Original practice preview

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

Example 1 · difficulty 3/5

Complete acetylation of glucose with acetic anhydride gives glucose pentaacetate. Taken together with the molecular formula C₆H₁₂O₆ and its behaviour as an aldohexose, this observation establishes that glucose contains:

A. five –OH groups, one of which is a primary alcoholic –CH₂OH group, along with one aldehyde group
B. six hydroxyl groups and no carbonyl group
C. five hydroxyl groups and one ketonic group
D. five ether linkages formed on a fully open-chain skeleton

Example 2 · difficulty 2/5

A nucleoside differs from a nucleotide in that the nucleoside lacks:

A. a nitrogenous base
B. the glycosidic linkage joining the base to the sugar
C. a pentose sugar unit
D. a phosphate group

Example 3 · difficulty 3/5

On boiling, the transparent egg white (albumin) turns into an opaque white solid that is insoluble in water. Which statement correctly describes this change?

A. Secondary and tertiary structures are disrupted by disturbance of hydrogen bonds and other weak interactions, while the amino acid sequence (primary structure) remains intact
B. Peptide bonds are hydrolysed, releasing the constituent free amino acids
C. The protein is converted from a fibrous form into a globular form
D. Only the quaternary structure is lost, the alpha-helical segments remaining untouched

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 2017 Chemistry Biomolecules 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 2017 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.
