As per the CBSE Term-2 date sheet, the Class 12 Chemistry board exam will be held on Saturday, May 7, 2022, from 10.30 am to 12.30 pm. There is not much time for students to pack up their preparations and work on the revision. They need to focus more on NCERT textbooks and keep supplementary books on the side.
The knowledge of the syllabus is a must-to-know point before starting preparation and revision for any examination. Moreover, Chemistry is an easy to handle but tricky subject. Students need to strengthen their fundamental concepts for an excellent outcome in Chemistry. And for this purpose, without any doubt, they can consider NCERT textbooks, NCERT examples, and NCERT solutions. In other words, NCERT books are the best for Chemistry board exam preparations.

Term 2 Chemistry Syllabus
Chemistry is important as well as an interesting subject. If a student can grasp all Chemistry Concepts included in their course, then, without any question, he can achieve an outstanding score with half the hard work. For selecting a career in engineering or medical field, then Chemistry is a must to take the subject.
Term-II comprises seven units, and these combined units consist of 35 marks. There will be 12 questions with internal choice, divided into three sections. Questions will be asked from different formats, i.e., case-based, situation-based, short answer type, and long answer type.
Electrochemistry, Chemical Kinetics, Surface Chemistry, d -and f -Block Elements, Coordination Compounds, Aldehydes, Ketones, and Carboxylic Acids, and Amines are the units under the CBSE Class 12 Term 2 Chemistry syllabus.

Term 2 Practicals Syllabus
At the end of Term II, a 15-mark Chemistry Practical would be conducted under the supervision of Board appointed external examiners. It would contribute to the overall practical marks for the subject.
In case the situation of lockdown continues beyond December 2021, a Practical Based Assessment (pen-paper) of 10 marks and Viva 5 marks would be conducted at the end of Term 2, jointly by the external and internal examiners. And marks would be submitted by the schools to the Board. It would contribute to the overall practical marks for the subject.
