The correct statement on the isomerism associated with the following complex ions,

[A] \[{{[Ni{{({{H}_{2}}O)}_{5}}N{{H}_{3}}]}^{2+}},\]

[B] \[{{[Ni{{({{H}_{2}}O)}_{4}}{{(N{{H}_{3}})}_{2}}]}^{2+}}\]and

[C] \[{{[Ni{{({{H}_{2}}O)}_{3}}{{(N{{H}_{3}})}_{3}}]}^{2+}}\]is:

A) [A] and [B] show only geometrical isomerism

B) [A] and [B] show geometrical and optical isomerism

C) [B] and [C] show geometrical and optical 7 isomerism

D)  [B] and [C] show only geometrical isomerism

Correct Answer: C

Solution :

[c] \[C\,\text{is}-{{[Ni{{({{H}_{2}}O)}_{4}}{{(N{{H}_{3}})}_{2}}]}^{2+}}\] and facial \[{{[Ni{{({{H}_{2}}O)}_{3}}{{(N{{H}_{3}})}_{3}}]}^{+2}}\] have optical isomers.
