A) hexamine cobalt trichloride
B) hexamine cobalt (III) chloride
C) hexamoniacobalt trichloride
D) cobalt hexamine chloride
Correct Answer: B
Solution :
\[[Co{{(N{{H}_{3}})}_{6}}]C{{l}_{3}}\] This is a cationic complex, so the name of the metal is written without any characteristic ending. Ligand is \[N{{H}_{3}}\], ie, amine. It is a neutral ligand. Oxidation state of cobalt is III as \[x+6\,(0)-3=0\] \[x=3\] Therefore, the name of compound is Hexaammine cobalt(III) chloride. Note- When the complex is anionic, the name of the central metal atom ends in -ate.You need to login to perform this action.
