FAQs on CBSE Chemistry Class 12 Syllabus 2024-25

1. How to prepare for the board exam with the help of the Chemistry Class 12 Syllabus?

It is important for aspiring Class 12 students to know the CBSE Syllabus of Class 12 Chemistry. The syllabus paves a way to get an idea of the types of questions from beforehand. Only from a proper syllabus we can know the actual weightage of a particular topic and chapter. It makes it easy for the students to decide how to proceed and study which topic to score more marks. It is extremely important to know the Chemistry Class 12 Syllabus from before since studying the three main sections: Physical, organic and inorganic chemistry need separate approaches. Inorganic chemistry which mainly has to be memorized should be kept in the regular study plan. On the other hand, Organic chemistry which is mainly conceptual needs regular practice. Numerical problems of Physical chemistry also need to be practiced regularly so a study plan should be prepared in such a way that all these sections are touched on a regular basis.

2. What are the tips to prepare well for CBSE 12th board exams 2024-25?

Students got confused when they came to know that board examinations are about to come. They take a lot of pressure in which their study and health suffer. Here, we are telling you how students can prepare effectively for the exams to gain good marks.

  • First of all, collect all required study material such as a subject related book, notes, Vedantu sample papers, etc.

  • Now, analyze every topic with the Vedantu syllabus to know which topics you have to cover in a proper manner.

  • Set a time limit for every topic and take a break after every half an hour.  It will keep your mind fresh and keep your body active. Set a time limit of 3 hours and solve a Vedantu mock test paper.

  • Revision is critical to remember every topic. Therefore, don’t forget to revise every topic.

3. Instead of the Syllabus of Chemistry Class 12 CBSE, what other things Vedantu provides for Class 12 Chemistry?

Vedantu has provided the updated syllabus for the Class 12 syllabus. Other than that Vedantu provides continuous online support and assistance to the students who need help. Vedantu provides NCERT Chemistry solutions, solutions of previous year question papers, sample papers with solutions for practice. Vedantu subject experts have in fact created a whole handy library for the students to enrich their knowledge and concept in chemistry. Vedantu provides customized one-to-one tuitions for Class 12 students to clear their doubts in Chemistry and strengthen their basic concepts of chemistry in a clear and concise manner.

The experts have created such study materials that can reduce extra stress and effort of the students, saving both time and memory. This helps the students to secure more marks than average. Vedantu also provides free revision notes which they can study without visiting a coaching class. This saves their precious time and money.

4. What are the future prospects of chemistry for Class 12 students?

Chemistry is broadly but indistinctively divided into physical, inorganic and organic counterparts. Although these counterparts have a lot in common, career options are unique for each one of them. Physical chemistry has a huge contribution to imaging, diagnostic, refrigeration and various other sectors. From decoding the structure of a crystal to identifying a molecular arrangement via Magnetic Resonance Imaging, physical chemistry will always remain the part and parcel of the manufacturing and health industry. Inorganic on the other hand branches off into the fuming refineries and adventurous mines. Inorganic chemistry has a direct contribution to the economic development of a nation. This is proven by the fact that the development of an economy is gauged by the per capita consumption of a refined metallic component. Organic chemistry on the other hand spans from discovering new proteins and plastics to development of drugs, thereby reducing burden on both healthcare and economy. Last but not the least, research and academic aspects of chemistry are unparalleled and provide great career opportunities.

5. What are the applied aspects of Chemistry?

Chemistry is an integral part of all scientific and economic development procedures. It is that aspect of science that integrates nonliving physical aspects of the physical world to the thriving consumer world. From paints to silicon chips, from plastics to kerosene, it would be safe to say that without the development in terms of chemistry we would still be living in the pre-industrial era. In fact in today’s modern world, the number of natural resources that the economy owns matters less than how efficiently we utilize the same. Chemistry stands at the center stage of the refining and metallurgical industry. Unsurprisingly careers and scopes in chemistry are immense and extremely rewarding both at a personal and public level. Apart from industries, chemistry finds itself in the limelight in the sectors of health and therapeutics. Every new alteration of therapy to the discovery of novel antibiotics which would be effective against the most resistant strains of pathogens, has their deep roots in organic and physical chemistry. Hence study of Chemistry in class 12 level and below opens lots of doors for students to have a bright and secure future.
