NEET 2026 Chemistry, question 62

Question 62 of the NEET 2026 paper (re-exam) is a Chemistry question from Electrochemistry. Its idea, Variation of Molar Conductivity with Concentration, was asked only this once in NEET 2017–2026. The NTA final answer key gives option 1.

Q62 · Chemistry

For a salt XY, which is a strong electrolyte, the plot of Λm\Lambda_m versus c\sqrt{c} has a slope of −90.0-90.0 S cm2^2 mol−3/2^{-3/2} L1/2^{1/2} at 298 K. At 0.01 M concentration of XY, the value of Λm\Lambda_m is 145.0 S cm2^2 mol−1^{-1}. The limiting molar conductivity of Y−\mathrm{Y^-} ion (λY−0\lambda^0_{Y^-}, in S cm2^2 mol−1^{-1}) at 298 K will be

(Given : λX+0\lambda^0_{X^+} = 74.0 S cm2^2 mol−1^{-1})
