Options
- AB, C, A, D, E
- BE, C, D, B, A
- CE, A, B, C, D
- DB, A, D, C, E
Correct answer
D. B, A, D, C, E
Step-by-step solution
\begin{array}{|c|c|}\hlineGroup & Cations \hline Group-II & \mathrm{Cu}^{2+}\hline Group-III & \mathrm{Al}^{3+}\hline Group-IV & \mathrm{Co}^{2+}\hline Group-V & \mathrm{Ba}^{2+}\hline Group-VI & \mathrm{Mg}^{2+}\hline\end{array} The correct order of group number of ions is\underset{(\mathrm{B})}{\mathrm{Cu}^{2+}}\lt \underset{(\mathrm{A})}{\mathrm{Al}^{3+}}\lt \underset{(\mathrm{D})}{\mathrm{Co}^{2+}}\lt \underset{(\mathrm{C})}{\mathrm{Ba}^{2+}}\lt \underset{(\mathrm{E})}{\mathrm{Mg}^{2+}} The correct order is $B, A, D, C, E
