Which of the following is true regarding the following coordination compounds - CrCl ₃ 6 NH ₃, PtCl ₄ 4 NH ₃, Co ( NO ₂ )₃ 3 KNO ₂, PtCl ₂ 2 NH ₃

Options

  1. APtCl ₂ .2 NH ₃ shows stereoisomers.
  2. BPtCl ₄ 4 NH ₃ has maximum electrical conductance at infinite dilution.
  3. CCo ( NO ₂ )₃ 3 KNO ₂ is colourless.
  4. DCrCl ₃ 6 NH ₃ has the maximum spin only magnetic moment.
