Original practice preview

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

Example 1 · difficulty 4/5

A. Ethanoic acid
B. Butanoic acid
C. Methanoic acid
D. Propanoic acid

Example 2 · difficulty 1/5

Which of the following is the strongest Bronsted base in aqueous solution?

A. Triethylamine
B. Diethylamine
C. Ethylamine
D. Aniline

Example 3 · difficulty 2/5

Propanamide on heating with bromine and aqueous KOH gives:

A. Propan-1-amine
B. Propan-2-amine
C. Ethanamine
D. N-Methylmethanamine

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 2025 Chemistry 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 2025 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.
