The number of geometrical isomers in the following metal complexes Ni ( CO )₄, [ Ru ( H ₂ O )₃ Cl ₃ ], [ CuCl ₂ ( NH ₃ )₄ ]⁺ and [ PtCl ₂ ( NH ₃ )₂ ] are
Options
- A1,0,2,2
- B0,2,2,2
- C2,0,0,2
- D2,0,2,2
Correct answer
B. 0,2,2,2
Step-by-step solution
The complex Ni ( CO )₄ is a tetrahedral complex of the type MA₄ . Tetrahedral complexes of the type MA₄ or MA₃B do not exhibit geometrical isomerism. Thus, the number of geometrical isomers is 0 . The complex [ Ru ( H ₂ O )₃ Cl ₃] is an octahedral complex of the type MA₃B₃ . This type of complex exhibits two geometrical isomers: the facial (fac) isomer and the meridional (mer) isomer. Thus, the number of geometrical isomers is 2 . The complex [ CuCl ₂( NH ₃)₄]⁺ is an octahedral complex of the type MA₄B₂ . This type
