Question

For the square planar complex [Mabcd] where M is the central atom and a,b,c,d are monodentate ligands, the number of possible geometrical isomers are:

• A. one
• B. two
• C. three
• D. four

Answer 1

Answer: (C)

three

For the square planar complex [Mabcd] where M is the central atom and a,b,c,d are monodentate ligands, the number of possible geometrical isomers are three. In isomer I, C is opposite to A. In isomer II, D is opposite to A. In isomer III, B is opposite to A.
