JEE Main 2024 Chemistry question
The 'spin only' magnetic moment value of MO₄²⁻ is BM. (Where M is a metal having least metallic radii among Sc, Ti, V, Cr, Mn and Zn). (Given atomic number: Sc = 21, Ti = 22, V = 23, Cr = 24, Mn = 25 and Zn = 30)
Answer: 0
Solution
As per the printed key, M is taken as Cr (least metallic radius in the source's data table): CrO₄²⁻
