Chemistry is a scoring subject and students can obtain higher marks in this subject by putting in little hard work. Chemistry is a very important subject for both board exam and various competitive exams. One can score 95+ marks in this subject in board exam by investing little bit of time. Nowadays different competitive exams are conducted within one month after the completion of class 12 board exam. If you have command over this subject then you can really perform well in different competitive exams too.
Why students face difficulty in chemistry?
Many students fail to score good marks in this subject. The only reason behind it is that they fear from chemistry. If you really want to perform better in this subject then try to remove chemistry-phobia from your mind. Believe me, chemistry is one of the most easy subjects in the science stream provided you study this subject with full concentration and consistently. You must read chemistry regularly or you will fail to prepare it well for the board exam. Try to consult your teacher and friends when you find any topic difficult to understand.
How to prepare different chapters of chemistry for class 12 board exam?
Chemistry is divided into Physical chemistry, Inorganic chemistry and Organic chemistry. While preparing Physical Chemistry you must learn all formulas of Solid state, Solution, Electrochemistry and Chemical Kinetics. Try to solve at least five numerical daily from these chapters. You should also learn theory of these chapters as it is important for both board and competitive exams.
Inorganic Chemistry requires lots of learning. It is wise to prepare a note of Inorganic chemistry as in this you need to learn lots of chemical reactions, processes and preparation of different chemical compounds. Questions are directly asked from this portion. It is a very important portion of chemistry for engineering and medical exams too. So never underestimate Inorganic chemistry.
Organic Chemistry is probably the most easiest portion of chemistry in class 12. You can secure good marks in this with little efforts. Solve all problems of NCERT exercise to have command over this portion. Alcohols, Phenols and Ethers and Aldehydes, Ketones and Carboxylic Acids are the two most important chapters from Organic chemistry.
Some important topics from Organic chemistry are- Sandmeyer’s reaction, Nucleophilic substitution reaction, Optical isomerism, Electrophilic substitution reaction, Esterification, Reimer-Tiemann reaction, Kolbe’s reaction, Williamson synthesis, Rosenmud reduction, Gatterman-Koch reaction, Nucleophilic addition reaction, Clemmensen reduction, Wolff-Kishner reduction, Aldol reaction, Haloform reaction, Cross aldol condensation, Cannizzaro reaction, Hell-Volhard Zelinsky reaction, Carbylamine reaction and Coupling reaction.
Important chapters for class 12 board exam
If you want to secure 95+ marks then you need to concentrate equally on all chapters of chemistry. For weak students who want to get magical 23 marks i.e. passing marks or more, it’s important that they prepare selective but important topics. First of all thoroughly learn last three chapters of chemistry Biomolecules, Polymers and Chemistry in Everyday Life. These three chapters together carry 10 marks. Prepare all above mentioned topics of Organic chemistry.
“p-Block Elements” alone carries 8 marks and you must prepare this chapter very well. Coordination Compound should also be prepared very well as it is a very important chapter for CBSE or ICSE board and different competitive exams. Surface Chemistry is another chapter that you must prepare well. Often 3-4 questions from this chapter are asked in competitive exams. Strong command over Physical chemistry is helpful in securing high marks in chemistry.
Important chemistry books for class 12 board exam
NCERT is the most important book for the class 12 board exam. Almost all questions in board exam are asked from NCERT book. Even for the competitive exams, NCERT is very important. You can buy sample papers for solving different types of questions. Side books can help you in understanding different topics very well.
