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

Question:

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

  1. $\mathrm{V}^{2+}<\mathrm{Cr}^{2+}<\mathrm{Mn}^{2}<\mathrm{Fe}^{2+}$ : paramagnetic behaviour

  2. $\mathrm{Ni}^{2+}<\mathrm{Co}^{2+}<\mathrm{Fe}^{2+}<\mathrm{Mn}^{2+}$ : ionic size

  3. $\mathrm{Co}^{3+}<\mathrm{Fe}^{3+}<\mathrm{Cr}^{3+}<\mathrm{Sc}^{3+}:$ stability in aqueous solution

  4. $\mathrm{Sc}<\mathrm{Ti}<\mathrm{Cr}<\mathrm{Mn}:$ number of oxidation states


Correct Option: 1

Solution:

 Solution Not Required
