Unit V: States of Matter: Gases and Liquids.Check the names of the units dropped from the NCERT textbook along with topics in these 5 units, in the table below. Earlier there used to be 14 units covered in the Class 11 Chemistry syllabus which are now reduced to 9. Get here the complete list of chapter-wise topics deleted from the latest Chemistry NCERT Book of Class 11 CBSE. Thus, it was suggested to students that they note these down and not waste time preparing deleted units or chapters.ĬBSE Class 11 Chemistry List of Rationalised Content 2023-24 These updates are for the academic year 2023–24, and the paper will be formed based on this.
