MCQ
The correct $\text{IUPAC}$ name of $\mathrm{Mn}_3(\mathrm{CO})_{12}$ is:
- AMangesedodecylcarbonyl$(0)$
- BDodecacarbonylmanganate$(0)$
- CDodecacarbonylmanganic$(II)$
- ✓Dodecacarbonyltrimanganese$(0)$
✓
Answer
Correct option: D.
Dodecacarbonyltrimanganese$(0)$
The correct $\text{IUPAC}$ name of $\mathrm{Mn}_3(\mathrm{CO})_{12}$ is dodecacarbonyltrimanganese$(0).$ The central metal atom is a cobalt atom in zero oxidation state. The oxidation state is written in parenthesis.
Three such $Mn$ atoms are present. Hence, the prefix tri is used$. 12$ carbonyl groups are present. Hence, the prefix dodeca is used.
