NEET 2020 Chemistry Solutions Questions
Use this page to connect the official 2020 paper with current Chemistry practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.
What to master
concentration terms, vapour pressure, colligative properties and abnormal molar mass.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 1/5
A homogeneous alloy of copper dissolved in gold is an example of which type of solution?
- A. Liquid in solid
- B. Solid in solid
- C. Solid in liquid
- D. Gas in solid
Example 3 · difficulty 2/5
In a solution made by dissolving 10 g glucose in 90 g water, which statement is most appropriate?
- A. Both components must be called solvents
- B. Glucose is the solvent because its molar mass is larger
- C. Water is the solvent because it is present in larger amount and determines the liquid state
- D. Glucose is the solvent because it is the nonvolatile component
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 2020 Chemistry Solutions 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.
