Q. The correct statement on the isomerism associated with the following complex ions.
(a) $\left(\left[N i \left(H_{2} O\right)_{5} N H_{3}\right]\right)^{2 +}$
(b) $\left(\left[N i \left(H_{2} O\right)_{4} \left(N H_{3}\right)_{2}\right]\right)^{2 +} \, $ and
(c) $\left(\left[N i \left(H_{2} O\right)_{3} \left(N H_{3}\right)_{3}\right]\right)^{2 +}$ is:

Solution:

$\left(\left[N i \left(H_{2} O\right)_{5} N H_{3}\right]\right)^{2 +}$ does not show any isomerism

$\left(\left[N i \left(H_{2} O\right)_{4} \left(N H_{3}\right)_{2}\right]\right)^{2 +} \, $ shows cis-trans (geometrical) isomerism
$\left(\left[N i \left(H_{2} O\right)_{3} \left(N H_{3}\right)_{3}\right]\right)^{2 +}$ shows fac-mer isomerism
