Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 1/5

How is ethane-1,2-diamine, commonly represented as en, classified as a ligand?

A. Bidentate, because it coordinates through two nitrogen donor atoms
B. Monodentate, because it forms only one bond in total
C. Ambidentate, because it can coordinate through either nitrogen or carbon
D. Hexadentate, because it contains six hydrogen atoms

Example 2 · difficulty 2/5

Which of the following is an ambidentate ligand?

A. H2O
B. NO2−
C. NH3
D. Ethane-1,2-diamine

Example 3 · difficulty 1/5

What is the denticity of the ligand EDTA4− when it binds through all its donor atoms?

A. 2
B. 4
C. 6
D. 8

Frequently asked questions

Are these official NEET 2020 Chemistry Coordination Compounds 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 2020 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.
