Hello!

D and F block elements is the eighth chapter in the 12th standard Chemistry Syllabus. It is included in the section, Inorganic Chemistry - II, which carries a weightage of 12% in the NEET exam. Of the 12%, D and F block elements comprises 4% of the section or an average of 2 questions.

The following are some of the patterns of questions that are usually asked in NEET exam:

1) Questions based on general properties and classification of D and F block elements

2) Two compounds are given and questions based on their relative stability are asked

3) Questions based on properties of acids and bases within D and F block elements

4) Questions based on oxidation states, electronegativity, ionization enthalpy, covalent state and reactivity

5) Reactions with colour change or precipitate formation

6) Questions based on oxidation and reduction reactions

7) Elements/compounds are marked with letters A, B, C, D, etc. and a reaction involving them is described; the student should identify A, B, C, D, etc.

8) Questions based on Lanthanoid contraction

9) Questions based on physical and chemical characteristics of the compounds

10) Questions where the student should identify the catalyst in a reaction

11) A set of statements are given and the wrong/right statement must be identified

12) Questions based on solutions and alloy formations

All the best!
