$\left[Cr(H_2O)_4Cl_2\right]^{+}$

Vedclass · Answer

(A) The complex ion $\left[Cr(H_2O)_4Cl_2\right]^{+}$ exhibits geometrical isomerism. It is an octahedral complex of the type $\left[Ma_4b_2\right]$,where $M = Cr$,$a = H_2O$,and $b = Cl$. In this type of complex,the two $b$ ligands can be adjacent to each other (cis-isomer) or opposite to each other (trans-isomer). Other options do not show geometrical isomerism: $\left[Pt(NH_3)_3Cl\right]^{+}$ is of the type $\left[Ma_3b\right]$ (square planar),which does not show geometrical isomerism. $\left[Co(NH_3)_6\right]^{3+}$ is of the type $\left[Ma_6\right]$,which is highly symmetrical and does not show isomerism. $\left[Co(CN)_5(NC)\right]^{3-}$ is of the type $\left[Ma_5b\right]$,which does not show geometrical isomerism.
