MCQ
The complex chlorocompound diaquatriammine cobalt $(III)$  chloride is represented as
  • A
    $[Co{(N{H_3})_3}\,{({H_2}O)_3}]C{l_2}$
  • B
    $[Co{(N{H_2})_3}\,\,{({H_2}O)_2}]C{l_2}$
  • C
    $[CoCl{(N{H_3})_3}\,\,{({H_2}O)_2}]C{l_3}$
  • ✓
    $[CoCl{(N{H_3})_3}\,\,{({H_2}O)_2}]C{l_2}$
✓

Answer

Correct option: D.
$[CoCl{(N{H_3})_3}\,\,{({H_2}O)_2}]C{l_2}$
d
Chlorodiaquatriamminecobalt $(III)$ chloride is $\left[ CoCl \left( NH _3\right)_3\left( H _2 O \right)_2\right] Cl _2$. Since.Co has $+3$ charge so 2 chloride ion will be out of the complex ion and 1 within the complex to satisfy primary valency.
