Which among the following is a neutral complex?

Options

A. `[Fe(H_(2)O_(6)]Cl_(3)`
B. `[Ni(NH_(3))_(6)]Cl_(2)`
C. `[Pt(NH_(3))_(2)Cl_(2)]`
D. `k[Ag (CN)_(2)]`

Answer

C

Explanation

A neutral complex is a complex ion which have no charge on it. Among the given options
`[Pt(NH_(3))_(2)Ci_(2)]` is neutral complex. The type of complexes in other options are as follows:
(a) `[Fe(H_(2)O)_(6)]CI_(3)` - cationic complexes
(b) `[Ni(NH_(3))_(6)]CI_(6)` - cationic complexes
(d) `k[Ag (CN_(2))]`- anionic complexes
