Question

The one that is not expected to show isomerism is ______.

पर्याय

• \[\ce{[Ni(NH3)4 (H2O)2]^{2+}}\]

• \[\ce{[Ni(en)3]^{2+}}\]

• \[\ce{[Ni(NH3)2Cl2]}\]

• \[\ce{[Pt(NH3)2Cl2]}\]

Answer 1

The one that is not expected to show isomerism is \[\underline{\ce{[Ni(NH3)2Cl2]}}\].

Explanation:

\[\ce{[Ni^{2+} (NH3)2 Cl2] => Ni^{2+} => 3d^8 4s^0}\]

⇒ sp³ hybridisation ⇒ tetrahedral

So, \[\ce{[Ni(NH3)2Cl2]}\] does not show isomerism.
