Current Question (ID: 18684)

Question:

$\text{The correct IUPAC name for } \text{Mn}_3(\text{CO})_{12} \text{ is:}$

Options:

1. $\text{Dodecacarbonylmanganate(0)}$
2. $\text{Dodecacarbonylmanganate(II)}$
3. $\text{Dodecacarbonyltrimanganese(0)}$
4. $\text{Manganicdodecacarbonyl0}$

Solution:

$\text{STEP 1: The given complex is } \text{Mn}_3(\text{CO})_{12}$ $\text{Follow IUPAC rules:}$ $1.) \text{The central metal atom is Manganese (Mn) which is in zero oxidation state as CO is a neutral ligand. The oxidation state is written in parenthesis.}$ $2.) \text{Three Mn atoms are present. Hence, the prefix "tri" is used.}$ $3.) \text{For 12 carbonyl groups, the prefix "dodeca" is used.}$ $\text{STEP 2: Thus, the correct IUPAC name of } \text{Mn}_3(\text{CO})_{12} \text{ is dodecacarbonyltrimanganese(0).}$
