Q.
For the square planar complex [M(a)(b)(c)(d)] (where, M= central metal and a,b,c and d are monodentate ligands), the number of possible geometrical isomers are
For [M[a][b][c][d]] square planar complex, the number of possible geometrical isomers is three which is obtained by fixing the position of one of the ligands say a while the other ligands b,c and d are placed trans to it.
