The possible number of structural and stereo isomers for the complex M B r 2 C l 2 S O 4 is

Correct answer

5

Step-by-step solution

The compound also shows ionization isomerism. The ionization isomers are (i) M B r 2 S O 4 C l 2 (ii) M C l 2 S O 4 B r 2 (iii) M B r C l S O 4 B r C l The complex ion [ M B r 2 C l 2 ] 2 + shows geometrical isomerism. The geometrical isomers are (i) cis- M B r 2 C l 2 S O 4 (ii) trans- M B r 2 C l 2 S O 4 Thus, a total of five (3 structural and 2 geometrical) isomers are formed.
