Which of the following complex has a possibility to exist as meridional isomer?

Options

  1. A[ Co ( NH 3 ) 3 ( NO 2 ) 3 ]
  2. B[ Pt   ( NH 3 ) 2 Cl 2 ]
  3. C[ Co ( en ) 2 Cl 2 ]  
  4. D  [ Co ( en ) 3 ]

Correct answer

A. [ Co ( NH 3 ) 3 ( NO 2 ) 3 ]

Step-by-step solution

The type of the complex MA 3 B 3 exhibit the geometrical isomerism fac-mer isomerism. When three ligands and the metal are in one plane, the isomer is said to be meridional, or mer. [ Co ( NH 3 ) 3 ( NO 2 ) 3 ] can show facial and meridional isomerism.
