The complex(es), which can exhibit the type of isomerism shown by [Pt⁡(NH3)2Br2]\left[\operatorname{Pt}\left(\mathrm{NH}_3\right)_2 \mathrm{Br}_2\right] , is(are) :

[en =H2NCH2CH2NH2=\mathrm{H}_2 \mathrm{NCH}_2 \mathrm{CH}_2 \mathrm{NH}_2 ]

Multiple Choice Options

  • A [Pt(en)(SCN)2]\left[\mathrm{Pt}(\mathrm{en})(\mathrm{SCN})_2\right]
  • B [Zn(NH3)2Cl2]\left[\mathrm{Zn}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}_2\right]
  • C [Pt(NH3)2Cl4]\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}_4\right]
  • D [Cr(en)2(H2O)(SO4)]+\left[\mathrm{Cr}(\mathrm{en})_2\left(\mathrm{H}_2 \mathrm{O}\right)\left(\mathrm{SO}_4\right)\right]^{+}
