The correct statement on the isomerism associated with the following complex ions, \[{{[Ni{{({{H}_{2}}O)}_{5}}N{{H}_{3}}]}^{2+}},\] \[{{[Ni{{({{H}_{2}}O)}_{4}}{{(N{{H}_{3}})}_{2}}]}^{2+}}\]and \[{{[Ni{{({{H}_{2}}O)}_{3}}{{(N{{H}_{3}})}_{3}}]}^{2+}}\]is: JEE Main Online Paper (Held On 10 April 2015)

A)   and  show geometrical andoptical isomerism

B)   and  show geometrical and optical isomerism

C)  and  show only geometrical isomerism

D)   and  show only geometrical isomerism

Correct Answer: A

Solution :

                 C is \[={{\left[ Ni{{\left( {{H}_{2}}O \right)}_{4}}{{\left( N{{H}_{3}} \right)}_{2}} \right]}^{+2}}\And \]facial \[{{\left[ Ni{{\left( {{H}_{2}}O \right)}_{3}}{{\left( N{{H}_{3}} \right)}_{2}} \right]}^{+2}}\]have optical isomers.
