Which formula and name combination is incorrect?

  • A
    $\begin{aligned} & \mathrm{K}_3\left[\mathrm{Al}\left(\mathrm{C}_2 \mathrm{O}_4\right)_3\right]-\text { Potassium } \\ & \text { trioxalatoaluminate (III) }\end{aligned}$
  • B
    $\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}\left(\mathrm{NO}_2\right)\right]-$ Diamminechloridonitrito -N-platinum (II)
  • Correct answer
    C
    $\left[\mathrm{CoCl}_2(\mathrm{en})_2\right] \mathrm{Cl}-$ Dichloridodiethylenediammine cobalt (II) chloride
  • D
    $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4\left(\mathrm{H}_2 \mathrm{O}\right) \mathrm{Cl}\right] \mathrm{Cl}_2-$ Tetraammineaquachloridocobalt (HI) chloride

Solution

Formula and name combination given in option (c) is incorrect. Its correct form is as follows. $\left[\mathrm{CoCl}_2(\mathrm{en})_2\right] \mathrm{Cl}$ - Dichloridebis(ethylene diamine) - cobalt (III) chloride.

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