NEET Mock Tests for d- and f-Block Elements

Master The d and f Block Elements for NEET 2026-2027: Free Chapter-Wise Mock Tests

This crucial chapter carries 3-4 direct questions (12 - 16 marks) in NEET Chemistry, making it essential for your 650+ score. Our free NEET mock tests specifically target transition elements' electronic configurations, oxidation states, and magnetic properties - the most frequently tested concepts. Mastering this chapter gives you an edge in both Chemistry and Biology (metalloenzymes). Neetbharath.in's chapter-wise NEET mock tests help you conquer these concepts through repeated, exam-pattern practice.

Key Syllabus Topics and Updates

Syllabus: General introduction, electronic configurations, occurrence, and characteristics of transition elements; General trends in properties such as physical properties, ionization enthalpy, oxidation states, atomic radii, color, catalytic behavior, magnetic properties, complex formation; Preparation, properties, and uses of compounds like K₂Cr₂O₇ and KMnO₄; Lanthanoids and actinoids, including electronic configurations, oxidation states, and lanthanoid contraction.

As per NTA's latest syllabus, focus on: transition elements (3d series), preparation-properties of K₂Cr₂O₇/KMnO₄, lanthanoid contraction, and catalytic properties. Note: Chemical reactivity of lanthanoids is excluded. Our updated NEET mock tests 2026-2027 reflect all syllabus changes with 15+ practice sets.

Most Important Topics for NEET

Prioritize these high-yield topics, reflected in our 15+ NEET mock tests:

• Electronic configurations - 23% of chapter questions (Cr: 3d⁵4s¹, Cu: 3d¹⁰4s¹)
• KMnO₄/K₂Cr₂O₇ - 19% weightage (oxidizing actions in acidic/alkaline media)
• Magnetic properties - 15% questions (calculate μ for Fe³⁺, Co²⁺ etc.)
• Lanthanoid contraction - 12% marks (Zr/Hf similarity consequences)
• Catalytic properties - 11% (V₂O₅, Fe, Ni in industrial processes)
• Ion colors - 8% (Mn²⁺: pink, Fe³⁺: yellow, Cu²⁺: blue)

Common Mistakes to Avoid

Dodge these pitfalls with our 15+ NEET mock tests' instant feedback:

• Zn/Cd/Hg as transition elements - They're not! (d¹⁰ configuration)
• MnO₄^- vs Cr₂O₇^2- reactions - 62% students mix them up (practice side-by-side in Mock Test 7)
• Lanthanoid vs Actinoid chemistry - Compare through our comparative tables (Mock Test 12)
• Magnetic moment calculation - Remember spin-only formula √[n(n+2)] (5 error traps in Mock Test 3)
• Cu⁺ stability - It disproportionates! (Tested in 3/15 mock tests)
