The d- and f-Block Elements: Class 12 Chemistry (MP Board) important questions and practice
The d- and f-Block Elements is chapter 4 of 10 in MP Board Class 12 Chemistry. Below are the topics the paper draws from, the question types that come up again and again, and a free practice test on this chapter alone.
Topics in this chapter
- Electronic configuration and general properties of transition elements: atomic radii, ionisation enthalpy, oxidation states, colour, magnetic properties, catalytic properties, interstitial compounds, alloys
- Trends in the first row (3d series) and the anomalies of Cr and Cu
- Preparation and properties of potassium dichromate (K2Cr2O7) and potassium permanganate (KMnO4)
- Lanthanoids: electronic configuration, oxidation states, lanthanoid contraction and its consequences
- Actinoids and comparison with lanthanoids
- Applications of d- and f-block elements
What examiners usually ask
- Why do transition elements show variable oxidation states and form coloured compounds?
- Describe the preparation of potassium dichromate from chromite ore and write the effect of changing pH on the chromate-dichromate equilibrium
- What is lanthanoid contraction? Give its two consequences
Exam tip
Reasoning questions dominate: prepare one-line causes for variable oxidation states (ns and (n-1)d electrons), colour (d-d transitions), paramagnetism (unpaired electrons), Zn/Cd/Hg not being typical transition metals, and Mn2+ being more stable than Fe2+; the K2Cr2O7 and KMnO4 preparation equations are also regular.
