$A$. $Al^{3+}$ $B$. $Cu^{2+}$ $C$. $Ba^{2+}$ $D$. $Co^{2+}$ $E$. $Mg^{2+}$
નીચે આપેલા વિકલ્પોમાંથી સાચો જવાબ પસંદ કરો.
Group | Cations |
Group \(-II\) | \(\mathrm{Cu}^{2+}\) |
Group \(-III\) | \(\mathrm{Al}^{3+}\) |
Group \(-IV\) | \(\mathrm{Co}^{2+}\) |
Group \(-V\) | \(\mathrm{Ba}^{2+}\) |
Group \(-VI\) | \(\mathrm{Mg}^{2+}\) |
The correct order of group number of ions is \(\underset{\text { (B) }}{\mathrm{Cu}^{2+}} < \underset{\text { (A) }}{\mathrm{Al}^{3+}} < \underset{\text { (D) }}{\mathrm{Co}^{2+}} < \underset{\text { (C) }}{\mathrm{Ba}^{2+}} < \underset{\text { (E) }}{\mathrm{Mg}^{2+}}\)
\(\therefore\) The correct order is \(\mathrm{B}, \mathrm{A}, \mathrm{D}, \mathrm{C}, \mathrm{E}\)
