Q4 / 125 · BITSAT 2016 · Chemistry
Which of the following arrangements does not represent the correct order of the property stated against it?
- Correct answerA$\mathrm{V}^{2+}<\mathrm{Cr}^{2+}<\mathrm{Mn}^{2+}<\mathrm{Fe}^{2+}$ :paramagnetic behaviour
- B$\mathrm{Ni}^{2+}<\mathrm{Co}^{2+}<\mathrm{Fe}^{2+}<\mathrm{Mn}^{2+}:$ ionic size
- C$\mathrm{Co}^{3+}<\mathrm{Fe}^{3+}<\mathrm{Cr}^{3+}<\mathrm{Sc}^{3+}:$ stability in aqueous solution
- D$\mathrm{Sc}<\mathrm{Ti}<\mathrm{Cr}<\mathrm{Mn}:$ number of oxidation states
Hence, the correct answer is option: 'A'.
