If someone asks you what chemistry is, you should be able to explain it to them. Simply said, chemistry is the discipline of science that studies the composition, structure, and characteristics of matter. Chemistry affects practically every aspect of our lives. From the toothpaste, we use to brush our teeth to the vegetable oil we use to cook our food, and even the medicines we take to battle diseases, everything is chemical and has its chemistry.
Chemistry is the study of atoms and molecules in general. Chemistry underpins almost every discipline of science. Biochemistry is formed when chemistry is combined with biology, and physical chemistry is formed when chemistry is combined with physics. To put it another way, we can’t perform anything in applied science without using chemicals, and hence chemistry. Chemistry is one of those subjects that, if thoroughly prepared, may secure you a spot in IIT JEE. The majority of chemical topics are not overly complicated and are assessed directly.
The desire to unravel the complexities of JEE is fueled by a desire to pursue a dream career. Chemistry is the most significant topic in the exam, yet it is also the simplest of the three. Candidates should not avoid or overlook the topic because it is the only surefire route to get good grades and a spot in one of the prestigious Engineering institutes. So, take care with it!
In IIT JEE 2021, chemistry is one of the scoring courses. Physical chemistry, inorganic chemistry, and organic chemistry are the three sections of chemistry. Topics such as s, p, and d blocks, transition elements, surface chemistry, coordination compounds, gaseous state, nuclear chemistry, chemical equilibrium, and stereochemistry are often overlooked by students. These themes are not only simple, but they also appear in IIT JEE Chemistry examinations every year, making them high-scoring, but students ignore them. You can check IIT JEE Chemistry Study Notes in order to download some revision material to help you with your preparation.
Taking notes is usually beneficial in JEE preparation. You may not recognize its significance now, but you will in the next month when you have a large amount of material to revise or when you need to review a forgotten subject and can’t find the relevant book. Always take notes in the language with which you are most familiar. Never try to reproduce the book’s precise text. Read them out loud, then write them down in your own words.
If you’ve enrolled in a coaching program or even if you’re in an ordinary school, pay attention in class because teachers frequently utilize amusing examples, quotes, or other unusual lines when explaining a concept (you may include them in your notes). The entire picture of that lesson and notion would come in your head whenever you recall such lines or examples. Any thought associated with that amusing or unusual example will stay with you for the rest of your life.
When taking notes, experiment with different colours of ink. You have the option of selecting colours that match your preferences (like Important, Very Important, Usually asked, etc.). This will assist you in completing your revisions quickly. You must not only write notes but also revise them every two weeks. This way, you won’t forget anything and won’t be under strain in the final month of revision. Make your tricks and shortcuts. These, believe me, will come in handy throughout the exam.
Instead of using notebooks, make your notes on A4 paper. They should be filed together. Keep a page in your pocket whenever you go out (to the market, for example) and take a quick look. This habit may appear odd at first, but it will benefit you in the long run. Finally, but certainly not least, keep track of your errors in a notebook. Make a note in this notebook whenever you make a mistake in a mock test or forget a concept or formula. With time, you’ll amass a collection of exam blunders that you’re not supposed to make. Regularly revise this copy. This would help you get a better grade.
As always, begin by choosing questions from topics in which you are well-versed and confident in your ability to solve them. Starting by answering these questions will give you confidence. After you’ve answered these questions, you can continue to the numerical puzzles. Chemical Thermodynamics, Mole Concept, Solid State & Atomic Structure are the most common sources of numerical issues. In most cases, the paper will ask a question based on Molecular Orbital Theory. All of these problems are straightforward to solve if you understand the concept and formulas. You can solve these problems rapidly if you know the proper formula and notion.
Organic science questions are significantly more difficult, therefore unless you have a strong grasp of organic chemistry, you should solve it after you finish the inorganic and physical chemistry questions.
Physical chemistry is a science that deals with supermolecules. The behaviour and structure of a chemical compound are studied in this discipline of chemistry. It describes how the compounds interact with other substances at the molecular and atomic levels. Physics concepts such as motion, energy, force, time, and thermodynamics are applied in physical chemistry. NCERT textbooks for Class 11 and 12, Bahadur, P. Tandon, Narendra Avasthi Balaji Publication, Organic Chemistry, and others are important books for JEE Physical Chemistry preparation.
Organic chemistry is the branch of science that studies the structure, characteristics, composition, and synthesis of organic molecules (compounds with carbon). It is very hard for students, and they typically avoid it. You will like it once you have gone over the JEE syllabus for Organic Chemistry and done an in-depth examination of the difficulty level of the topics. Organic chemistry is responsible for the petroleum products we use daily. Solomons, NCERT Textbooks, Himanshu Pandey, OP Tandon, and other important books for JEE Organic Chemistry preparation are listed below.
Thousands of non-organic and organometallic substances are studied in inorganic chemistry. Inorganic compounds are those that do not have carbon-hydrogen bonds in them. An example of an inorganic chemical compound is a common salt. It is a branch of physics concerned with the study of matter. NCERT textbooks, P. Tandon’s Concise Inorganic Chemistry, J.D. Lee’s Problems in Inorganic Chemistry for JEE Main & Advanced, V. K. JAISWAL’s Problems in Inorganic Chemistry for JEE Main & Advanced, and others are important books for JEE Inorganic Chemistry preparation.
In January 2020, there are 9 questions from Physical Chemistry, however, in September, there are 10 questions from Physical Chemistry. Solving previous 10 year IIT JEE Chemistry papers is usually a good idea. The majority of the questions are asked in a roundabout way. This is more true for inorganic and organic chemistry than for physical chemistry because physical chemistry involves a lot of concept testing. When you tackle problems from previous years’ IIT JEE Chemistry tests, you’ll see a pattern in the kind of questions and concepts tested. In fact, with careful planning, chemistry can be the highest-scoring of the three subjects in IIT JEE.
