Cationic complex is

  • Correct answer
    A
    hexa amino platinum chloride
  • B
    potassium ferro cyanide
  • C
    sodium argento cyanide
  • D
    nickel carbonyl

Solution

A compound in which the complex ion carries positive charge is called cationic complex. For hexaamino platinum chloride, chemical formula is $\left[\mathrm{Pt}\left(\mathrm{NH}_{3}\right)_{6}\right] \mathrm{Cl}_{4}$. $\therefore$ The complex ion $\left[\mathrm{Pt}\left(\mathrm{NH}_{3}\right)_{6}\right]^{4+}$ is positively charge.

Hence, the correct answer is option: 'A'.
