Question

Which of the following arrangements does not represent the correct order of the property stated against it?

विकल्प

• V²⁺ < Cr²⁺ < Mn²⁺ < Fe²⁺: paramagnetic behaviour

• Ni²⁺ < Co²⁺ < Fe²⁺ < Mn²⁺: ionic size

• Co³⁺ < Fe³⁺ < Cr³⁺ < Sc³⁺: stability in aqueous solution

• Sc < Ti < Cr < Mn: number of oxidation states

Answer 1

V²⁺ < Cr²⁺ < Mn²⁺ < Fe²⁺: paramagnetic behaviour
