Chemistry Strategy
Chemistry is allegedly the make-or-break subject in IIT JEE preparation. Most students who are naturally inclined to math or physics seem to be wary of chemistry. Too many exceptions and the amount of memorization required, especially in inorganic chemistry, could be the reasons for the same. Yet, with a different strategy for different sections, one can also do well in the subject:
Physical Chemistry:
Stoichiometry:The most important chapter in physical chemistry is stoichiometry. You will find the rest of this preparation in this section to be more accessible if you understand the principles of it. This will enable you to master all the Chemistry material for JEE. Practice and gain a good hold of concepts like Molality, Normality, Morality, and Mole fraction.
Chemical Bonds: The chapter on chemical bonds addresses concepts of molecules. Molecules represent the smallest unit of a complex, and the principle developed in them can be applied to all aspects of organic chemistry. Issues related to dipole moment, hybridization, and VSEPR theory are always directly questioned. You should focus your efforts in understanding how valence electrons are transferred in different types of bonds.
Chemical Equilibrium: This is actually one of the easiest chapters. Because some questions are conceptual in nature, such as those based on Le Chatelier's principle (impact of temperature, concentration, and pressure), be sure to read the theory section in addition to the numerical.
Atomic structure: Heisenberg's Uncertainty Principle, the De Broglie Hypothesis, quantum numbers, and the spectrum of a hydrogen atom are some of the common topics of questions. This chapter is believed to make plenty of sense. Previous trends suggest that questions on this topic come with an easy-to-moderate difficulty level. Common queries should be practiced.
Chemical kinetics: First-order reactions require particular attention in chemical kinetics. It is one of the simpler chapters because the topics included in the JEE form are likewise not that challenging.
Thermodynamics: This chapter is thought to be challenging. If one has studied the first section in physics, they can comprehend it. It takes some time to fully grasp the majority of the topics. You can solve numerical problems, such as entropy calculations, more easily if your notions are clear.
Electrochemistry:Important units in electrochemistry include the Nernst equation, its relationship, and its numerous applications, such as electrochemical series, the E.M.F. of galvanic cells, Faraday's laws of electrolysis, electrolytic conductance, and Kohlrausch's law. If you have a solid understanding of the Nernst equation, these units are simple.
Surface Chemistry : This chapter must be carefully read from NCERT Book. In this topic also, fact-based questions can be asked.
You have to practice shortcut formulae for numerical questions so that you can quickly determine the answers and ultimately save time. You should memorize all of the chemical kinetics, electrochemistry, equilibrium, and mole concept formulations. Your numerical technique is strong because you have solved numerous problems in these areas.
Inorganic Chemistry
For this section of chemistry, NCERT is supposedly the key. For the past two to three months, many JEE applicants neglect this section. One should not make this error. The curriculum is extensive, and in order to do well, one must study it from the start and go over it frequently.
Coordination compounds: The main topics of this chapter should include stereoisomers of coordination compounds, Werner Theory, geometry and forms of tetrahedral and octahedral complexes, and crystal field theory and its application.
Metals and minerals: The majority of standard questions come from NCERT. This chapter covers important subjects such as the electrolytic reduction method (aluminum and magnesium), the cyanide process (gold and silver), the carbon reduction method (tin and iron), and the self-reduction method (lead and copper).
Block P: This is easily among the most essential topics in inorganic chemistry. You can easily expect 3-4 questions from this topic.
Organic ChemistryOrganic Chemistry
The interesting thing about IIT JEE Chemistry is organic chemistry. If you understand what's happening, or what is happening behind the scenes of the reactions, you can do extremely well in this section. Never forget that an electrophile is attacked by a nucleophile. Try not to think how a reaction would work out, especially in organic chemistry. Besides that, try to understand the whole process.
You should be aware of the entire mechanisms of the reaction types discussed above. These are by far the largest part of organic chemistry. The most relevant reaction is name reactions and standard reactions. On this subject, direct questions are asked. Every Aldol condensation and Cannizzaro's reaction has a very high probability of obtaining at least one question.
