Choose the incorrect statement from the following.
Options
- AA tetrahedral complex of the type [ Ma ₂ b ₂] does not show geometrical isomerism
- BIn a coordination entity of the type [ Ma 2( bb )₂]²⁺ only the cis-isomer is optically active
- CCoordination entities of the type [ Ma ₃ b ₃] do not exhibit geometrical isomerism
- DSquare planar complex  of the type [Mabcd] has 3 possible geometrical isomers
Correct answer
C. Coordination entities of the type [ Ma ₃ b ₃] do not exhibit geometrical isomerism
Step-by-step solution
In a tetrahedral complex of the type [Ma₂b₂] , all positions are equivalent relative to each other, meaning there is no distinction between cis and trans positions. Thus, it does not show geometrical isomerism. This statement is correct. For a coordination entity of the type [Ma₂(bb)₂]²⁺ , where (bb) is a symmetrical bidentate ligand, the cis-isomer lacks a plane of symmetry and is optically active, while the trans-isomer possesses a plane of symmetry and is optically inactive. This statement is correct. Coordinati
