How To Score 80% And Above In CBSE Class 12 Chemistry?

CBSE board exams are very important in a student’s academic life as it paves a path for the future studies and entry to good higher education institutions. The students are often faced with doubts as to how to prepare for the boards that ensure they score well. Often popular advice tells them that it’s tough to score well in the boards, therefore students many times go for multiple reference books and materials to find the perfect study material so that they don’t miss out on any aspect of the syllabus and can achieve high marks. However, scoring well in CBSE boards is not that tough. All you need is a good strategy for completion of the syllabus and ample time for revision. In this article, you can find how you can prepare a strategy for scoring 80% and more in CBSE Class 12 Chemistry. You can find practical tips and tricks that will ensure you cover the syllabus on time and go confident for the exam.

Syllabus of Class 12 CBSE Chemistry

The prescribed study resources for the CBSE exams are the NCERT books. They are designed to teach the students the fundamentals and how to apply them to different problems. While preparing for the board exams students must first go through the entire syllabus. Also, the marks weightage for each chapter should be considered so they can adopt a strategy and focus on chapters that can gain them more marks. 

Although marks are important from the exam point of view, reading the NCERT thoroughly will help students in making their subject foundation strong, which will help them answer any indirect questions that may be asked in other competitive exams. It will also help them in their future study courses if they pursue their higher education in the subject.

The entire syllabus comprises 16 chapters, which are divided into two books- Part 1 and Part 2. Part 1 consists of 9 chapters. Part 1 mainly covers the inorganic and physical chemistry chapters. Chapters 1-5 of Part 1 cover the physical chemistry units and hold 23 marks of weightage in total. Chapters 6-9 of Part 1 cover the inorganic chemistry units and hold 19 marks weightage. Part 2 of the book contains chapters 10-16, which cover the organic chemistry units. This part holds 28 marks of total weightage.

Let’s see the detailed chapter-wise syllabus of Chemistry Part 1 and the important topics which students should focus on first-

Chapter 1- The Solid State

Students will also learn the different colligative properties and their deviations from normal behaviour. There are 12 intext questions along with 41 exercise questions. 

Chapter 3- Electrochemistry

This chapter deals with the study of electricity that is produced when spontaneous chemical reactions take place and its use in bringing non-spontaneous chemical transformations. Students will learn about different types of cells. There are a lot of numerical-based questions from this chapter that students should practice from the topics like Nernst equations, Gibbs energy, electrolytic and electronic conductivity, Kohlrausch law, etc. They will also learn the process of corrosion as an electrochemical process. There are a total of 15 intext questions and 18 exercise questions.

Chapter 4- Chemical Kinetics

This chapter has mainly numerical-based questions and therefore students should practice the exercise questions thoroughly from this chapter. This chapter is also important from a competitive exam point of view. Students will learn about the concepts like average and instantaneous rate of reaction, rate constant, order of reaction, etc. It has a total of 9 intext questions and 30 exercise questions which are mostly numerical.

Chapter 5- Surface chemistry

In this chapter, students will be introduced to chemical reactions that occur at the interfaces. Important concepts like adsorption and its different types will be covered here. An important topic here is enzymes and catalysis. Another important concept is the colloids and their different properties and types. There are 8 intext questions and 27 exercise questions in this chapter.

Chapter 6- General principles and processes of isolation of elements

This chapter describes the metallurgical processes and the extraction of metals since ancient times. Students will learn important terms like minerals, ores, calcination, roasting, refining, etc. Important topics here are the oxidation and reduction involved in extraction procedures and the different processes of refining metals. There are 4 intext and 27 exercise questions in this chapter.

Chapter 7- The p-block elements

This chapter describes the general trends seen in groups 15-18 of the periodic table. Students need to focus on the topics like the preparation, properties and uses of some of the most important elements from these groups like Nitrogen, Oxygen, Sulphur. Also important are the halogens, noble gases, and their properties. There are 34 intext questions and 40 exercise questions in this chapter. Students should focus on understanding the structures of different elements and the important reaction equations from this chapter.

Chapter 8- The d and f  block elements

Also important are their electronic configurations. Elements of these blocks form some of the very important compounds and students should thoroughly practice these reaction equations. There are 10 intext and 38 exercise questions in the chapter.

Chapter 9- Coordination compounds

This chapter introduces coordination compounds and the rules of their nomenclature. Important terms here are the coordination entity, ligand, coordination sphere, oxidation number, etc. Students will also learn the isomers in coordination compounds and the different types of bonding in these compounds. They should thoroughly practice the structure of these compounds. There are10 intext and 32 exercise questions.

Part 2 of the book covers the organic chemistry chapters-

Chapter 10- Haloalkanes and Haloarenes

Students are introduced to the halogenated compounds and their IUPAC nomenclature.
