Preparing Chemistry for IIT JEE
“Setting a goal is not the main thing. It is deciding how you will go about achieving it and staying with that plan.”
When you think of IIT JEE, certainly chemistry would be the soft to crack the nut and excel your rank. But all not without a time-bound, scientific and analysis-based strategy. Nothing is better than that when a student himself analyses the pattern, scope and the subject. However, here we discuss some important aspects of the study of the subject of chemistry to bring to your notice and some guidelines which will help you to connect with JEE. then with the subject.
As the flavor of chemistry is concerned, there is vivid demarcation of physical chemistry, organic chemistry and inorganic chemistry and it is reflected everywhere-study material available, teaching pattern and even in the study pattern. In that case the first thing that strikes is which is the most important?
Truly speaking, in recent years, there has been equal focus on all the three parts. If somewhere you find the analysis in favour of physical or organic or inorganic, that is only because of some interracial questions which cannot be put fairly for one of the part. So, it is not advisable to ignore any part.
Second thing, then. how to do the precise and perfect study of all the three parts?
For precise and perfect study the realisation of level of exam is the most important thing which defines the extent, the student can go, and then a perfect study plan to complete the syllabus, Chapterwise 10-15 yrs’ question paper survey before reading the chapter and an honest effort of solving these questions after the completion of the reading is a worthful measure to buildup a precise realisation of the level. Although it varies chapterwise, for example. Periodic Table is not in IIT JEE syllabus as such but without Periodic Table neither inorganic nor organic and not even physical chemistry can be understood perfectly.
Perfection is not only the concept mastery but it is consolidation also. Perfection roust be measured in terms of good performance. A holistic approach is required for the subject. A simple and independent strategy can help to achieve that in chemistry. Primarily, instead of segregating physical, organic and inorganic one should segregate a group of chapters which are consist of the fundamentals of whole chemistry, which have lots of connection in other chapters and which greatly influence the understanding of other chapters also.
We can include the following chapters here:
1. Periodic Table
2. Chemical Bonding
3. Mole Concept (Wish concentration).
4. Redox Reactions
5. Qualitative Analysis
6. General Organic Chemistry
The consistent periodic revision of these chapters, directly secures minimum 35% of total chemistry marks in all competitive exams. At the same time will act as understanding booster and performance booster/or the remaining topics, this exercise will increase your efficiency to interconnect the linked concepts spread over various chapters.
Apart from that, there is some characteristics of physical chemistry, organic chemistry and inorganic chemistry, if we remain aware of that we can orient the preparation and study programme more efficiently.
Regarding physical chemistry there is one established myth that “physical chemistry is a numerical chemistry” and it has charmful influence on a big section of students. They usually keep a book of numerical in chemistry only in the name of physical chemistry. Even in the class they are waiting for a derivation and formula and finally one chance to solve a numerical to calm down the apetitte of chemistry,
But days are changed now, the recent pattern of 8 years' reflect that IIT JEE doesn't focus on the evaluation of mathematical skills in chemistry. Conceptual clarity, application skills and awareness to the prescribed syllabus have been the main focus. There was one question on significant numbers in 2009. It has been the most ignorant comer of the syllabus. So, the purpose of this question can be said to check the awareness and application of significant figures.
Now-a-days multistep questions are not asked but questions are very conceptual. Even incorrect options are based on misconceptions and miscalculations only. To have better command over physical chemistry the following measures can be worthful :
Ř Maintain one analysis book especially for physical chemistry.
Ř On the completion of every chapter, note down the ceptually weak topics.
Ř List out the formulas you derived, and learnt in the chapter.
Ř On the completion of a topic, you solve practice problems from many of the available books.
Ř Note down the Q. no. and source of all the challenging problems, where you committed mistakes.
Ř Must write minimum two tests for every chapter.
Ř Solve previous years' IIT JEE Q. papers. Tick out those questions that you find connected with other chapters also.
A right aptitude in physics and mathematics naturally excels your performance in physical chemistry but organic and inorganic chemistry have their own independent streams of understanding. A careful and patient approach is required to connect with organic chemistry.
‘Nomenclature' and ‘Isomerism’ are the two basic chapters that help you to enter into the organic chemistry, so it is very important to make them thorough. These days 'isomerism' especially the 'stereoisomerism' has become very important. We can say that the best questions of chemistry in IIT JEE have been from ‘stereochemistry’ only. An extensive approach is really required here. ‘General organic chemistry’ is the most important in all respects of facts, concepts and applications. Most of the questions asked in IIT JEE can be attributed to ‘General organic chemistry’ only, A strong conceptual hold and regular practice can make one fine-tuned with this part.
Once ‘GOC’ becomes perfect, then remaining functional compounds would not be difficult to handle.
However, there are many reactions with varied mechanisms and rearrangements, which cannot be generalised but the following measures can help to ease them out :
Ř Most important-don’t read only Read and write.
Ř List out the reactions chapterwise. Use pencil, erase and write the product at regular intervals.
Ř Revise the reactions, recalling the mechanism. Recall! intermediates, stereochemistry, rate determining step and by products also.
Ř Practice daily some of the ‘Conversions’, writing reagents and products in detail.
Ř Focus on subjective working, objectivity will come itself with greater perfection.
Ř In organic chemistry interconnectivity of chapters is characteristically more prevailing, so chapterwise IIT JEE questions can be solved only when one is well through in general organic chemistry.
Inorganic chemistry is an extensive part of chemistry. Usually, students don't gel interested deeply into the subject, and rely more on mugging-up of facts. But a good understanding of Periodic Table, chemical bonding, redox reactions, equilibrium and electrochemistry could make the inorganic chemistry quite enjoying. Contrary to general perception, we find that in inorganic chemistry most of the questions which are asked are really conceptual, concerned with structures, processes and applications. Students unnecessarily waste their time in mugging up of hundreds of reactions, that also with stoichiometric coefficients. It’s simply over-sincererity. It is also incorrect to say that you don't require to learn or to mug up but there is rational limit and scientific way of doing that. Two rounds of practicals prescribed in board exams will help a lot for a realistic approach to inorganic chemistry.
In recent years, the significance of coordination chemistry has increased. A vast approach towards analytical chemistry is shrinking over the years. Usually, straight questions are asked now-a-days in analytical chemistry. Metallurgy, transition elements and most wide representative elements are still significant. Although subject is so vast but simply following measures can increase your efficiency and performance.
Ř Prepare summary notes for representative elements and transition elements,
Ř Prepare yourself important charts and tables in metallurgy and qualitative analysis. Paste that near your study table. Daily twice or thrice, even a casual look at that can keep you updated.
The high spirit, positive mind and hard labour turn everything favourable. The extract of this discussion could help you to analyse your preparation. One thing which is the most important is that, the syllabus must be completed by the end of October. An extensive three months’ revision should be planned which could include some rectification of some concepts and all. One practice book should be completed in first reading and another practice book in revision. A time-bound revision would certainly take you near to the success.
It has been truly said: “Thinking well is wise, planning well, wiser; but doing well is the wisest and best of all.”
