These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 2/5
What is the main electronic reason that transition elements commonly show variable oxidation states?
- A. Only inner-shell p electrons participate in their bonding
- B. Their d subshells are always completely filled
- C. The ns and (n−1)d electrons have comparable energies and can both participate in bonding
- D. Their ns electrons are too tightly bound to be removed
Example 3 · difficulty 3/5

- A. Sc²⁺ is [Ar] 3d⁰, while Zn²⁺ is [Ar] 3d⁹
- B. Sc³⁺ is [Ar] 3d¹, while Zn²⁺ is [Ar] 3d⁹
- C. Sc⁺ is [Ar] 3d⁰, while Zn³⁺ is [Ar] 3d¹⁰
- D. Sc³⁺ is [Ar] 3d⁰, while Zn²⁺ is [Ar] 3d¹⁰
The evidence-first practice loop
- 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
- 2. Attempt closed-bookExpose the concept or execution gap before rereading.
- 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions
Are these official NEET 2023 Chemistry D- and F-Block Elements PYQs?
No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.
How should I use the NEET 2023 paper?
Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
