Original practice preview

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

Example 1 · difficulty 1/5

Which description correctly compares the molar conductivity of strong and weak electrolytes as their solutions are diluted?

A. It decreases slowly for strong electrolytes but increases sharply for weak electrolytes.
B. It increases slowly for strong electrolytes but increases sharply for weak electrolytes.
C. It remains constant for strong electrolytes but decreases for weak electrolytes.
D. It increases sharply for strong electrolytes but remains constant for weak electrolytes.

Example 2 · difficulty 1/5

According to Kohlrausch’s law, which expression gives the limiting molar conductivity of MgCl₂?

A. Λₘ°(MgCl₂) = 2λ°(Mg²⁺) + λ°(Cl⁻)
B. Λₘ°(MgCl₂) = λ°(Mg²⁺) + λ°(Cl⁻)
C. Λₘ°(MgCl₂) = λ°(Mg²⁺) + 2λ°(Cl⁻)
D. Λₘ°(MgCl₂) = 2λ°(Mg²⁺) + 2λ°(Cl⁻)

Example 3 · difficulty 3/5

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 2023 Chemistry Electrochemistry 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 2023 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.
