Which of the following statement is correct ?

Question

TestHub · Accepted Answer

Option B is correct because the complex can exhibit both ionization and linkage isomerism. Ionization isomerism arises from the exchange of ions inside and outside the coordination sphere, while linkage isomerism occurs when a ligand can bind to the metal center through different atoms (e.g., $N O_{2}$ can bind through N or O).

Option A is incorrect because $C o C l_{3} \cdot 6 N H_{3}$ and $PtC l_{4} \cdot 6 N H_{3}$ do NOT have similar electrical conductivity in aqueous solution.

Option C is incorrect; the correct IUPAC name for $[N i (d m g)_{2}]$ is bis(dimethylglyoximato)nickel(II).

Option D is incorrect because $K_{2} S O_{4} \cdot A l_{2} (S O_{4})_{3} \cdot 24 H_{2} O$ (alum) gives tests for $K^{+}$ , $A l^{3 +}$ , and $S O_{4}^{2 -}$ ions in solution.
