Chemistry For IIT JEE : Chemistry is the most scoring subject among PCM, in which JEE aspiring students can get 100% if their foundation in the concepts is strong. Most of the questions are comparatively easier in the Chemistry section than the other subjects in IIT JEE.The different parts of chemistry have a slightly different approach which is to be followed. In the case of organic chemistry practising the chemical equations, reactions and mechanism will help you out. For physical chemistry, you need good conceptual knowledge and regular practice. In the case of organic chemistry, you need to be good at memorizing. Learning and practising the way out for this section. In this article, we will provide you all the information regarding how to prepare Chemistry for IIT JEE Exam .How to Prepare Chemistry for IIT JEE | Important StepsIf scoring higher is your goal, follow the following steps to ensure that you leave no stone unturned in your endeavour to crack IIT JEE Chemistry:Focus on all 3 parts – Organic, Inorganic and Physical Chemistry.Periodic Table is a must-to-know.Understand complete reaction mechanism.Learn formulas thoroughly.Give extra attention to d- block elements, f-block elements and co-ordination compounds.Make personal notesStep 1: Focus on all 3 Parts – Organic, Inorganic and Physical ChemistryAlways remember, all three parts of chemistry are interconnected; you can’t ignore any part. You should have strong hold on each part if you want to score good marks in this subject.Start with Physical Chemistry before moving on to Inorganic and Organic Section.Step 2: Periodic Table is a Must-to-KnowIf you are just starting to study Chemistry, I would suggest you post a large-sized poster of the Periodic Table in your study room.Step 3: Understand Complete Reaction MechanismDon’t ever try to remember any reaction; that is not a good practice. Try to understand complete mechanism behind each and every reaction. Especially for Organic Chemistry, it is very important to completely understand mechanism of reactions.Step 4: Learn Formulae ThoroughlyYou must memories formula of Chemical Bonding, Equilibrium, Kinetics, and Radioactivity.Step 5: Give Extra Attention to D- Block Elements, F-Block Elements and Co-Ordination CompoundsMost of the questions that come from p and s block elements are easy to solve. I will suggest you to pay extra attention to co-ordination compounds and d-block elements. For more information,This is not important only for Chemistry but for all subjects if you are seriously preparing for JEE examination.You are now aware of how to prepare for chemistry for IIT JEE. Gear up your preparation and develop the habit of regular revision. Take JEE mock Tests and go through the test analysis to know your weaknesses. Work on your weaknesses and improve your score. As and when you keep preparing each chapter, take chapter-wise JEE Practice Tests to strengthen your basics.We hope this article on IIT JEE Chemistry preparation helps you. if you have any questions please post it in the comment box below.

Let’s get to the main stuff! – THE IMPORTANT TOPICS (SUBJECTWISE)Important topics for Physics in JEE Main 2018The physics portion for JEE has 20 chapters, all in all, that has to be covered over 2 years’ time. They are Dimensional Analysis – Although a very easy chapter but knowing correct units and dimensions for physical quantities can easily help you eliminate options in multiple choice type of questions, Gravitation & Electrostatics, Current Electricity & Heat Transfer – again these are conceptually similar to each other, Electromagnetic Induction, Waves & Sound, Geometrical Optics, Thermodynamics, Kinetic Theory of Gases, Rotational Dynamics.Question Pattern followed in PhysicsCurrent Electricity: 8 questions asked in the actual JEE paper each year on an averageElectrostatics: 4 questionsOptics: 3 questionsHeat and Thermodynamics: 2 questionsLaw of Motion: 2 questionsWaves: 2 questionsSimple Harmonic Motion: 2 questionsTips to score well in PhysicsNote down the formulae and results, it will help during revision. Practice as many questions as you can, keeping in mind the availability of time. Avoid lengthy and complicated problems at the last minute, if time is limited!Focus on your strong areas.Important topics for Mathematics in JEE Main 2018Important topics for Mathematics include 3-D Geometry – Weightage: 5% Questions from this topic are generally straightforward so you can solve them easily by reading the questions properly.Probability and Statistics – Weightage: 7%, Vector Algebra – Weightage: 5%, Integration – Weightage: 8% (Definite + Indefinite integration), Complex Numbers – Weightage: 5%, Parabola – Weightage: 3%, Trigonometric Ratios – Weightage: 3%Question Pattern followed in MathematicsCoordinate Geometry – 7 QuestionsContinuity/ Differentiability, Limits – 3 QuestionsComplex No., Quadratic Equation – 3 Questions eachIntegral Calculus – 3 QuestionsSequence and Series – 2 QuestionsTrigonometry – 2 QuestionsTips to score well in MathematicsConceptual understanding is preferred. There is no alternative to Practice, Practice a lot!Important topics for Chemistry in JEE Main 2018Chemical bonding & the periodic table – This is by far the most fundamental and the most important topic in Chemistry. If you can master Chemical Bonding and the properties of periodic table elements, then Chemistry will be an easy subject for you over many years to come.Other topics include Carbonyl Compounds & their derivatives, Redox reactions, Mole Concept & the concept of equivalents, Solid state, solutions & gases theory, Thermochemistry & the Second Law of Thermodynamics (Remember, we told you about this in the Physics section).Question Pattern followed in ChemistryTransition Element and Coordination Chemistry – 3 questionsPeriodic Table and Representative Elements – 3 questionsGaseous State – 2 questionsAtomic structure – 2 questionsAmines – 2 questionsSolution and Colligative Properties – 2 questionsGeneral Organic Chemistry – 2 questionsCarboxylic Acids and Derivatives – 1 questionHydrocarbons – 1 questionCarbohydrate, Amino Acids, and Polymer – 1 questionTips to score well in ChemistryChemistry is amongst the tough subjects as it involves cramming of formulae and reactions. Thus, understand the conceptual base of the topics. Also, remember! The Periodic table is the most scoring part.Final Tips (Must follow to prepare efficiently)Make a proper study time-table and follow JEE Main 2018 syllabus very carefully.To score well in the examination, students are advised to prepare PCM subjects taught in 11 and 12 in their schools.Practice mock tests to know your weak areas. Time Management is very important. Set and stick to a timetable so that you can easily decide and divide study hours. Divide your time well among school, tuition, coaching classes, exercise, entertainment, etc.Finally, don’t take life too seriously, do not take the stress and keep yourself healthy. You must create violent plans and execute with much will, this would lead to success not just here, but in LIFE!!Hope it helps!!
