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. 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
  2. 2. Attempt closed-bookExpose the concept or execution gap before rereading.
  3. 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.
