1.

The geometry of the compound `[Pt(NH_(3))_(2)Cl_(2)]` isA. Square planarB. PyramidalC. TetrahedralD. octahedral

Answer» Correct Answer - A
O.S.of Pt (Z = 78) in the complex is `+2(Pt^(2+))Pt^(2+) : [Xe]^(54)4f^(14)5d^(8)`
The eight electrons in 5d-subshell pair up in four d-orbitals followed by `dsp^(2)`-hybridisation. The shape of the complex is square planar.
