Vedclass · Answer

(A) The given complex is $[Co(H_2O)(NH_3)_5]I_3$.First,determine the oxidation state of the central metal atom $Co$:Let the oxidation state of $Co$ be $x$.$x + 1(0) + 5(0) + 3(-1) = 0$$x - 3 = 0$$x = +3$According to $IUPAC$ nomenclature rules for coordination compounds:$1$. Name the ligands in alphabetical order: 'ammine' $(NH_3)$ comes before 'aqua' $(H_2O)$.$2$. Since there are $5$ ammine ligands,it is 'pentaammine'.$3$. Since there is $1$ aqua ligand,it is 'aqua'.$4$. The metal is in a cationic complex,so it is named 'cobalt'.$5$. The oxidation state is written in Roman numerals in parentheses: $(III)$.$6$. The counter ion is 'iodide'.Combining these,the name is 'Pentaammineaquacobalt$(III)$ iodide'.

What is the $IUPAC$ name of $[Co(H_2O)(NH_3)_5]I_3$?
