CBSE Chemistry- Preparation and Revision

Hey Friends.

This article addresses the preparation and revision for the Chemistry paper.

Note: Apart from the tips given below, you need to rely on memorizing. The key to memorizing is identifying patterns, using mnemonics and multiple revisions (preferably writing and not just reading).

INORGANIC          

 (p, d and f block, coordination compounds)

Main question types:

(not an exhaustive list):

1. Direct questions

2. Equations

3. Story Questions (Compound A + B will give C. C when heated will give D and so on)

4. Give reasons

5. Structures

SUGGESTIONS:

1. Give reasons

2. NCERT is not sufficient.

3. Try to explain/give reasons for all lines given in the textbook

4. Refer to past year papers and question banks

5. To remember a series of structures such as oxoacids of sulphur, oxoacids of phosphorus: Try to identify a pattern. Once you know the pattern, you can easily construct all the structures and don’t have to remember all of them.

6. Can prepare revision/ note sheets for each element containing its preparation, chemical properties, physical properties, and structures. It will be easier for you to read and revise these as they will be structured, handy and have been prepared by you.

7. For redox reactions, you can remember the individual half equations and add them up to obtain the final equation (while balancing the molecules and electrons). This is easier as the half equations are common to several reactions. (Refer to Pradeep for a list of half equations. You will have to distinguish between those in the syllabus and extra ones.)

PHYSICAL

(Solid state, Solutions, Electrochemistry, Kinetics, Surface chemistry, Metallurgy)

This topic does not require a lot of discussion. However:

1. For metallurgy, yes, you need to remember everything relevant.

2. Solid state and examples are very important.

3. Graphs are important in kinetics and surface chemistry.

4. In all these chapters, remember the mathematical formulas and keep them ready for use. Though some of them are easily and intuitively derivable, don’t waste time figuring out the formulas during the exam.

MISCELLANEOUS

 (Biomolecules, Polymers, Chemistry In Everyday Life)

Misconception: Students generally pay less attention to these chapters as they are relatively simple and easy to understand. These chapters also have a decent weightage in the board papers and are hard to answer with only knowledge of the rest of the syllabus. Do prepare well.

BIOMOLECULES

1. This chapter can be understood and learned.

2. Don’t miss out on differentiate questions and examples.

3. Don’t miss out on the structures. If you are a visual learner, learn the whole structure. If not, remember the monomer units, the condensed formula and the connecting carbon atoms.

POLYMERS

TABLE TO SUMMARISE POLYMERS

Table to summarize Polymers:

Preparing a table like this, with all the polymers (and the name, structures, uses, and properties) is very useful and handy way to learn and remember this chapter.

CHEMISTRY IN EVERYDAY LIFE

1. No way out of this chapter. You need to rote learn it.

2. Generally, a value based question comes from this chapter. (See past year board papers)

I used a diagram like the one given below to help me out:

SUMMARY FOR THE LAST CHAPTER

CLOSING NOTE

I used to stick papers filled with tables, flowcharts, and equations on my walls related to chemistry so that I could repeatedly see them and remember the equations.

On the days before the exam, you have to revise everything for chemistry, even if you think you know the topics.

You can score extremely well in this paper.

All the very best.
