        Which of the following complexes show linkage isomerism? (a)                (b) (c)                  (d)  

    Answer:

                        (a, c) Coordination compounds containing a ligand with more than one non-equivalent binding position (known as ambident ligand) show linkage isomerism. e.g.,  contains  which have two donor sites N and 0 can be shown by arrow (®) as  contains SCN which have two different donor sites S and N can be shown by arrow (®) as                               Hence,  and  show linkage isomerism. While  and  has no ambident ligand. So, these two will not show linkage isomerism. Hence, options (a) and (c) are correct choices.
