JEE 2013 Preparation – Week 6

Following is the plan for this week :

MATHEMATICS :

From the same book – Eduwiser’s Vectors and 3-D Geometry by Prof. K. C. Sinha, work on chapters - Introduction to Three Dimensional Geometry, Angle Between Two Lines, Straight Lines and Plane before working on the Straight Objective Type Questions from Competition Section of Vectors portion. The strategy here will almost be the same as that for the Vectors section – go through the theory portion of all the chapters and the worked out examples. From the exercises, solve a couple of questions of each type. There is no need to solve each and every question from the exercises. What you should do while solving questions here, is trying to solve the same questions by Vector method as well. Almost every question in Three Dimensional Coordinate Geometry can be solved using Vector method and vice versa, so keep that in mind.

After you are done with the above, switch to the Competition Section of 3-D Geometry. Solve all the worked out examples, including the “Prove that” ones. However, from the exercise of Subjective Type Questions, you can skip “Prove that” questions. Also solve all the new pattern questions (including the Straight Objective Type Questions) from the same book.

Once you are done with the above, you should finish the Straight Objective Type Questions of Vectors section. Now, when you are solving questions here, try to solve it using 3-D Geometry method too. Very often, the solution in 3-D Geometry method will be a lot simpler and easier to work upon. This is majorly because 3-D Geometry has tremendous similarities with 2-D Coordinate Geometry that we have already worked on. You have to be thorough with Vectors and 3-D Geometry because these topics are very easy and the questions asked from these topics are fairly simple and scoring. I have come across numerous IIT aspirants who have ignored Vectors and 3-D Geometry and have regretted it later.

All the above should take about thirty hours of time.

CHEMISTRY :

This week’s target in Physical Chemistry will be Chemical Equilibrium. This chapter is one of the medium difficulty ones in Physical Chemistry and can help you score with slight effort. The topics that you should concentrate on under Chemical Equilibrium are – Law of mass action, Equilibrium constant, Le Chatelier’s Principle (effect of concentration, temperature and pressure); Significance of DG, DGo in Chemical Equilibrium, Solubility Product, common ion effect, pH and buffer solutions; Acids and bases (Bronsted and Lewis concepts); Hydrolysis of salts.

Cover these topics from Dr. P. Bahadur’s book as well as Dr. R. C. Mukherjee’s book. Solve only the worked out examples from Dr. Bahadur’s book whereas solve each question from the worked out examples and exercise of Dr. R. C. Mukherjee’s book. Also practice new pattern questions of the above topics from Coaching Classes Course material. All doubts from the above topics should be cleared at once with help from your teachers.

All of this should take not more than fifteen hours.

For Organic Chemistry, we will finish off Preparation, properties and reactions of alkenes and alkynes – Physical properties (boiling points, density, dipole moments), Acidity of alkynes; Acid catalyzed hydration of alkenes and alkynes (exclude stereochemistry of addition and elimination); Reactions of alkenes with KMnO4 and ozone; Reduction of alkenes and alkynes, Preparation by elimination reactions; Electrophilic addition reactions of alkenes with X2, HX, HOX and H2O (X = halogen); Addition reactions of alkynes and Metal acetylides, from your Coaching Classes course material/Organic Chemistry by Prof. S. Lal. You should also refer the book on Organic Chemistry by Morrison and Boyd in case you do not understand any of the topics mentioned above.

This should take five hours of your time.

In Inorganic Chemistry this week, you should finish Ores and minerals of iron, copper, tin, lead, magnesium, aluminium, zinc and silver from your Coaching Classes course material or NCERT books. This should take another five hours of your time.

PHYSICS :

In Physics, we will cover the chapter on Gauss’ Law and its application as well as the chapter on Capacitance from Dr. H. C. Verma’s Concepts of Physics – Vol. 2. Both the chapters are simple. In fact, the chapter on Capacitance is very similar to the chapter on Current Electricity. Try to draw parallels between the two chapters and you will notice that the same principles are used on solving questions from both the chapters.

Pay special attention to the chapter – Capacitance. The base has to be very strong and you should practice hard to make it so. Get your doubts from Gauss’ Law resolved at once but do not do this for Capacitance. Try solving the questions yourself. Keep in mind the steps you follow for different types of questions and stick to them.   

Also try solving new pattern questions from your Coaching Classes material. This week, Physics should take up about fifteen hours of your time.

(Some students have written back to me personally saying that they have not joined any Coaching Classes and hence do not have access to their material. In this case, you can either borrow it from your seniors who have already taken admission in some college, or from your friends. If neither works, you can enroll for the correspondence material from FIITJEE, Akash or Prof. K. C. Sinha Classes.)

Until next week, all the best !
