Options
- APtCl ₂ .2 NH ₃ shows stereoisomers.
- BPtCl ₄ 4 NH ₃ has maximum electrical conductance at infinite dilution.
- CCo ( NO ₂ )₃ 3 KNO ₂ is colourless.
- DCrCl ₃ 6 NH ₃ has the maximum spin only magnetic moment.
Correct answer
D. CrCl ₃ 6 NH ₃ has the maximum spin only magnetic moment.
Step-by-step solution
PtCl ₂ 2 NH ₃ is [ Pt ( NH ₃ )₂ Cl ₂ ] CrCl ₃ .6 NH ₃ is [ Cr ( NH ₃ )₆ ] Cl ₃ PtCl ₄ 4 NH ₃ is [ Pt ( NH ₃ )₄ Cl ₂ ] Cl ₂ Co ( NO ₂ )₃ 3 KNO ₂ is K ₃ [ Co ( NO ₂ )₆ ]
