These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 2/5
A transition-metal ion absorbs a particular region of visible light. What colour is observed according to the NCERT explanation?
- A. Exactly the same colour as the absorbed light
- B. The colour complementary to the absorbed light
- C. Only white, because all visible wavelengths are reflected equally
- D. Only black, because absorption of one region removes all visible light
Example 3 · difficulty 1/5
Which ion is expected to be coloured in aqueous solution because it has a partially filled d subshell?
- A. Sc³⁺
- B. Ti⁴⁺
- C. Ni²⁺
- D. Cu⁺

Frequently asked questions
Are these official NEET 2026 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 2026 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.
