You are given the following two complexes X and Y which are isomers of each other, X is Hg [Co(SCN)_(4)]. It is further given that 'spin only' magnetic moment of X is found to be 3.78 BM and that of Y is 1.73 B.M. Then which of the following is correct ?

Answer»

Anion of X will be TETRAHEDRAL and that of Y will be square planar
Anion of X will be square planar but that of Y will be tetrahedral
Both the anions will be tetrahedral
Both the anions will be square planar

Solution :`X rightarrow Hg[CO(SCN)_(4)],Y rightarrow Hg[CO(NCS)_(4)]`
