining a positive mindset. Stay positive to work towards achieving your goal.
