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 limiting molar conductivities of HCl, CH₃COONa and NaCl are 426, 91 and 126 S cm² mol⁻¹, respectively. What is Λₘ° of CH₃COOH?

  • A. 301 S cm² mol⁻¹
  • B. 335 S cm² mol⁻¹
  • C. 426 S cm² mol⁻¹
  • D. 391 S cm² mol⁻¹

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 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.
