THE ART OF PREPARING FOR JEE
IIT-JEE exam is based on concepts and more important is their applications. It is observed from last
few years that instead of asking lengthy questions with tedious calculations, short questions with
easiercalculations are being asked; which are more conceptual.
_ Whatever is the level of preparation, doubt will always arise in your preparation strategy
_ You may feel that the time left out is very less
_ Your mind may go blank sometimes
_ You always in need of a support.
_ You may tend to think of the past
_ Your success just not comes with your effort and practice, your mind set on the day makes a big
_ The IIT-JEE is not only a test of a student’s preparation but also how well he can handle the
_ So tune up your mind with positive thoughts.
_ Avoid friends who have negative mind set.
_ Take a real JEE experience in your practice tests.
_ Don’t compare yourself with others.
_ Don’t get carried away by what others say
On analysing last few years results it was observed that chemistry is always the deciding subject for
better rank and one has to put little more efforts in the subject. Here we will look at the best
mannerin which chemistry can be revised. Analysis of previous papers of IIT-JEE, it is quite clear
thatchemistry is scoring subject in terms of time invested and marks obtained.
The entire syllabus of chemistry is divided into three major units, namely physical &
generalchemistry, inorganic and organic chemistry. All these are equally important.
Let us have a glance of the syllabus in the order of priority.
This part of chemistry is generally given more weightage. Physical chemistry chapters are not
theoretical and memory based rather they are more conceptual and problem based. It is advisable
tofollow the given order of priority and emphasize on the topics mentioned in each chapter during
Electrochemistry: Application of Nernst equation, batteries, relation between thermodynamic
quantities& EMF and application of Kohlrausch law.
Ionic equilibrium: Solubility Product and factors influencing solubility of a sparingly soluble salt,
hydrolysis of salts, buffer, indicator theory, and simultaneous equiliria based problems
Chemical kinetics: First order equation with its application, graph related problems and
temperatureeffect on rates of reactions.
Colligative properties: Mostly formula based problems will be asked on CP. Don’t forget to have a
look in to Von’t Hoff factor.
Gaseous and solid state: Behavior of real gases, Vander waals equation, diffusion, Unit cell
parameters (such as edge length in terms of radius, packing fraction, CN, density and types of
voids),structure of ionic crystals and defects
Chemical bonding: Questions on chemical bonding find a place every year. It is absolutely
necessary to prepare a table containing essential data to be used as a ready reckoner and a quick
glance. Problems related with bond angles, dipole moment, geometries, molecular orbital theory
andbond order calculation are needed to be revised.
Thermo chemistry and thermodynamics: entropy calculation and free energy calculation, Hess'
law applications, resonance energy calculation.
Revise all the formulae of physical chemistry, with their applications and short cut methods. It will
help you to score faster in formula based questions. It is more advisable that now solve multi
conceptual problems. Also do not limit up your practice to only selected chapters, better solve
miscellaneous type exercises which give exact simulation of examination.
This part also takes good weightage in chemistry paper. It is more conceptual and completely
theoretical hence more attention has to be paid on this topic.
Questions are more frequently asked from the following topics.
_ Acid- base strengths and reaction intermediates
_ Geometrical and optical isomerism
_ Elimination reactions and Electrophilic addition reactions
_ Electrophilic substitution reactions
_ All named reactions from carbonyl compounds
_ Phenols and diazonium salts
_ Very basic information about Carbohydrates, amino acids and polymers
Try to confine to the topics and named reactions given in syllabus. This is not the time to read all
theinformation given in text books.
Mechanism of all the named reactions included in syllabus must be known thoroughly. Practice
moreproblems based on chemical equations and problems involving identification of unknown
compounds. Every year problems based upon identifying the compounds were asked.
The weightage of inorganic is increased in the last two years papers and we cannot ignore this
section. The main chapters/topics which one should emphasize are
Coordination compounds: Geometrical isomerism, IUPAC nomenclature, VBT to predict the
structure of coordination compounds as well as their magnetic behavior
Metallurgy: Make simple memory grids on ores and extraction procedures. This won’t take more
than an hour to go through.
Chemistry of non-metals: This is one of the most important areas where from 2 to 3 questions were
asked in previous exams.
Try to concentrate on Occurrence and isolation of B, Si, N, P, S. Properties and structure of hydrides,
halides, oxides and oxyacids.
Qualitative analysis: Confine to the analysis of ions given in syllabus. Try to list down as many
reactions as possible for these ions, which indirectly enhance your strength in chemistry of
Chemistry of metals: Finally you can have a look into the properties of Oxides, Hydroxides,
Halides, Carbonates, Bicarbonates and sulphates of alkali and alkaline earth metals.
The pattern of the IIT JEE paper has seen a major change in the last few years. The same subject
with full coverage of the syllabus has to be answered in both the sessions of the examination on the
The aim of a student is not to answer all the questions. An average student can aim at attempting
60% questions with 90% accuracy, and then a reasonably good rank is assured.
Passages for comprehension-based questions are generally not adequate to give all the
information needed to answer the questions that follow. Matrix matching type questions need
particular attention as either you score full marks or you end up with a naught.
All the Best
