Question

Which among the following is a neutral complex?

• 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 1

Answer: (C)

$[Pt(NH_{3})_{2}Cl_{2}]$

Answer 2

A neutral complex is a complex ion which have no charge on it. Among the given options $\left[ Pt \left( NH _{3}\right)_{2} Cl _{2}\right]$ is a neutral complex. The type of complexes in other options are as follows:

(a) $\left[ Fe \left( H _{2} O \right)_{6}\right] Cl _{3}$ - cationic complexes

(b) $\left[ Ni \left( NH _{3}\right)_{6}\right] Cl _{6}$ - cationic complexes

(d) $K \left[ Ag \left( CN _{2}\right)\right]$ - anionic complexes
