Question

When air is bubbled through solution of $Co\left(II\right)$ chloride and ammonium carbonate. Compound ($X$) having composition $Co\left({CO}_3\right).Cl.4{NH}_3$ is formed. Compound ($X$) when treated with conc. $HCl$ gives a violet coloured compound ($Y$) having composition $Co{Cl}_3.4{NH}_3$. Compound ($X$) when treated with a mixture of $HCl$ and $H_2{SO}_4$ gives a green coloured compound ($Z$) having composition $Co{Cl}_3.4{NH}_3$.

• A. Optical
• B. Geometrical
• C. both (a) and (b)
• D. Ionization isomerism

Answer 1

The correct option is B Geometrical
