JEE Main 4 April 2024, Shift 2, Chemistry Q65

Question 65 of 90 in this shift, Chemistry question 5 of 30, Section A.

For a strong electrolyte, a plot of molar conductivity against (concentration)1/2^{1/2} is a straight line, with a negative slope, the correct unit for the slope is
  1. (1)S cm2 mol−1 L1/2\mathrm{S\,cm^2\,mol^{-1}\,L^{1/2}}
  2. (2)S cm2 mol−3/2 L\mathrm{S\,cm^2\,mol^{-3/2}\,L}
  3. (3)S cm2 mol−3/2 L−1/2\mathrm{S\,cm^2\,mol^{-3/2}\,L^{-1/2}}
