Can you do a comparative study of previous syllabus of Chemistry chapter 9th and 10th with that of new supplementary syllabus?

<p>Earlier, Class 11 Chemistry included full chapters on Hydrogen and s-block elements, covering topics like isotopes, hydrides, alkali and alkaline earth metals. But in the new supplementary syllabus, both Chapter 9 and 10 have been completely removed to reduce academic load. These deletions are part of NCERT's rationalization under NEP 2020. So now, you won't find hydrogen or s-block topics in your core syllabus, though they still matter for competitive exams like NEET or JEE.</p>
