NCERT Exemplar Class 12 Chemistry Chapter 8 - The d- and f-Block Elements - Free PDF Download

NCERT Exemplar Class 12 Chemistry Chapter 8 contains approximately 60–70 questions across all types — MCQs (single and multiple correct), very short answer, short answer, matching type, and long answer questions. The exact number may vary slightly between editions

Yes, the NCERT Exemplar Class 12 Chemistry Chapter 8 PDF is available for free download on eSaral. The original Exemplar book is an NCERT publication and is freely accessible. eSaral provides a clean, direct-download version so students can access it without navigating multiple pages.

NCERT Exemplar Class 12 Chemistry Chapter 8 covers The d- and f-Block Elements, including electronic configurations of transition metals, their general properties (magnetic behaviour, variable oxidation states, colour), lanthanoids, actinoids, lanthanoid contraction, and important compounds like potassium permanganate and potassium dichromate. The Exemplar extends the NCERT textbook with application-level and HOTS questions.

NCERT textbook exercises test direct recall and basic application of concepts — ideal for building foundational understanding. NCERT Exemplar questions are at a higher difficulty level, testing analysis, multi-step reasoning, and cross-chapter connections. For board exams, the textbook exercises are sufficient for passing; for 90+ scores and competitive exam preparation, the Exemplar is essential.

Lanthanoid contraction refers to the steady decrease in atomic and ionic radii across the lanthanoid series (Ce to Lu), caused by the poor shielding effect of 4f electrons. It explains why the atomic radii of 4d and 5d transition metals of the same group are nearly equal. This concept is a recurring source of assertion-reason and short-answer questions in both board exams and NEET.

Yes. The NTA sets 1–2 questions from d- and f-Block Elements in JEE Main most years. The NCERT Exemplar's MCQ section is particularly useful because it mirrors the application-based single-correct format used in JEE Main. Completing the Exemplar after the NCERT textbook is a standard recommendation from JEE-focused faculty.

Chapter 8 directly contributes around 5 marks to the CBSE Class 12 Chemistry theory paper. It also forms the conceptual foundation for Chapter 9 (Coordination Compounds), which carries higher direct marks. Combined, these two chapters account for roughly 10–12 marks in the board exam, making Chapter 8 one of the most important chapters to prepare thoroughly
