Question

In a complex MA₃X₃, unidentate ligands A and X may give:

• A. two geometrical isomers one of which can be resolved into a pair of enentiomers
• B. two geometrical isomers which can be resolved into a pair of enentiomers
• C. two geometrical isomers
• D. three geometrical isomers

Answer 1

The correct option is C

two geometrical isomers

MA₃X₃ can exist as two geometrical isomers one facial isomer; and the other isomer will be meridianal isomer.
