NCERT Class 12 Chemistry Chapter 4 The d-and f-Block Elements Test Mock Test
This free online test covers Chapter 4, The d-and f-Block Elements, from the NCERT Class 12 Chemistry-I textbook. The 30 questions are written directly from the chapter — definitions, processes, worked examples and the points the book italicises — so a score here tells you how much of the chapter actually stuck, not how well you guess. Each answer carries an explanation that says why the right option is right and why the other three fail, which is where most of the learning happens. Attempt it after your first read of the chapter, then again before the exam. There is no negative marking, and you can review the full solution the moment you submit.

Q1.According to the IUPAC definition quoted in the chapter, a transition metal is one that has:
- AAn incomplete d subshell in the neutral atom only, whatever its ions may be like
- BAn incomplete d subshell either in the neutral atom or in one of its ions
- CChemical properties intermediate between those of the s-block and p-block elements
- DPartly filled 4f or 5f orbitals in its ground state
Q2.Zinc, cadmium and mercury of group 12 are not regarded as transition metals because:
- ATheir d orbitals are completely empty in the ground state
- BThey lie outside groups 3 to 12 of the periodic table
- CThey have a full d10 configuration both in the ground state and in their common oxidation states
- DThey are liquids or low melting solids rather than typical metals
Q3.The general outer electronic configuration of the d-block elements is (n-1)d^1-10 ns^1-2, and the element singled out in the chapter as an exception to it is:
- ACopper, whose configuration is 3d10 4s1
- BPalladium, whose configuration is 4d10 5s0
- CSilver, whose configuration is 4d10 5s1
- DChromium, whose configuration is 3d5 4s1
