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 1 · difficulty 3/5

18 g of glucose (molar mass 180 g mol⁻¹) is dissolved in 500 g of water. Taking Kb for water as 0.52 K kg mol⁻¹ and its normal boiling point as 373.15 K, the boiling point of the solution will be closest to:

A. 373.15 K
B. 375.75 K
C. 373.36 K
D. 373.25 K

Example 2 · difficulty 3/5

An aqueous solution containing 0.42 g of a protein in 250 cm³ of solution develops an osmotic pressure of 2.46 × 10⁻³ bar at 300 K. Using R = 0.083 L bar K⁻¹ mol⁻¹, the molar mass of the protein is approximately:

A. 1.7 × 10⁴ g mol⁻¹
B. 6.8 × 10⁴ g mol⁻¹
C. 1.7 × 10³ g mol⁻¹
D. 1.7 × 10⁵ g mol⁻¹

Example 3 · difficulty 3/5

Acetic acid associates in benzene to form double molecules (dimers). If the degree of association of acetic acid in a particular benzene solution is 0.8, its van't Hoff factor (i) is:

A. 0.4
B. 0.6
C. 0.8
D. 1.2

Frequently asked questions

Are these official NEET 2017 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 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.
