Consider the following: Complex Coordination number (A) CuCl 2 ( i ) 6 ( B ) Ni ( CO ) 4 ( ii ) 5 ( C ) PtCl 6 4 - ( iii ) 4 ( D ) Ni NH 3 6 2 + ( iv ) 2 Proper matching is:

A ( iv ) , B ( iii ) , C ( i ) , D ( i )

A ( i ) , B ( ii ) , C ( iii ) , D ( iv )

A ( iii ) , B ( iv ) , C ( ii ) , D ( iv )

A ( i ) , B ( iii ) , C ( ii ) , D ( iv )

The pair in which both the species have the same magnetic moment (spin only) is:

Cr H 2 O 6 2 + and Fe H 2 O 6 2 +

Co OH 4 2 – and Fe NH 3 6 2 +

Mn H 2 O 6 2 + and Cr H 2 O 6 2 +
