Question

Pick the correct name of .[ CoONH 3)3 Cl ] C 2 (A) chloropentammine cobalt (II) chloride (B) pentammine chloro cobalt (III) chloride (C) chloropentammine cobalt (III) (D) pentammine cobalt (III) chloride

Tardigrade Admin · Accepted Answer

[ Co ( NH 3)5 Cl ] Cl 2 In this case the ligands are chloro and amine. The complex is cation and chloride is anion. The oxidation state of cobalt is III as x+5(0)-1-2 =0 x =+3 Its name is pentammine chloro cobalt(III) chloride.

Q. Pick the correct name of $[C o ON H_{3})_{3} Cl] C_{2}$

chloropentammine cobalt (II) chloride

pentammine chloro cobalt (III) chloride

chloropentammine cobalt (III)

pentammine cobalt (III) chloride

$[C o (N H_{3})_{5} Cl] C l_{2}$
In this case the ligands are chloro and amine. The complex is cation and chloride is anion. The oxidation state of cobalt is III as
$x + 5 (0) - 1 - 2 = 0$
$x = + 3$
Its name is pentammine chloro cobalt(III) chloride.
