Which of the following arrangements does not represent the correct order of the property stated against it?
Ni2+ < Co2+ < Fe2+ < Mn2+ : ionic size
Co3+ < Fe3+ < Cr3+ < Sc3+ : stability in aqueous solution
Sc < Ti < Cr < Mn : number of oxidation states
V2+ < Cr2+ < Mn2+ < Fe2+ : paramagnetic behaviour
